I would be great if we could get a crash report for this. Not sure if that's possible.

This may just be Clear key, but could indicate a failure with Widevine as well.

Could you confirm that the crash notification shows when navigating to

• Page1 and that the video there won't play?
• Page2 and let me know if the videos on that page do or don't play.

The first case is clearkey, so should be broken due to the crash, the second page is Widevine, and it would be good to know if those are broken too or not.

The Crash notification is shown, but the the video is not broken, can be played end to end without any visible issue.

• Page2 and let me know if the videos on that page do or don't play.

The Crash notification is shown, the video is played, no issue occurred.

Thanks for checking that. This sounds less bad than I had assumed. My worry was this indicated a broader bustage that would also affect Widevine, which doesn't sound like it's happening based on that above.

However, we should still debug what's going on with the clearkey plugin here when there are cycles.

I can confirm that this is fixed by flipping the pref media.gmp-gmpclearkey.allow-x64-plugin-on-arm64 to false, added by bug 1814703. That causes us to launch the ARM clearkey plugin that ships with Firefox instead of the i686 plugin.

This should have been fixed by the landing/uplift of bug 1820669.
