I have an old Dell Computer with Windows XP Service Pack 2. If I want to download Firefox, what version will work with my computer?
I understand this is a free download?
All versions of Firefox work on Windows XP. You need to check your hardware specifications.
You can get Firefox 4 from http://www.mozilla.com/ and Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
