Help me find a way to pause when listening to a youtube lecture on firefox. The ones I prefer run for an hour or more. My laptop allows it but I can't find the way on the iPhone.

Some videos work perfectly fine, however for some videos audio lags behind the video. The same video file perfectly works in Chromium as a control test. Example file is MP4, inside was initially h264 video with AAC audio, for test I re-encoded video to be svt-AV1 with AAC / flac as well - no difference, audio still lags behind. Local players (mpv) and Chromium works perfectly. No plugins which can affect it - for testing disabled them all. I really try hard to like Firefox but this thing is a real bummer. Any ideas what can be causing? P.S. I tested both firefox compiled from source and binary package provided by my distro. Linux system if that matters.

When I am using the android Firefox browser to watch YouTube, it is fine when browsing and finding a video. I will click on a video just fine, and start watching it no problem. The issue occurs when I switch tabs or switch apps to do something else and return later. Once I return to the YouTube tab even if the video is not or was never in full screen, Firefox will then be forced into landscape orientation. This persists between tabs until I either restart the app or do a Google search.

I found a potential solution in these forums. In about:config there should be a setting called media.videocontrols.lock-video-orientation. I tried this, but there is no such setting there for me. I'm at a loss for what to do now.

Whenever I'm watching YouTube and a video goes to the next, it resets back to default setting for the video. Is there a way to fix this? And I've tried to reset my cookies and site data, didn't work.

I've noticed that Youtube videos on Firefox are far more washed out when compared to Google Chrome. HDR is enabled on my Monitor and in Windows 11; however, the issue is present for standard SDR videos as well. Any idea what is going on here?

I've started watching YouTube through my browser and I've begun to notice that it'll automatically change the settings on the site to block autoplay of audio and video, which stops background play.

I have the setting set to allow autoplay audio and video.

I notice it when I switch from the tab and it'll stop playing so I go to the page specific settings and it's switched to block.

How are they doing this? And what can I do to stop it from doing this?

Auto Play. Browser tabs to youtube videos, and maybe others are now playing automatically after update to Firefox 148.0 (64bit).

it was NOT doing this before this Firefox update to 148.0 (64bit).

I am running Windows 11 (64bit).
