Playlists stopped working

[github-monkey]

For a few weeks now, the add-on has not worked for YouTube, when Firefox is in the background or the screen is off completely.

I have reset Firefox (clear data from Android's app settings) and reinstalled the add-on but the issue continues. Autoplay is on.

Samsung Galaxy Note 10+
Android 12
Firefox 105.2.0

Unfortunately I can't reproduce this issue. Either it's some Youtube change that's only slowly being rolled out and only to some users for now, or else it might be due to the particular combination of Firefox version, Android version and/or particular phone model.

How exactly does the problem manifest itself? Does playback stop immediately after Firefox goes into the background or the screen turns off, or is there some delay?

Playback continues until the end of the video but then does not continue to whatever is supposed to play next, according to autoplay or a playlist. If I forward to the end of the video and the "up next" screen pops up, counting down to the video to be played, even if the countdown is underway, if I then switch to another app or turn off the screen the next video does not start playback. Up until recently, the next video (of a playlist or selected by YouTube with autoplay) would play without issues, with the add-on installed.

Am I misremembering? Does the add-on not facilitate background automatic playback of whatever video is up next? I seem to recall playlists and autoplay in general just working in the background until a few weeks ago.

All the addon can do is to (hopefully successfully [1]) try prevent Youtube from learning that the tab has been backgrounded, but it can't influence whatever Firefox and Android are up to. If Firefox is possibly too aggressive in backgrounding a tab once the video/audio stops playing at the end of a track and/or Android is subsequently too aggressive in throttling or killing background processes, I can't do anything about it.

[1] I just gave it another try with a playlist and for me it's still working fine – while there is a noticeable pause between tracks while in background, playback of the next track always eventually resumes.

Thanks for clarifications and checking. I checked with my Samsung Android 9 tablet, which runs One UI 1.1 and the background playlists work, though it took literally about a minute. My Samsung Android 12 phone with One UI 4.1 does not work.

I have the same issue with my LG v35 (android 10) and on a Motorola g52 (android 12 I think). I have the issue on Firefox and Firefox nightly
On my LG I added Firefox to the battery exception list, so in theory android shouldn't throttle the app, so I guess it might be coming from firefox

I've opened an issue for you under mozilla-mobile/fenix#28311, but if there are any follow-up questions there or anything like that you'll have to get involved yourselves.

Firefox issue now tracked by bug 1812957.

I'm also having this exact issue as a first-time installer of this extension. Youtube videos will continue to play until finished (when in the background), but SOMETIMES will not transition to the next video in the playlist. I tried a bunch of different tests like being in another firefox tab vs having another app open vs having my screen off, trying different playlists I had never loaded on my phone before vs repeats, first song of a playlist vs one in the middle... and couldn't repro it, even though I literally had it happen twice yesterday at random points.

Hi there.

I can confirm something (Redmi Note 13 4G/Android 15/HyperOS 2.2 ~ Latest Mozilla Firefox Nightly for Android):

• When I play any single video (with screen off), I haven't any issue when YouTube tries to automatically play the next suggested video.
• But when I play any video in a specific playlist (YouTube Music), turned off the screen doesn't work, I have to turn on the screen again and manually play the queued video.

Not sure if this addon also works for Spotify web (as a companion for uBlock Origin) because I have a similar behaviour after 2-3 songs.
