Adding affected branches. Socorro is flagging this as a startup crash on 64 and 65, but not 66.

Seems like the context is null when we try to create the notification, however I am not sure how that could happen since the context is attached at startup. Jan, do you have any ideas about this scenario ?

Without reproducing or having more information about this crash, the best I can do for now is provide a speculative fix which at the very least should prevent the crash. Hopefully we might be able to find out more on nightly.

I should add, the above logcat came from a user with at least 3 identical reports filed with 0s of uptime -- so this is a startup crash.

Thank you. That confirms my theory regarding how we end up with a null mContext in the agent, but at the same time raises the question what is going on beforehand with onStartCommand being called repeatedly and us eventually and apparently getting an ANR?

Attached file Bug 1516665 - Part 3: Additional logging. r=JanH — Details

Added additional logging. In case the agent is not attached but we are not on a
release or beta build, allow createNotification to be called with a null context
so that we may be able to gather more information from the reports.

Depends on D18115

Ryan suggested respinning Fennec this week for this startup crash. I think that's a good idea as we are still at a 25% update rate for beta. If we can uplift today, I can start another build and we could release 66.0b6 tomorrow or Thursday. Earlier would be better so that we get more crash data this week.

Sorina, can your team do another Fennec signoff?

If yes, steps to reproduce

Unknown

List of other uplifts needed

Hey Liz, we've put checks in code for the build type (if it's nightly, beta or release) so all 3 can be uplifted or ride the train as usual, but only part 1 prevents the crash, that's why I've requested uplift only for it.

Hello, I tried to reproduce this crash on Beta 66.0b6 using multiple scenarios from the crash report(Switching multiple tabs, play some media files, opening different links) and using information received from Vlad but I was not able to reproduce the crash.
Devices:

Samsung Galaxy S8 (Android 8.0);
OnePlus 5T (Android 9);
Google Pixel (Android 9).
