Firefox Isn't Working On Vista?

Question

I wanted to get past some drm videos online with realplayer, but I needed to degrade from Firefox 3 to Firefox 2. I tried to download the videos I needed without success, then I reinstalled Firefox 3. The problem is that its not working and I have tried several times to uninstall and attempt system restores. Firefox 2 and 3 won't open from any icon or start menu at all. How can I fix Firefox 3 on Vista?

Answer 3

1.) Totally Uninstall it (Add / Remove Programs)

2.) Download: ftp://ftp.mozilla.org/pub/mozilla.org/fi...

3.) In Firefox, go Help -> About

If it DOESN'T say Version 3.0.1, it failed.
