My Firefox auto updated to version 158.0 the other morning and since then, the Twitch video player fails to work. I'll try to watch a stream, but the video player will stay black with a constant "buffering" icon. There was no issue the night prior, before my browser updated.

I've tried watching Twitch on another browser and had no issues.

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 am unable to make or receive video calls in Facebook and WhatsApp. I used to be able to in Facebook. The message I get is that my browser doesn't support video calls. What is wrong?

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

Hello Firefox support. I'm having trouble joining meetings in calling applications where I stream my screen from my laptop. I tried several different applications on my Windows 10, and unfortunately, in the Firefox browser, the audio doesn't work at all in various different applications, which reveals that the problem isn't the app. I couldn't find help in Mozilla support, so I'd like to know how I can stream my screen (either full screen or in browser, etc.) along with the audio so that everyone in the meeting can hear the sound of my computer. Thank you.

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.

I am running 155.0.1 latest version at the time of this writing. I am able to log into Netflix, but cannot play content. Part of their trouble shooting was to disable and re-enable DRM (widevine). The problem is that now that I have done so, I cannot get widevine installed again. Is there a manual way to get this installed, clean up what Netflix was so gallant about messing up on my computer? I have seen some old and sketchy posts on redit and other places that suggest ways to do this, but they scare me. I searched the forums here, and didn't see anything that directly affected my question, although I might have missed it.

Thanks all for the help.

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.

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.

in my about:config browser.ipProtection.enabled is messing with my ability to stream music inside and out of FireFox when I go and disable it my music starts working again however after a short time it turns it self back on

When I'm on websites such as Reddit or Facebook, and I'm scrolling down, if I come across more than one post where there is a video, the screen will start to flicker. Only one video will play, but the screen flickers. If there is only one video on the screen, it is fine.

I can turn off Hardware Acceleration and this will resolve the issue, however, when I go to other sites such as Apple TV or GeoGuessr, the sites lag until I turn Hardware Acceleration back on.

The issue seems to be between Hardware Acceleration and when multiple videos are loading on a page.

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

Hi, For a few days while I've been watching content on YouTube and several other streaming platforms, I have noticed that my screen will randomly go completely dark, then slowly fade brightness back up. While it is fading back in, there is an intense grey tint over the whole screen that takes longer to fade away than it takes for the brightness to return to (relatively) normal. This seems to only be happening when I am in full screen, and I truly have no idea what setting or issue could be causing it. At first I thought it was part of a video I was watching, but now that it has happened across quite a few videos and several different streaming platforms, I figure it must be something to do with the browser itself. Sometimes when it goes dark, the screen stays practically black for several seconds before beginning to fade the brightness up, sometimes it is less than one second that it's dark before going grey and fading back up. Interacting with some buttons seems to make it go back to normal, although when I click on settings on a video for example, when I click off of it/close settings, the screen goes back to however grey it was when I opened settings. Sound continues normally the whole time, and the only thing that seems to prevent it from happening is not using full screen, which I don't want to have to resort to, but it has become rather annoying and confusing. Any help is appreciated!

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.

For the past month, out of the blue, I have been unable to play Spotify via my web browser. After troubleshooting with Spotify chat, it seems the issue is actually Firefox, because if I choose to play it via the app installed on my computer, it will play, but not via the web browser.

It was display "Spotify can't play this right now".. then it will skip through three songs, play ads & then will play the first 10 seconds of audio of the next song & then it will cut out.

Anyone else experiencing issues with Spotify via the Firebox web browser?

I'm on a Mac desktop, Mac Tahoe 26.6.2, using the latest version of Firefox, although this frequently happened in previous versions. Audio often disappears from videos and reels. When I refresh the page, nothing happens. To get sounds working again, I have to quit Firefox and restart, but by then I've lost the reels I was watching. This is a big issue for me as I am a musician. Any ideas on how to fix this permanently?
