One comment says: "Right at startup. Works on a clean profile, so I guess the problem is an add-on." I haven't found obvious correlations.
I have the crash when starting a profile with many tabs Here are some tests I performed: 1) Safe mode works. 2) After disabling all extensions in safe mode, regular startup still crashes - this is with a single "restore session tab". 3) After disabling "Use hardware acceleration" in safe mode, regular startup works fine. It works fine even after I enabled all extensions. "Use hardware acceleration" seems to be the culprit, as this is obviously an OpenGL error.
Some of the crash report comments don't crash at startup. It may be due to WebGL use, or the flash plugin using hardware acceleration (isn't that a different process?)
(In reply to Ori Avtalion (salty-horse) from comment #3) > Some of the crash report comments don't crash at startup. Non-startup crashes are not related to this bug.
So, if this is a regression from bug 779019 then shouldn't vlad own this one? I ask because I've been stuck on the nightly from 2012-08-01 due to bug #780232 which is probably this bug...
Should be fixed via bug 779786.
Adding verifyme to confirm that this crash is reproducible before and not after bug 779786 was fixed.
