Try using your brain... wget "http://mozilla.mirror.ac.za/firefox/releases/3.5.3/win32/en-US/Firefox%20Setup%203.5.3.exe" wine "Firefox Setup 3.5.3.exe" ...install it... (next, next, next...) Now you'll have a shortcut on the desktop. Use it to run Windows Firefox. You might have Linux Firefox installed already so try to differenciate them.
