Firefox Community Forum

This has happened on two different video sites already. While watching a video, it will go extremely dark and happens randomly. I also get a weird blank window frame sporadically. I've unjustly been reporting this to one of the video sites until I noticed the same thing on Youtube.

Youtube videos are not playing when clicked, it needs a click to play button, which is tiring and wanted to quite firefox if not fixed. When playing youtube videos, where we click on another video, it opens and play for 2 seconds and then it stops, want the user to click the play button to continue, this is unwanted, please make this an option for those you want that feature. I tried to turn it off in autoplay, but there is no options to do so.

FF dev 155.0b5 (but this has been ongoing for 1+yr). W11p. Is there somewhere in settings where I can "disable" whatever is blocking videos from being seen? (for example BBC news videos). I have to go to troubleshoot mode to watch. I have previously disabled all potential blocking exts like ghostery & UBlock, but to no effect (still no videos). I have looked in security in settings. Otherwise, I either go to troubleshoot or open chrome. Or, is there an extension that will allow that video viewing? Please advise, thank you.

Firefox tabs intermittently missing mute button when opening tab with audio/video. Doesn't matter if its on autoplay allowing audio or if audio is blocked.

Example: When opening kick, twitch, YouTube or any other tab with audio.

Sometimes the mute button will be available, and sometimes its not. If you duplicate the tab without audio sometimes the new duplicated tab will have the mute button.

The first time i noticed this issue is after the most recent update (154.0).

You can right click the tab missing the mute button and mute. The mute button then appears, until you click it to un-mute the tab. It then disappears and the only way to mute again is to right click/mute or type mute in the address bar.

I was watching some German video (not on YouTube) and needed the subtitles translated into English. The translation itself was great, but as the video went the subtitles were switching from original language to translated, making it almost impossible to read them. The subs are fine when I press 'pause', but pressing it all the time in the moment of a long dialogue for example is inconvinient. I wonder if there's a way I can fix it myself in the browser's settings, or if it's a bug that will be fixed in future updates

When I play YouTube videos in Firefox for Android, the video keeps pausing and buffering constantly. I have tried clearing browser cache and disabling all extensions, but the problem still occurs. My device is Android mobile phone. I hope to get help to fix this playback stuttering issue.

You can write:

YouTube videos are frequently buffering and sometimes play slowly in Firefox, even when my internet connection seems to be working normally. Please help me identify the cause and suggest steps to fix the problem. I would also like to know whether any Firefox settings, extensions, cache, or hardware-acceleration settings could be causing this issue.

Started OBS Vitrual Camera option. in Firefox the camera is no listed.

https://webrtc.github.io/samples/src/content/getusermedia/gum/

only shows phyiscal cams.

How can virtual cameras listed in Firefox?

``` $ v4l2-ctl --list-devices --all OBS Virtual Camera (platform:v4l2loopback-000):

       /dev/video0

SandbergCapture: SandbergCaptur (usb-0000:07:00.0-1):

       /dev/video1
       /dev/video2
       /dev/media0

```

but OBS Virtual Camera is not listed

It was working fine until the day before yesterday. The volume of the speaker got low before it stopped working. The PodCast and Vimeo are working fine. So it is not the problem of my computer speaker.

Tested on OpenSuse Tumbleweed both native & flatpak but also on latest live ubuntu image . After some seconds , with healthy buffer , video pauses/starts with new buffer , until it drops to 480p ignoring the manually 4K setting . When setting manually again to 4K , YT throws error . Blocking av1 and switching to vp9 fixes it . Hardware capable of running av1 (amd , rdna3 , rx 7800t) , local videos or using other chromium based browsers work fine .

title sums it up mostly. I've entered troubleshooting mode; no discernible difference. When I switch profiles the issue is resolved even with the same YouTube account. Tried clearing the cache, nothing. Most recent version of Firefox, windows 11.

Hello I am using Google Flow on my Linux PC and when going to edit scenes I get an error about a missing Codec. If I use Brave browser works fine so this makes me think this is not an OS issue but browser.
