64bit version of Firefox called Waterfox,
https://www.waterfoxproject.org/, built for speed without all the stuff you don't need, then there's Cyberfox,
https://8pecxstudios.com/cyberfox-web-browser, further tweaked for graphics cards either Intel or AMD in both 32bit & 64bit, way better than IE
(hell IE is being dropped by Micro$oft in there new OS Win 10) or the other stuff out there, Opera is now yesterdays news. Comodo Dragon, not bad either, then there's Avant,
http://www.avantbrowser.com/ for the really adventurous
Good luck to everyone, Safe Surfing!
