There was a hint that with one of those Crash Signatures using the Sleep function could be a problem so if you normally use that function try without doing so and see if it improves at all.

I am afraid I did not see anything helpful to me in those Crash Signatures None of those were in safe mode, so it would be worth trying with plugins disabled and in Firefox's safe mode

• Does that reduce the frequency of crashes ?
  • And could you post a couple of Crash IDs from such crashes.

It may produce a different crash signature that may be of more help in troubleshooting. I am afraid I am clutching at straws rather with this but it is probably also worth checking for malware using all the tools mentioned in this article

     Bug 1112741 - crash in js::types::TypeObject::maybeSweep(js::types::AutoClearTypeInferenceStateOnOOM*)

After making sure that: McAfee is disabled, Graphics drivers are up to date, SFC didn't find anything, 3 different malware scanners didn't find anything (ESET, McAfee, AdwCleaner),

I'm using same plugin setup on 3 machines. Only my main one is giving me problems. On windows 7, 8 and 8.1 everything was ok. Crashes started after Windows 10 update. I even made a fresh windows installation. i will try to catch one crash in safe mode.

Ok. So it's probably the "sweep" function. But i don't know what it is. Maybe it's somehow related to touchpad gestures. So what do i do now? How do i turn it off? What can i try next?

OOM (OutOfMemory) is also shown. Some Win 10 users have been having issues.

I've called for more help.
