Firefox Community Forum

Hello, I am hoping someone can help me. I am getting white pixels/lines during youtube play back. There is only ever one at a time. I do not get it every time I watch a video. The lines move with the player if I move the browser.

I have tried: Updating Firefox/drivers Turning Hardware acceleration on/off Setting Firefox to use the dGPU Changing the Optimus mode

I am using Windows 11 and have a Legion 7i Pro Gen 8

I have uploaded an image that shows the line. The line appears in the grass on the right.

Many thanks

When listening to live internet radio, after varying minutes, browser stops and I have to refresh and re-establish link. Does not appear to be related to sleep or desktop display issues. Any suggestions how to correct?

Any time I have another application open and I pause a YouTube video or music everything on my computer mutes. I tried to disable hardware media keys in config but that just mutes my entire browser

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.

MY FIREFOX IS HAVING AUDIO ISSUES. THE VOLUME INCREASES BY ITSELF IT HAPPENS USUALLY IF I ENTER OR EXIT FULL SCREEN MODE, OR IF THE VIDEO OR MOVIE STOPS TO BUFFER FOR A MOMENT IT WILL COME BACK ON AT 3 OR 4 TIMES THE VOLUME. ITS A IRRITATING REGULAR OCCURRENCE. IVE TRIED SETTINGS, AND UPDATES BUT NOTHING SEEMS TO FIX IT. IT SEEMS TO HAPPEN ON ANY WEBSITE I USE. (YOUTUBE, SEVERAL MOVIE WEBSITES AND CARTOON WEBSITES. ITS BEEN GOING ON FOR A COUPLE OF YEARS AND ITS VERY FRUSTRATING. I HAVE TO CONSTANTLY READJUST IT IN AND OUT OF ALMOST EVERYTHING I WATCH. HOW DO I FIX THIS ?

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?

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!

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.

this exact question has been asked last year, none of the suggestions work: I am running Firefox 154.01 on Winux I have lost sound on Firefox. I have opened the same sites in Chromium and the sound is working fine. It's only in Firefox. I have tried several sites including , YouTube, and radio programs, no sound from Firefox. All of a sudden the sound disappeared. The speakers is turned on the volume is up, just not a sound from Firefox. What to do? Right now I had to switch over to Chromium

Hey. Something happen after the last update of the browser. I can se videos online but not hear any sound . I have tried with other browser then i have sound but in firefox i dont have sound . Is this fixable  ???? Kindest gregards Tom

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.

Summary

When using the Spotify Web Player in Firefox, Bluetooth audio devices disconnect whenever the playback position changes (automatic track transition or manual seek). The issue does not occur in Google Chrome or other media applications.

Environment Firefox Version: 153.0.1 (64-bit, Release) Operating System: Windows 11 Home 25H2 (Build 26200) Laptop: Lenovo ThinkPad E14 Gen 5 (AMD Ryzen 5 7530U) Audio Backend: WASAPI Graphics: WebRender Bluetooth Device Tested:

• Google Nest Mini (Bluetooth mode)
• boAt Stone 1010 (same behavior)

Problem Description Spotify Web Player starts playing normally through a Bluetooth audio device.

However, whenever:

• the current song automatically changes to the next track, or
• I manually seek within a song (forward or backward), or
• I manually switch to another track,

the following happens: 1. Spotify continues playing (the progress timer keeps increasing). 2. No audio is heard after the track transition or seek. 3. The Bluetooth device remains connected for approximately 15–18 seconds without receiving audio. 4. After about 15–18 seconds, the Bluetooth device disconnects automatically from Windows.

The Bluetooth disconnection appears to be a consequence of Firefox no longer sending audio after the media transition.

Expected Behavior Audio should continue immediately after:

• automatic track changes,
• manual seeking,
• or switching tracks,

without interrupting the Bluetooth audio stream or disconnecting the Bluetooth device.

Actual Behavior

• Spotify playback timer continues.
• No audio is produced.
• Bluetooth audio stream becomes silent.
• Approximately 15–18 seconds later, the Bluetooth device disconnects.

What I Tested Works correctly

• Spotify Web Player in Google Chrome
• VLC Media Player
• General Windows audio playback

Fails consistently

• Spotify Web Player and youTube web in Firefox 153.0.1

The issue is reproducible with multiple Bluetooth audio devices, indicating it is not specific to a single speaker or headset.

Additional Observations

• Opening other Firefox tabs or using other applications does not disconnect Bluetooth.
• The issue only occurs when Spotify and YouTube changes its audio stream (track transition or seeking).
• Bluetooth remains stable while audio is continuously playing.
• The disconnect only occurs after Firefox stops outputting audio during a track change.

Firefox Information

• Audio Backend: WASAPI
• Graphics Compositing: WebRender
• Hardware acceleration available
• No crashes reported

Steps to Reproduce 1. Connect a Bluetooth speaker or headset to Windows. 2. Open Firefox. 3. Open Spotify Web Player. 4. Start playing music. 5. Wait for the next song to start automatically, or manually seek forward/backward or switch tracks. 6. Observe that audio disappears immediately. 7. After approximately 15–18 seconds, the Bluetooth device disconnects automatically.

Frequency 100% reproducible on my system.

I would like to be able to turn off preload of videos (and images) so that I can watch a page with a lot of videos and only load those that I want to see. This is important if you don't have a high bandwith or a lot of data. I am sure I have done this before but now I am not able to achieve that.

Thank you in advance, Virtually yours, David

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.
