System: WinXP SP3, Firefox 3.5.7, BitDefender Antivirus 2009
Ever since I installed Firefox, 3 Extensions are disabled on EVERY boot.
I have to use Firefox's Add-ins [Find Updates], witch loads a Compatibility Update. After the required Restart Firefox the 3 Extensions are enabled and remain so unless I reboot.
It appears that BitDefender is undoing the Compatibility Update on each boot 
Any ideas?
And yes, I have posted this problem on a Firefox forum. I also note that other Firefox users report this problem with BitDefender 2010 versions.
