Moved to verified.

Thank you


thanx dennis
i have a question-
will i get an answer or a solution in this thread,if not,where can i expect to find it?

Sorry all I know is, if any more info is needed they will post in this Topic or ask you by PM.


firefox 4 was released ,the problem i mentioned still persists.
nothing changed from the original post.
has anyone had that problem ?

HAL crashes are hardware related, so check FF4’s hardware acceleration option, try to turn it of and see it that solves your issue.

already tried that,didnt help
thanx mineria, :frowning:

Try updating your graphics card drivers to the latest available version. Does that help?

i have the latest driver,thats not the problem.
as i mentioned in my original post,something changed in ff 4 beta from 7 to 8,im not sure what it is,but ff 4 beta 7 worked fine with filesystem and registry virtualization and ff 4 beta 8 and all versions after including the final release caused the bsod when i close ff session.
i tried that on a virtual machine as well to exclude the option that something in my system is the cause,it happend again and again.

When it is not related to graphics drivers then I rest my case.
