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

I would like to go back to version 3.59. 3.63 is slow and buggy on my unit.

This happened

Every time Firefox opened

I installed new version today

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

But 3.6.3 should run fine. DO you have any add-ons installed, that may be causing the problem?
