works for a few mins then stops consistently

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

@buttercookie42 This issue is identical to the following tickets in Bugzilla: https://bugzilla.mozilla.org/show_bug.cgi?id=1827371 and https://bugzilla.mozilla.org/show_bug.cgi?id=1812957 And on top of that there is an issue with media notification on YouTube which is being fixed here: https://bugzilla.mozilla.org/show_bug.cgi?id=1827583

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.

@buttercookie42 Maybe you can change it in the addon to optimize the background playback with the screen off on YouTube. At this time, even if Battery Saver and other battery settings are disabled, some YouTube categories cannot be played in the background with the screen off and the add-on enabled. The next video playback still doesn't work automatically with the screen off, I detailed that in my ticket here: https://bugzilla.mozilla.org/show_bug.cgi?id=1827371

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.
