None of the Mozilla products are working properly anymore in my laptop (Windows 7): Firefox Thunderbird Mozbackup they can start but fail on opeations like restoring bookmarks or reading emails or backing up WHY? Or they sa so incredibly slow, maybe if I leave the PC working overnight, they will respond but I cannot work like that I have updated, reinstalled, diagnosed The worst thing is when they crash and freeze my pc, then when I restart it it makes the loud intermittent bleep or goes to blue screen and tells me that maybe software installation made it fail. Other programmes like google chrome work just fine. Is there a common bug to all the Mozilla products, what is wrong? thanks
