Hi I'm on Android 13, oneUI 5.1 Samsung and only have partially working addon, it plays in the background for a few minutes and then will stop, it immediately resumes when I return focus to the firefox tab that the video is playing in, I can see the buffering circle when I come back to the tab almost as if it's refusing to buffer unless I return to the video

Installed Firefox yesterday so it should be the most recent build. Regular ff not the nightly.

Does Firefox's media playback notification appear in these cases?

Nope not a single notification that I've noticed, it seems to happen after exactly 5mins, tried on an older Motorolla phone with Android 10 as well and got similar behavior

With Youtube it's always a bit hard to tell because they could also simply slowly be rolling out a breaking change, but yes, in that case bug 1827583 is the more likely culprit.

Add-ons have no control over

a) Firefox throttling background tabs, or b) Android throttling background Firefox

Any issues in those areas need to be fixed in Firefox itself (and in the worst case, some issues relating to b) might not even be fixable in Firefox itself because they're under exclusive control of Android).

Is this a valuable input to solve the riddle?

If not, how can anybody help with using ADB?

Thanks, that's an interesting clue, although… I still can't reproduce the issue on my phone. I've tested two approximately 11 or 12 minute long videos that according to the page source definitely are "Category: Music" (and from an official artist's channel), and as long as I'm only playing back a single track, everything still worked fine.

(If I try a playlist or leave autoplay enabled, I'm hitting https://bugzilla.mozilla.org/show_bug.cgi?id=1878115, but that's a clear Firefox bug.)

Then we've had the mystery report in issue #45, where the issue supposedly happened even for single videos with definitely no autoplay/playlists involved, and where disabling battery optimisations for Firefox solved the issue, but it remains a mystery why exactly that helped.
