Best Windows Linux Web Browser Programs for Very Old Computers

Lightweight Web Browsers for Windows and Linux

If you use a very old or slow computer, the best light web browser for web browsing would be Maxthon 3, Avant browser, slim browser, K-Meleon, Midori, and Qtweb browsers which use less RAM, and CPU resources. Using these web browsers will make browsing the web faster because these web browsers use designed to run fast by using less RAM, and CPU Cycles while the user is using them.

A web browser which runs fast on slower computer could let you use your old PC for web services like Google Docs, YouTube, Facebook, Gmail, Online Calender, online flash games, etc to do what you typically do with regular programs on the web with web programs which are also called web apps. Web Apps sometimes uses a lot less system resources then Full PC software because most web apps run off of the website not your computer.

Lightweight web browsers like Qtweb will sometimes run faster on older computer which is not always true for the latest versions of Internet Explorer, Google Chrome, Opera, etc which may no be compatible with older operating systems like Windows 2000, 95-98, ME, NT, etc. Even if some web browsers like Internet Explorer are supported, newer web browsers may run very slowly on a slow computer with a Pentium 3 CPU with 192MB of RAM or less, and very little free hard drive space like under 100MB free.

Lightweight web browsers would also be better to use then Internet Explorer 6.0 which is no longer supported, insecure, and very slow compared to light web browsers which I listed in this article.

Lightweight Web Browsers for Desktop PCs


K-Meleon is a Web browser which uses the Gecko Firefox web browser. However the user interface is not as modern as Firefox, and has no add-on supports for installing add-ons from Firefox.com.  The user interface looks like Internet Explorer 5.0. The main advantage is it starts up fast and uses very little system resources, so it is also very speedy on older computer. But, it has not been updated in many years, so it is not the best web browser for newer computers which can use more feature rich web browsers without slowing down. It is also one of the few web browsers which is kind of new which still work with Windows 95-ME.

System Requirements

Windows 95-Windows 7
15 MB hard drive space.



Vivaldi is a new web browser made by former Opera staff members. Its user interface is based on JavaScript, Node.JS, and React. The web browser uses the Blink Web Browser engine like Google Chrome, Opera, and other web browser. Vivaldi is also very custumizable, and has a nice looking user interface with colored tabs, and a flat design. When I use Vivaldi on my Windows, and Linux computer, it runs very quickly. There are also very few un-needed features on Vivaldi, so it won’t become slowed down by features I rarely use. Vivaldi works with both Windows and Linux.



SlimJet is similar to Slim Browser, but it uses the Blink/WebKit Web rendering engine found in Chrome, Chromium, Opera, and other popular web browsers. Slimjet has tabs, bookmarks, clear history, and other features found in Slim Browser. Slimboat and Slim Browser are made by the same company. Slimjet user interface is like Google Chrome and Internet Explorer, so it is easy to learn how to use. Slimjet also uses the Google Chrome web store to install extensions, themes and web apps for it. Slimjet also has a RAM optimization tool in the settings which optimizes your RAM every few minutes to improve your computer’s RAM, and CPU performance. There is a Windows and Linux version of Slimjet. I personally use SlimJet on my Windows 10 based desktops, and laptops, and Slimjet works well on my computers with less than 3GB of RAM, and a slower dual-core CPU.



Maxthon 3 is based on Webkit which Chrome,  and Safari uses and Trident which Internet Explorer browser uses. It has a lot of  features like Password manager, bookmarks, add-ons, themes, and other features you find on web browsers. The user interface also looks very modern and easy to use. The System requirements are also very low for such a new web browser. There is now a Linux version of Maxthon web browser.

Minimum Requirements for Maxthon
500MHz CPU
20MB Disk Space
Windows 2000 / XP / Vista
Internet Explorer 6.0


Maxthon Nitro

Maxthon Nitro is a very fast web browser which has most of the important features like tabs, addresss bar, HTML5 compatibility, a nice user interface, bookmarks, etc. But, it has no-unneeded features which can slow down your web browsing. It is only available for  Windows.


Avant Browser

Avant Browser is also a pretty good feature rich web browser which uses the IE Trident web browser found in Internet Explorer. I used Avant as my main browser for many years before I switch to Google Chrome, and it works great. It has all the features like Bookmarks, password managers, add-ons, custom themes and other features I need. It does not use a lot of RAM, or CPU space. If you prefer using a web browser which is based on Internet Explorer, Avant Browser is the browser for you. It is certainly one of the fastest web browsers which uses the Internet Explorer Trident engine. It works on Windows 2000, XP, Vixta, and 7. You just need a 300 MHz CPU and 128 MB of RAM, and Internet Explorer 6 or higher to be installed.

There is also a version of Avant which uses the Trident, Gecko and Webkit web layout engine on its web browser for improve compatibility, and faster performance by using Webkit, or Gecko which can sometimes be faster than the Trident web layout engins.


Slim Browser

Slim Browser is also a web browser which is similar to Avant except the user interface is more basic, but Slim Browser has all the features a typical user would need like bookmarks, history, form filler, etc. It also use the IE Trident Web browser engine. Slim Browser system requirements are very low. All you need is Windows 98, and Internet Explorer 5.0 installed. It also works on Windows ME, 2000, XP, Vista, and 7.


SlimBoat is a full featured tab web browser which has most of the features which users use on a daily basis. It has tabs, bookmarks, support for plug-ins like Adobe flash, form filler, fast internet download manager, language translator, search, and a simple user interface. It is made by the same developer as Slim Browser, and Slimjet web browser. Slimboat uses the QtWebkit engine on its browser. Slimboat works on both Windows and Linux.

Slimboat is now discontinued, so you should use Slimjet which is made by the same company


Light Firefox

Light Firefox is a light Web browser based on Firefox. It has most of the same features of Firefox, and you can use Firefox add-ons like NoScript and Flash Block which can make Firefox faster by blocking scripts and flash from running. Light’s user interface design is the same as newer versions of Firefox. But, the components and features on Light Firefox are slimmed down, so it performs faster, and use less RAM on a computer by removing unnecessary features which few users use. Light Firefox has a Windows and Linux version.



Palemoon is a web browser based on Firefox, but Palemoon is designed to be fast, and easy to use. It uses its own optimized Goanna Layout engine, and it is designed to run fast on modern CPUs. It also uses the classic Firefox 3 user interface, so it is easier to use for people who are used to the old user interface of Firefox. It has most of the features of Firefox web browser. Palemoon has a Windows and Linux version.



CyberFox is a web browser which is based on Mozilla Firefox’s source code. Most Firefox extensions and themes should work in CyberFox. Cyberfox is optimize for Intel and AMD based x86, and 64bit CPUs, so CyberFox can run faster on your computer because it is optimize for your model of CPU. When I use CyberFox on my computer with 3GB of RAM running Windows 10 and an Intel Core2Dou CPU clocked at 1.86 GHz, Cyberfox seems to run smoother and faster than Firefox. CyberFox can be setup to look like the classic version of Firefox instead of the new version which has the rounded tabs. It is also easy to disable features like Pocket, and Reader Mode in Cyberfox to make it more slim. Cyberfox also does not come with features like Health Report and other data collection services, so it is more private and may run faster by not including these data collection features. If your computer can run Windows 7 and above, it should be fast enough to run CyberFox because CyberFox is supported for Windows 7 to 10.



QtWeb is a webkit based tabbed browser which runs pretty quickly even on older computers. It has tabs, plug-in support, and most of the standard features most other web browsers have. Qtweb has a Windows and Linux version.



QupZilla is a light tab web browser which uses the QtWeb Engine browser. It has bookmarks, history, and more. It uses the native widgets style, and icons from the active theme on major Linux Desktop Environments. It  combines bookmarks, history and rss reader in one well-arranged window to save time, and screen space. QupZilla can import bookmarks from other web browsers. There are also speed dial bookmarks in QupZilla for quickly access your bookmarks on the homepage/quick dial page.



Arora Web Browser is also worth checking out. It uses the WebKit Web Browser like Google Chrome and Safari. It kind of reminds me of a more simple version of Google Chrome. It supports bookmarks, but I but there is no Add-on support like Google Chrome for cool widgets and plug-ins . I can’t find the system requirements, but if your computer has Windows 2000 or higher then you can probably run it. Arora is also available on Linux operating systems like Ubuntu. Arora also supports Adobe Flash Player in Linux. Arora is now discontinued, so I don’t recommend you use it since it may be less safe to use compared to a web browser like Firefox and Chrome which are constantly updated.



Midori Web Browser is also worth looking at, but it is very basic, and does not have much add-on support. It supports Bookmarks, passwords, and all the basic stuff you find in web browser. It uses the WebKit web browser which is also used in Google Chrome and Safari. It also has HTML5 support for playing newer web browser based games, and HTML5 videos on YouTube.

Midori is probably the best light weitght web browser for very old computer since it seems it is still being updated on a regular basis by the developer unlike K-meleon and Arora which had no new versions in years. Midori also seems like the most stable and modern web browser designed for very old computers compared to Epiphany Web Browser for Gnome Linux which crashes often in my experience, and does not support Adobe Flash Player in Ubuntu Linux like Midori. Midori has a Windows and Linux version.



Lunascape is a powerful, lightweight web browser with three Web layout engines which are Trident, Gecko, and WebKit. In Lunascape, you can switch web layout engines quickly in the settions. for better compatibility for websites, and better performance. The web browser is faster at both startup speed and JavaScript execution compared to similar tab Web Browsers which uses Gecko or Webkit web layout engine. Lunascape also has a lot of useful features like tabs, bookmarks, history, website blocking, skins, Bookmark Sync, bookmark import from other browsers, etc.


Note:Newer versions of Google Chrome, Firefox, and Opera are no longer good choices for older computers unless your PC have 3GB or more GB of RAM, a faster multi-core 1.8-2.0 GHZ or faster CPU like a Quad-Core Intel or AMD 64bit CPU, and you have more storage space on your hard drive like 64 GB or more space. It maybe better to use another light web browser like Midori, Web or QtWeb on your older computer. But, Chrome, Firefox, Opera, and other browser makers are always releasing updates for their browsers, so Chrome, Firefox, and Opera may become good choices for your PC in the future.

Google Chrome

Google Chrome which is Google’s official web browser is also worth a try if your computer runs a Linux based operating system, but Google Chrome uses more RAM and CPU resources in Windows. Chrome is not a light web browser for Windows compared to other lightweight web browsers. But, Chrome now uses the Blink instead of Webkit Web Browser engine, so it is more lightweight and faster than before. I have been using Google Chrome as my main web browser in Windows, and it works great since it also has a lot of add-ons, extensions, and it is very stable. It has all the features I need like Bookmarks, history, password manager, and lots of cool themes. It is also updated regularly for improve security, stability and performance because it uses the fast WebKit web browser engine which Apple Safari also uses.



You can also install Chromium which is the open source Blink-based web browser which Google Chrome, SlimJet, Opera, Vivaldi and other web browsers are based on. Ubuntu, Puppy Linux, and other Linux distro operating system makes it easy for you to install Chromium on your computer by searching for it, and agreeing to install it. I use Chromium as my main web browser in Linux, and it is very stable, fast, simple, and feature rich like Google Chrome, and it is updated regularly to fix bugs and improve security. Chromium also uses the Webkit web browser engine.



Opera Web Browser is also faster, and uses the Blink web browser engine like Chrome. It is fast at running HTML5 games and videos, and text and picture based websites and blogs. It also has some add-ons, but not as many compared to Chrome or FireFox. But, it has most of the features you may want like mouse gestures, password manager, bookmarks, history, etc built-in to the browser, and it is also very easy to customize the look and feel of the web browser with themes, or changing the location of the buttons and toolbars.

There is also a free optional VPN for more private and secure web browsing, Battery Saver, Opera Sync, and other useful web browser features in Opera.

Opera will also work on Windows and Linux operating systems like Ubuntu, Puppy Linux, Fedora, Debian, RedHat, OpenSuse, and more.



FireFox also made some improvements in newer versions of Firefox like 10, 11 when it comes to speed, but in my experience it does not run very well unless you have 1GB of RAM in Windows, but it runs better in Linux since it is the default web browser for Ubuntu, and many other Linux Distros. Firefox supports Add-ons, extensions, custom themes, toolbars, bookmarks, history, and more.

It should run pretty good on Linux as long as you don’t install tons of add-ons, toolbars, and plug-ins to Firefox, but in my experience Chromium is a slightly faster web browser in Linux then Firefox.



SeaMonkey which is like Netscape and also made by Mozilla also runs pretty fast on most computers. It supports themes, add-ons, plug-ns as well. It also has an e-mail client and IRC chat built-in. You can also use Sea Monkey to make websites with the WYSIWYG editor. It also supports HTML5, hardware acceleration and improved JavaScript speed.


Green Browser

Green Web Browser which is based on Internet Explorer’s Trident Web Browser engine is a very fast and light resource web browser in my experience. It has most of the features which I need like bookmarks, autofills, password manager, Search, and a lot more. It seems to use the less RAM and CPU Cycles out of all the web browsers which I tried.



Epiphany/Web is a Linux only web browser which runs very quickly even on older Linux computers. It has only the basic features like tabs, navigation bar, html5 support, etc you need to browse the web on a Linux operating system like Ubuntu, Debian, and Linux Mint. Web is created by GNOME which makes the GNOME desktop linux environment. Web is one of the best web browsers for the Raspberry Pi mini PC because it supports video acceleration, so videos on video websites like YouTube run smoother.



Rekonq (2.x) is a lightweight tabbed Window web browser based on the KDE desktop environment, and WebKit Web Browser engine. It is mostly designed for Linux operating systems which use the KDE desktop environment like Kubuntu. Rekonq has features like Bookmarks, HTML5 support, and History.



Konqueror is a Linux tab web browser designed for Linux operating systems which uses the KDE desktop environment. It uses KHTML and WebKit Web layout engine, so it supports modern websites with HTML5, Javascript, CSS3, and other web standards on the site. The web browser also has a bookmark and password manager, spell check, web site translations and more. Konqueror is also a file manager, and viewer app which can view PDF, text files, FTP servers, spreadsheets, etc.



For very slow Linux based computers with a 1GHz or slower CPU, and less than 128MB of RAM, I recommend NetSurf. It just displays text, and images on a website. But, you can’t use it to play online video, music, games, and other more advance tasks. I find loading websites on Netsurf is very fast. It is so lightweight that it can run at a fast speed on a Raspberry Pi mini computer with a slower 700MHz or faster CPU, and 512MB of RAM.



Dillo is another graphical web browser which is mainly designed to display images, and text on a website, but it can’t do more advance tasks like online video, gaming, and using web apps. Dillo runs very quickly on mini computers like the Raspberry Pi.


Microsoft Edge for Windows 10

Microsoft Edge browser which comes pre-installed on Windows 10 is worth a try. You would need to upgrade to Windows 10 from Windows 7 or 8.1 to use Windows 10 on your older Windows 7 and 8.1 computer. Edge runs faster than Internet Explorer 10 and 11 in my experience. It also does not come with a lot of un-needed features which can slow down a web browser. Edge also comes with Adobe Flash player, so you don’t need to manually install Flash. The features on Edge is similar to other desktop tabbed  browser there are tabs, reader mode, note taking app, share, bookmarks, zoom, search, private web browsing, online sync, notifications, password saves, Extension support, PDF reader, and printing. But, Edge does not support ActiveX and other plug-ins which can slow down a web browser. One of the advantages of using Microsoft Edge is that it won’t add extra files and folders to Windows like installing a third-party web browser. If you are using Microsoft Edge on a cheap tablet, laptop, or mini-desktop with 16-32GB of space, you won’t lose additional free space compared to installing a third-party browser which sometimes can use hundreds of MBs of space after you install it on Windows. Edge also gets updated automatically when Windows Update has an update for Edge.

I recommend using Edge browser if you don’t have space to install a more lightweight browser, other lightweight browsers  are not running well on your PC, or websites are displayed broken on your computer when using the browser.

Microsoft Edge is also a mobile web browser, so you can use it in tablet mode on your Windows 10 tablet, and touchscreen laptop computer.

If you need to use an ActiveX, or plug-ins like Java, there is a button in the Microsoft Edge menu settings section to open a website in Internet Explorer which support ActiveX, and plug-ins.

What is your favorite web browser to use on a slower computer?

Tips for making your web browser faster

Using an Alternative Lightweight Operating System to browse the web

If your computer is very slow and old, I recommend you use a lightweight operating system like Puppy Linux, or Lubuntu as your operating system. You can even run Puppy Linux, or Lubuntu on a start-up USB flash drive, or CD/DVD disc if you don’t want to install the operating system on your internal hard drive. In my experience, Lubuntu is pretty easy to install as a dual-boot computer which already has Windows installed on it. Puppy Linux, and Lubuntu are compatible with most of the popular web browsers like Firefox, Midori, Web, and Chrome which all run pretty fast on light weight Linux distro. operating systems. You can also use non-web browsing programs like Libreoffice, VLC media player, Gimp image editor, and play games on Linux based operating systems like Lubuntu.

I read on http://www.neverware.com/ and other Technology Blogs that Cloudready is a fast and easy to use desktop computer operating systems for older computers because it is similar to Chrome OS. You also do not need to buy a Chromebook, or Chromebox to use Cloudready like Chrome OS which can only be used on a Chromebook and Chromebox computer. It is also free for Home users, and $59 for each device for education/school. But, it uses Chromium instead of Chrome as its web browser. Chromium is opensource while Chrome is based on Chromium, but maintained by Google. CloudReady is a lightweight Chromium web browser based operating system which only runs Chromium, and other apps needed to use the internet, and go on the internet. Cloudready does not have as many unwanted apps, programs, and games like other Linux Distros, so it should run faster on older and slower computers. You can also dual-boot CloudReady and Windows 7 and higher on the same storage drive, so you are not stuck with a computer which can only browse the web, but can’t use programs like Photo and video editing programs, games, and video chat programs like Skype which are made for Windows 7 and higher.

Changing your computer usage habits, so you have more free RAM, and a well-maintained PC

I recommend closing unused programs which you don’t need to use anymore will help speed up your computer. If you have other web browsers, word processors, media players, photo editing software, and other software open, you should close them to free up RAM, and CPU Cycles. Having more free RAM, and CPU cycles, will speed up your computer and web browsing experience. Also, make sure your computer is not infected with virus, malware and spyware programs which also slow down your computer. I recommend you scan your computer for malware, virus, and spyware with an anti-virus on a weekly or daily basis.

Restarting your computer can also make your computer less slow.

When using a web browser, close  un-used tabs and windows on your web browser. Uninstalling or disabling unused plug-ins, add-ons, and extensions would also improve the performance of your web browser. Using the default theme might also make your computer feel faster when browsing the web because third-party web browser themes may use more RAM, and CPU resources compared to the default theme for a web browser.

Sometimes uninstalling, and reinstalling your web browser, browser add-on/extensions, and plug-ins to the latest version of your web browser may make it faster.

Also, make sure all your Plug-ins, extensions, and Add-ons for your web browsers are the newest versions. Old Plug-ins, extensions, and add-ons may contain security and stability problems which make your web browser and PC less reliable.

    Chrome based browser are tooooo slowwww ! On my 6 MB+ broadband chrome based browsers loads only 1 page more than 15 sec to be page fully loaded !!! Only 1 computer and nothing interfere with it ! So much for speed of chrome based browsers ! Opera browser has serious NSL and java script problems ! And all browsers are exstensively RAM polluting and choking computer if more than 10 pages opened with java script enabled ! Web developers are miss using java script and no one is doing nothing about it ! There is no java script ID engine for blocking java script that cozes huge RAM polluting and that without flash ! Browsers have no intelligent resource management and equally choking on modern powerful some sort multicore home supercomputer with 16 GB RAM or even more as on P4 x86 with 2 GB RAM or more ! I have tested it ! Internet is no fun any more and browser developer as web page developers have lose all the credibility ! What they develop ? How to get user nerves sky high or what ? Not only that we have to live with crap OS like MS is now browsers and web pages are also crap ! There should be java script identifiying engine to sort out java script problematic web pages and web pages that are overloaded and blocking it ! User experience with internet is getting worse not better ! Web page shoud take ammount of RAM just as same when saved to HDD under 1 MB ! How come that no one is seeing this ???

    I agree with you Steve. Google Chrome, Internet Explorer, and Firefox are using too much RAM even when a few websites are open. Midori, and Flash Peak’s Slimboat web browser seem to run pretty fast on slower computers.

    Web Browser Plug-ins, add-ons/extensions and toolbars may also be slowing down your web browsing speed.

    I notice Java, Javascript, Flash, and shockwave to slow down browsers most.

    I notice using Linux operating systems like Lubuntu, Ubuntu, Linux Mint, and Puppy Linux seems to make web browsing faster, and use less RAM compared to Windows which is slower in my experience.

    Using my Google Nexus 7 with Dolphin Browser, and Boat Browser seems faster than Windows.

    Google chrome is not supported by Pentium 3

  • Johnson Yip November 10, 2014, 5:32 pm

    Thanks Ovais, for informing me that Google Chrome not supporting Pentium 3. You can try other browsers like Midori, Qtweb, and Slimboat which use the webkit browser engine which is the same web browser engine which Google Chrome, and Apple Safari uses for their web browser.

  • Pete Fin June 17, 2015, 4:15 pm

    I have an old Tosh Tecra with half a gig of RAM and running a very early version of XP Pro.
    Frankly I could barely get Midori to work.
    But what is very fast, but only good for limited functions is Crazy Browser.

  • Johnson Yip June 18, 2015, 5:49 pm

    I agree Midori, and other Webkit based web browsers can be slow on systems with less than a gig of RAM when you have many tabs open. I think older versions of K-Meleon which uses the Mozilla Gecko web browser engine may work better.

  • Martin October 10, 2015, 7:46 am

    The better choices for pentium 2 and pentium 3 are firefox 3.5 and google chrome 10 – 33 (optimized versions for mmx and sse with flash versions legacy 10 special). I write for fujitsu lifebook p1120 transmeta crusoe.

  • Johnson Yip October 10, 2015, 6:11 pm

    Thanks for the tip Martin. I agree Firefox 3.5, and older versions of Chrome 10 and up works pretty well on older computers.

  • Steve March 29, 2016, 2:33 am

    I have now 25+ cable internet access and guess what nothing has changed browsers still loading lazy just like on 56k analog dial up access point !!! Browsers are somewhat improved but still problematic ! If i add adblocker i expect browser to working faster and faster loading page but that is not the case ! Without extension one is screwed up by all sort of nasty scripts floating around but with security addons also slowed down and now is not only java script that slows down performance but CSS also ! Seems to me that all of them taking care of forcing us to buy more faster and more expensive hardware all the time and in 1 year there would be performance penalties as somewhat old hardware socket 775 and some AMD counterparts would not be able to run OS and browser to surf the web !!! And we are talking about 8 GB RAM and more and 4 core CPU’s near 3 GHz and browser still choking !!! Single HDD sys cofiguration no mater how fast is not enough any more and we are talking about SATAII/SATAIII one should use SSD and that only the very fast ones !
    For old HDD’s configuration that are still relay able put it in RAID 0 and then and only then one would have decent and enough performance – more than 4 drives in such config does not bring additional performance ! One should take care of monitoring of such configuration and make backup on daily basis ! I use it on P4 3.0+ GHz HT 4 GB RAM on D875PBZ SATA/PATA RAID with win Ready Boost 2×4 GB Patriot sticks each on their own USB controller (one controller 2 USB pair connector) to have max performance, optimized cashe with fast as possible HDD’s and Radeon X1950 pro with 512 MB RAM driven to performance on some fast tweaked Win7 (Slitaz Linux just fly’s so fast outperform Windows unbelievable) ! System performs somewhat fast but some browsers still choking ! Chrome based browsers should be optimized also Firefox to perform faster and web pages should be stripped down not even loading all nasty stuff existed ! The problem is in very small files – performance of the system suffer a lot the more the small files are present and in web pages there a lot of them, the more web pages are open the more strained and throttled system is ! But RAM overflow is now somewhat fixed ! In one or two years from now there would be majority of users on more powerful hardware if they not want to have performance problems in opening 10 pages and then voaila nothing goes more with Windows, Linux is complete different story !

    We are Slaves of progress that is not always user/pocket friendly not to mention electronics waist but newer hardware consumes less power that’s the good news.

  • Johnson Yip March 29, 2016, 4:45 pm

    I agree with your points that more users require faster hardware to browse the web on most websites. I notice a lot of websites now use HTML5 video players, and apps which seem to run slower on older hardware.

    Thanks for the tips on improving the performance of a PC to browse the web faster.
