Firefox Community Forum

Reposting until I get help from someone. Windows/desktop. On Google Chrome, any streaming website I used with autoplay enabled would KEEP full screen mode ON after changing episodes. It would automatically go to a new page with the following episode and remain full screen. Why doesn't Firefox have this feature?? I'm seriously considering going back to Google Chrome for this one small feature. Every time I had any streaming service playing with autoplay enabled, I didn't have to manually select the full screen option every time. I am having to stand up and manually click full screen function. Every. Single. Time. Somebody please help me if there's a way to active that function.

This started almost a month ago at this point. I had been using Picture in Picture for a while and then I went to watch a new video and noticed the size was messed up.

Default view, the first picture is much larger and if there's anything on the side of the video like playlists, chat or recommended vids, the video will play under it

Theater mode has the video be pretty much the right size

Full screen is pretty much the default view but the rest is black

Sometimes if I wait a while and go back to the tab it'll be fixed but refreshing or changing the size starts it up again.

Did I break something? How do I fix this?

When I play YouTube videos in Firefox, the video stutters and drops frames, even when set to 480p. The audio continues to play normally. This issue does not happen in Chrome on the same laptop.

The problem started about a week ago. I’m using Firefox on Windows 11. Restarting Firefox did not resolve the issue. I’ve attached screenshots for reference.

When I listen to music via Firefox, my computer goes into sleep mode after 15 minutes (windows close and password is required)^)^. I've looked everywhere to find a solution to this problem, but I can't find one... Can you help me?

Started this afternoon, December 27. When viewing Facebook videos, the audio is not working. This is a random event, sometimes the audio will not start with the video, sometimes the video is good, but when the video ends and restarts, the audio doesn't come on. The volume indicator at the top of the Facebook video shows that the audio is on, but there is no sound. Is this a Firefox issue or a Facebook problem?

Particularly on US news sites, inline / spot videos still auto-play despite the FF preference set to block audio and video. Mercifully, audio isn't playing. This seems to be a fairly recent problem since the last couple / few updates; not really certain.

Hi,

How can I force Nightly to play a media type ? Per instance, the top main video here : https://www.lapresse.ca/international/asie-et-oceanie/2025-12-23/coree-du-nord/kim-jong-un-inaugure-un-complexe-hotelier-dans-une-station-de-montagne.php

Best regards iBenny

I am watching videos on you tube and is changing the original language from english to spanish with out me asking and the same goes for the CC subtitles, it keeps on changing the english original to spanish and vice versa and is really annoying, I have no idea if the problem is with Firefox or with Google Youtube!!

I swear this used to be a setting and it vanished or i'm blind. say you open a youtube video in a new tab while staying on your current browsing tab, it used to auto-pause in the background until you navigate to the new tab. I remember being so happy when i found the setting, and it stopped working recently so i went looking for it. it doesn't exist. send help.
