Crash Data

This bug was filed from the Socorro interface and is
report bp-bed11735-7bb4-4f16-883e-ddc490180816.

This signature is rising on both release and beta: I guessed on where to put this, not sure it belongs in the current component.

All of the users are running Windows 10 and many I looked at were 10.0.17134, which appears to be Redstone 4.

* The crash occurred during the first time I tried opening the Firefox browser after a mandatory Windows 10 update. All other processes on the computer are painfully slow, too. 
* Got the white screen. Computer was on all day, and I was often away from desk, coming back every hour or two and having to bring it from sleep mode and re-do login. After being on for 15 hours I then got white screen. When entering a web address in the address bar, I only got the little whirling circular progress icon.

most likely it's due to windows patch day and we don't have proper symbols yet for ntdll.dll - if we had, i suspect the signatures here fall into our usual shutdownhang candidates.
Adding another similar signature without a bug. This one seems to be all Win 7 crashes. Lots of the same types of comments and crashes started in a similar time frame to this one.
Crash Signature: [@ shutdownhang | ntdll.dll@0x9d7a4] → [@ shutdownhang | ntdll.dll@0x9d7a4] [@ shutdownhang | ntdll.dll@0x6b19a]
Depends on: 1486825
I reprocessed one crash in shutdownhang | ntdll.dll@0x6b19a and the signature translates to [@ shutdownhang | mozilla::dom::quota::QuotaManager::ShutdownObserver::Observe ] ( That bug (Bug 1411908) has a recent comment about filing a new bug for the remaining crashes, which I can do shortly.

The first signature, when reprocessed is [@ shutdownhang | mozilla::SpinEventLoopUntil<T> | mozilla::dom::quota::QuotaManager::ShutdownObserver::Observe ] (, which also appears to be the same Bug 1411908.

I will be filing a new bug shortly to cover these two signatures.
Bug 1487194 was filed to address these 2 signatures.
Is there anything left to do here?

I think we can close this one out. I filed the bug to address the two signatures that are still occurring.
