I've tried refreshing the profile, and disabling the extensions with the same result.  I'll try today creating a new profile

I am getting this for the 4th time today. It even crashed while loading crash-stats page while all other tabs were crashed.

1,529 crashes the past 7 days from crash-stats and 717 just the past 3 days.

I suspect a Windows update may be the cause here. I don't know which one as I postponing those on my laptop for 2-3 months. 
These are Windows 7 updates:

I only found 3033890 interesting.

gfbett: What updates were installed around the dates you started crashing in windows 8?

Restored to the point to before the windows updates and I continue to crash.

Verified too, but if I create a new windows user profile, then it doesn't crash.
The current profile on this machine is 4½ years old (cmd: systeminfo | find /i "install date").
I may create a windows user profile and start copying things over until I crash again.

I don't have the update 3033890 since it doesn't apply for windows 8.1. 

I'm not sure when the crashes started, but I think that was around the time a firefox update was pushed (maybe a patch of firefox 37) Since I erased the profile, I don't know for sure that I have all the crashes recorded since the beginning. The earliest that I have (from around 50 crash reports) is from 2015-05-15 with a fresh install of firefox 38.0.1

Nightly started spiking with this crash: 13th of June.
Aurora started spiking with this crash: 30th June - 3th of July. (Firefox 41)

By estimates we'll see another spike once beta hits 10th of August
And then 21st of September spike in release channel.

This was mentioned as a Beta top crash in the channel meeting. Tracked.

Removing FF41 tracking as the original bug 1191889 is FF41+ and fixed.
