I'm trying to stream a show in the firefox browser and I am getting error saying the HLS is not up to date. I've checked my firefox is at the latest update, is this something you need to update on your end?

Facing these issues on video/educational platforms other than YouTube. I am not facing either of these issues on other browsers like Microsoft Edge, on the same network. Please let me peacefully watch my educational videos, else I'll have to switch to other browsers and encourage others to do the same. I have a lot of respect for your open-source community-based browser, but such errors are causing intolerable pain. PLEASE RESOLVE ASAP.

господа,здравствуйте,помогите пожалуйста,любое видео разворачиваю на полный экран на мониторе HDR,а оно тусклое,никак не могу победить эту проблему,я бы отказался от всех остальные браузеров,но вот это единственное что меня останавливает

I have been looking for any "cast to device" button or setting on and off for a few weeks now and can't seem to find it. Not sure if it's just right out disabled in the browser (because other sites allow me to cast), but YouTube specifically just doesn't have the option anymore. Just wondering if it's something on my end or if it's fixable at all.

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.

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?

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).
