Since I updated to Firefox 141.02 I have not been able to play videos on Paramount+ or Netflix. I get an error on the top that says the Widevine plugin has crashed on both streaming services. I have checked that the plugin is on and there are no updates. I am on Ubuntu 24.04. Video on YouTube plays as normal

about audio playing in the background most of the browsers I do use on daily basis. I mostly use for YouTube. Because I can turn off my phone. Save battery life and listen to YouTube in the background. I use brave and Samsung Internet Mostly Samsung internet because I can login into my youtube account with no problem so can you add that in as a feature

Using iOS on Mac Mini desktop, I get no sound on democracynow.org but on the iPhone the sound works fine. Most other streams/videos have fine sound but not imdb.com on the desktop with iOS but again, fine on the iPhone.

Specifically Youtube videos, Youtube music songs and nothing else either never load (95% of the time), load only the first 10 seconds and then buffer or load partially after ~20 minutes. No error messages. Only in Firefox.

I tried: Reinstalling Firefox Switching profiles Disabling all extensions Running in safe mode Clearing site's cache and cookies

It's been like this for a couple of months. Been circumventing it by playing videos in a different browser, but would be nice if there was a fix.

Attached image with a loading screen (lol).

It's a repost btw, posted 2 weeks ago and got 0 views.

[Audio Issue] Firefox Causes Background App Volume Drop on Tab Focus — All Volumes at 100%, Issue Not Present in Portable

Issue Summary: Whenever I focus a Firefox tab (even a blank or safe mode one), the audio volume of background applications (e.g., Spotify) drops or changes audibly. It’s not a ducking effect (as all ducking settings are disabled), and Windows volume mixer shows all apps still at 100%. The issue happens only while Firefox is focused — not minimized, not unfocused.

Reproduction Steps:

Play music using Spotify or another app.

Focus any Firefox window or tab.

Background audio becomes quieter or altered — then returns to normal once Firefox is unfocused. Specifically on focus it will change system volume to 58, then return to what it was previously when unfocused.

System Info:

OS: Windows 11 (fully updated)

Firefox Version: 128.0.2 (issue present since at least 127)

Audio Output: Realtek and NVIDIA High Definition Audio (same issue on both)

Spotify Version: Latest Windows Store version

Windows Sound Settings:

Communications tab: "Do nothing"

All app volumes: 100%

No enhancements or spatial effects enabled

Troubleshooting Already Tried (No Success):

Step Result ✅ Disabled audio ducking in Windows No effect ✅ Disabled audio enhancements No effect ✅ Ran Firefox in Troubleshoot Mode (Safe Mode) Issue persists ✅ Changed Firefox audio backend to winmm via about:config No improvement ✅ Fully reset Firefox profile (about:support → Refresh) Issue persists ✅ Verified with Process Explorer (audiodg.exe shows activity on tab focus) Confirms session change ✅ Ensured all apps in volume mixer show 100% No volume mismatch ✅ Rebooted and tested cleanly Still occurs ✅ Tested Firefox Portable (fresh instance) Issue does NOT occur (portable version behaves as expected)

Additional Notes:

The issue appears to be triggered by the main installed version of Firefox only.

A completely clean portable version does not cause the volume change, suggesting something related to the system-wide install, global config, or registry entries is affecting it.

Even without extensions, without playing any video/audio in Firefox, just focusing the window causes this volume behavior.

What I Plan to Try Next:

Fully uninstall Firefox (including deleting AppData and registry leftovers), then reinstall cleanly to see if that resolves it.

Possibly test Firefox ESR if needed.

Request for Help:

Has anyone experienced Firefox causing audio session or DSP changes on focus, especially with audiodg.exe activity?

Could there be a hidden system-level or registry config that ties Firefox to a shared exclusive audio session?

Any way to trace which audio sessions Firefox creates and how Windows handles them?

Let me know if you'd like logs, about:support data, Process Explorer thread captures, or a video of the issue. I’d appreciate any help from the community in narrowing this down.

Thanks! —Justin

Bug in FireFox ... gives me a blank screen when trying to access this link : https://harrisonburg.org/music_scene/song_list/songs/Werwolves_studio.mp3

Has worked well for years, but with updates you broke it.

No matter what settings I change, I still can't get audio to play from Firefox. I can use other browsers and get audio so I know it’s not my computer. I’ve even tried to uninstall firefox and install the newest version with no luck on getting my audio issue resolved. If anyone has any advice for me, it’d be greatly appreciated

I take guitar lessons on line and the audio for the lessons has suddenly defaulted to muted and I can't unmute it even with repeated attempts. The speaker icon is x-d out. I've rebooted, gone out and back in to the site and tried it on another browser where it worked fine. Firefox is my preferred. What can I do?

After opening a YouTube page and selecting a video to watch, I get a second page with the word DOWNLOADING on it. Sometimes is just another blank page that goes away almost immediately. This happen often.

I went to cp24.com and the video on the right side should load the news channel live automatically but it won't load, I tried downloading a new extension but still does not work, any help would be great, thanks!
