when i MUTE some tabs (using the native FF tab mute icon on the tab) sound is muted for just that tab. HOWEVER, it also mutes ALL SYSTEM sounds.

This occurs both with my regular profile and using a default profile for my version (which has NO ADDONS).

It seems to depend on the type of delivery of the music. (Or something!)

This occurs for the following URLs:

   https://14223.live.streamtheworld.com/WRTI_CLASSICAL.mp3
   https://areena.yle.fi/podcastit/ohjelmat/57-llL6Y4blL

However, rather interestinly, it DOES NOT OCCUR for the "standard" WRTI radio station:

   https://www.wrti.org/classical-playlist-search

it seems UNREASONABLE THAT A WEB SITE SHOULD BE ABLE TO EXERT ANY CONTROL upon system sounds.   So, I must presume this is a FF bug; however, I have not posted it as such (having no confirmation from others).

Hi, Used to be able to play youtube videos on FF. Lately I can't. I downloaded Chrome and it played youtube videos just fine. Can you help me resolve this problem? Thanks, Ed

Firefox just stopped showing the videos in youtube, I can hear the sound but no image, tested with 3 vids , all play normal on chrome sound and picture BUT NOT on firefox, I have cleared cache, updated firefox, rebooted, used CCleaner , cleared history, rebooted PC but to no avail. Are there any settings in Firefox that is preventing screening of utube vids. And how were they changed.? Regards and thanxs Janina

Hello Firefox Support,

I’m encountering a strange issue with Firefox. While playing YouTube videos at very low quality (144p) just to listen to music, my GPU usage spikes to 100%. This happens even when the video is not fullscreen and there’s minimal visual content.

System Info:

   Firefox Version: 140.0.2 (64-bit)

   Operating System: Windows 11 

   CPU: AMD Ryzen 7 8700F (no integrated GPU)

   GPU: AMD Radeon RX 7900 GRE

   GPU Driver Version: AMD Adrenalin 25.6.1 

The issue goes away when I disable hardware acceleration in Firefox settings, but I’d prefer to leave it enabled for better performance elsewhere.

Is this a known issue with AMD GPUs or is there something else I can try to reduce GPU usage during playback?

Thank you for your help.

I found that the sound produced when watching YouTube or any website that uses sound is very small, I tried to compare it with other browsers and Firefox sounds very small when compared to other browsers with the same volume and settings.

Description: while viewing videos on youtube, twitch, odysee (and possibly other sites with videos), the video player may suddenly stop playing, and after that, no video in firefox can be played. Restarting the browser makes this issue disappear for a while, but i'd like a permanent solution.

What i've tried so far: Disabling uBlock Clearing cache and cookies Enabling/Disabling hardware acceleration Disabling proxy extension Disabling antivirus on PC.

YouTube videos encoded at 60 frames per second are extremely choppy in Firefox only. Microsoft Edge plays the same videos perfectly.

I have deleted my profile and reinstalled Firefox, updated graphics driver to the latest version, and toggled hardware acceleration on and off. Nothing helps.

Hi,

Occasionally i get weirdly washed out colors on videos, this seems to mostly happens on my jellyfin instance on high res content. It does not happens on other browser, and the issue is very inconsistent, sometimes disappearing after a reboot, or when refreshing firefox. Same with firefox safe mode sometimes it fixes the issue... and sometimes it doesnt. Disabling or enabling HDR doesnt fix the issue.

I use firefox 141.0b4 and RTX 5070 Ti with the latest driver. Any idea how to fix this? Attached are some screenshots showing the issue

Hi, When I play a YouTube video, there is no sound, then (I'm assuming) there is an update, and the sound returns until the next update, when the sound disappears. I have had everyone try to solve the problem, and even the tech guys don't have an answer, and yes, I get sound from Chrome. Also, when I download a YouTube it plays perfectly fine. Are you able to fix the problem?

I have noticed recently that when i try to play certain videos i am sent that are embedded on webpages the screen just goes black and i cannot see anything but i can still hear the video playing in the background. Why is this happening. I have a new HP envy laptop and am using firefox browser but when i use my work laptop which does not have firefox (IBM Thinkpad) i do not face this issue therefore i assume it is a setting in firefox

Hello. On/about 25jun2025 the sound on my Firefox videos stopped working from any source. I know enough to determine the problem is on Firefox. Videos on MS Edge worked fine. Sound works form VLC songs, etc. Sound does work with earplugs. Wondering if that could have caused the loss of speaker sounds. You think I could delete my current firefox and reinstall it. That would be a pain (an hour or so to set it up again.) Thanks, Bill
