+++ This bug was initially created as a clone of Bug #1257058 +++

Unclear what impact the patch in Bug 1257058 had. But three signatures still topcrashes. With very similar, and somewhat odd history graphs. Note, the increase in crash volume over time can I think be attributed to users updating to version 60

Perhaps we'll be adding shutdownhang | nsThread::Shutdown | nsThreadManager::Shutdown (bug 1526127) as the version 68 equivalent signatures, because the signatures cited so far for this bug are all v60

https://support.mozilla.org/en-US/questions/1273402 google oauth?

Adding signature from bug 1526127

For version 78, only remaining signature is shutdownhang | nsThread::Shutdown | nsThreadManager::Shutdown, and still a topcrash.

Steady crash rate for last 6 months despite multiple password prompts being gone (bug 1606711), although that's not a specific cause it might have contributed to user confusion.

Fortunately version 78 is available from Ubuntu repository since some weeks. The update didn't help. TB still crashes on shutdown, see:

78.7.1 from ubuntu repo shuts down OK for me with no crash. FWIW, home-built daily for me crashes on shutdown at, I would guess, 80% of the time,
but I just started and stopped 78.7.1 at least 6 times with no crash.
But I rarely run the repo verion so maybe it has to be running for a while to crash on shutdown?
