Since Windows XP's end of support, and espicially in 2016 I have noticed that people often say that they have trouble loading web pages and have problems browsing and compatibility issues. As a result of this, I have compiled a list of browsers that work fine on Windows XP, and other info.
- Internet Explorer If you are using Internet Explorer 6/7 get Internet Explorer 8. While it can only load marginally more web pages than IE 6/7 can, it's a lot more stable and faster than both IE 6/7. I'd say you can load 50-60% of web pages with IE 8.
- Firefox The last version that supports Windows XP and Vista was released like, 3 weeks ago, so browsing with Firefox you can load basically everything. You would probably be able to do this until around late 2018, and I reccomend using Firefox on WinXP for this very reason.
- Chrome I think the latest version that supports Windows XP was released some time ago- Around a year i'd guess, so loading web pages won't be too hard. I'd guess around 85-95% of web pages load with Chrome, so Chrome isn't a bad option but certainly isn't the best.
- Netscape Navigator The latest version (That isn't AOL crap) was released in 1998, so it will almost certainly work but good luck loading any web pages at all.
- Opera Latest version supports Windows XP, but I have used Opera in the past (With Windows ME) and it was a bit of pig (no irony intended) to use.
Uncommon/Obscure browsers
- AOL Explorer Rather crap browser discontinued in like 2006 but it's latest version does indeed support Windows XP. I'd say around 75-85% of webpages load in AOL.
- Avant From a quick bit of research, Avant does still support Windows XP. All webpages load in Avant. My second choice after Firefox.
- Safari for Windows No clue.
- Vivaldi Never supported Windows XP and never will.
- Chromium Same situation as Chrome.
- Midori That's for Linux -_.-
- SeaMonkey As of now, version 2.46 supports Windows XP, however version 2.49 will be the last version to support Windows XP. Probably my third choice after Avant.
Hope I helped!
P.S. If I got something wrong, do tell me.
