New version FF3.63 causes a screen faded with script running in the background. I understand that it may not be fully compatible with 64-bit. I was perfectly happy to 3.59 and want to downgrade, is this possible and how?

I would like to revert to the version 3.59. 3.63 is slow and buggy on my unit.

This has happened

Each time Firefox opened

I installed the new version today

User Agent

Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729 .NET CLR 3.0.30729; Media Center PC 6.0)

You can get 3.5.9 here: http://www.mozilla.com/en-US/firefox/all-older.html

But 3.6.3 should work just fine. You have Add-ons installed, which may be the cause of the problem?
