Hello, I have problem, if I launch FIrefox, it will crash on startup, but if I will reinstall it, it still doesn´t work. Problem has started, when I actualized WIndows. I have Windows 7 and i didn´t experienced crash all time, only this time. It could be launched two days in safe mode, but today it doesn´t work completely. ID of crash is: bp-fadbeea0-a273-45d1-b178-9bc0b2130727

Try to set the gfx.content.azure.enabled pref to false or if this didn't help disable Direct2D by setting the gfx.direct2d.disabled pref to true on the about:config page and leave hardware acceleration otherwise enabled.

That way you still have the benefit from hardware acceleration, but may not suffer from rendering issues.

You can also try to uninstall Windows update KB2670838 if you have this update.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.


Further information can be found in the Troubleshoot Firefox issues caused by malware article.
