Same as bug 810360 for Android, though this time I got a crash report: 46e4fa12-ed7e-4d5c-a061-104222121109 (# pulled out of the profile folder) Playing the HTML5 game on http://lc.clay.io/ eventually crashes the browser after a few levels. I first experienced the crash when installed as a webapp but the same issue is exhibited in the browser proper too.
The crash ID, bp-46e4fa12-ed7e-4d5c-a061-104222121109, is an empty crash signature. I assume it's also an OOM like bug 810360. Can you provide a valid stack trace (see https://developer.mozilla.org/docs/How_to_get_a_stacktrace_with_WinDbg)?
I couldn't replicate the crash with the 11/11 Aurora build but task manager did show memory consumption spiking to 95% at times so its probably the same issue.
retested this app today and had it crash again with the latest Aurora...
We still need a stack trace to know the affected component.
Andrew, does it still happen in the normal mode? in the safe mode (see https://support.mozilla.org/kb/troubleshoot-firefox-issues-using-safe-mode)?
