The only currently supported versions are Firefox 6.0 and Firefox 3.6.20.

  • You are using Firefox 5.0 which is no longer supported
  • All other versions of Firefox have security and stability issues that have not and will not be fixed.
  • No responsible volunteer posting here will give you a link to any version other than the 2 supported versions.

Please post a new question with whatever questions you have or problems you are experiencing with Firefox 6 and one of the volunteers here will try to assist you.

I am a student at Penn State. The online course management system used by PSU is supported by versions 3 or 4 only. The tech help desk at PSU informed me that I need to run one of those versions.

If its for just 1 website, use Mozilla Firefox Portable Edition

Install Firefox Portable 3.6.20 to use at that web site. It won't affect your current version of Firefox at all.

Check and tell if its working.
