Komunitné fórum Firefox

I am running Firefox 144.0 on kubuntu 24.04.3 LTS I have lost sound on Firefox. I have opened the same sites in Chrome and the sound is working fine. It's only in Firefox. I have tried several sites including Udemy, YouTube, and radio programs, no sound from Firefox. The problem started in the middle of a Jit.Si session. All of a sudden the sound disappeared. I thought that restart Firefox would help, then restart the computer would help. But the problem has continued. The speakers is turned on the volume is up, just not a sound from Firefox. What to do?

Since Flathub list the org.mozilla.firefox app as official, i hope this is the correct support channel.

Recently i switched from distro specific package managers to flatpak as my application provider. The firefox flatpak won't play most embedded Video/Media on applications like in-browser fediverse clients, forums, blogs or wikis. Youtube works without any issues, Twitch is fine until there is an adbreak. Then it sometimes stops with the supported format/mime error (screenshot appended), only recoverable by cache-dismissive reload.

I used this Article https://support.mozilla.org/en-US/kb/audio-and-video-firefox and the links it contains to debug without any success. None of these samples play. just shows supported format/mime error https://test-videos.co.uk/bigbuckbunny/mp4-h265 At this test website 1. and 3. example won't play. I provided a screenshot before and after trying to click play on all the examples. https://www.tekeye.uk/html/html5-video-test-page

Contrary to the observed behavior about:support#media claims Software Decoding supported for everything except HEVC.

Chromium Flatpak has no such issues. So i copy the video url and play it with chromium. You can see: dire times.

For about 2 weeks now, the audio volume on youtube videos fluctuates up and down. The volume starts off low when a person starts to talk. For example, when the person in the video starts to talk, their voice volume is very low then within a second or two, the volume rises to normal as they talk. When they finish a sentence and start a new one (when there is a short pause in the audio) their voice is again at a very low volume, rising to normal in a second or two. This repeats as they speak throughout the entire video. This is not specific to any youtube video or youtube channel, it happens on all youtube videos. I have tried updating all audio drivers in Windows 11 - no improvement. I have tried rebooting the computer - no improvement Firefox is up to date, version 133.0 I have tried watching the same videos using Chrome and I do not have this problem.

Здравствуйте. При воспроизведении видео на каком либо сайте в полноэкранном виде не скрывается панель задач виндовс. На других браузерах работает как надо. Менял где только можно, даже в безопасном режиме также. Как её можно убрать?

So I'm having a small issue with the volume slider on youtube. The gray bar that indicates volume is about 1% of the size it should be (Please see attached image). It functions fine but bothers me enough that I've contacted support. I've opened it in safe/troubleshooting mode and the issue persists, and there in no issue on chrome. Any help would be appreciated, thanks ^_^.

I recently updated my browser, and I've noticed that while listening to music on YouTube, for some reason, the volume slider within the player also controls the stream volume within KDE Plasma's volume mixer, making for a much more frustrating experience. Now the volume resets to what was set on YOUTUBE rather than sticking to what was set in the VOLUME MIXER every time a new video plays or any time the page refreshes. This means that the volume gets reset every. single. time. The issue with this is not only that YouTube's volume slider isn't as accurate as KDE Plasma's, but also that a media player in a browser shouldn't be controlling its own system volume within the mixer because it causes issues and frustrations like these.

How do I separate player and stream volume?

Here's my inxi so you can see what I'm using/what I'm on: ```text System:

Windows just had an update, in that when I did it now Firefox has no sound at all in Youtube, Disney plus or any other site.

Now I did my own trouble shooting, games have sounds, my music player (winamp) has sound, I downloaded chrome and I oped volume mixer and played a video in that, there was sound.

I do the same thing in firefox and there is no sound, and in volume mixer where the lines go up showing the volume as it plays, it did it for chrome but not Firefox.

So there is no issue with my head set, my computer or my sound, it is firefox alone.

Hi, when I launch a custom video player on a certain site and go into full screen mode, and then want to exit it through ESC, I can’t do it and the picture freezes. I went to the browser console, and it gave me this error: Uncaught (in promise) TypeError: Not in fullscreen mode

   cancelFullScreen https://interneturok.ru/assets/custom-2dc6965f3c367b4e4590249bd2036dfc.js:578
   hotkeys https://interneturok.ru/assets/custom-2dc6965f3c367b4e4590249bd2036dfc.js:675
   dispatcher https://interneturok.ru/assets/custom-2dc6965f3c367b4e4590249bd2036dfc.js:131|

The technical support of that site told me to write to the browser support, I understood the problem is not on their side. I tried everything and went through incognito mode, the problem did not go away. Give me some advice or maybe the problem is with this site and not with the browser, I also tried to launch this video player through Google Chrome and there were no problems there

This is what the GPTchat wrote about the error from the console: Yes, this error is directly related to exiting fullscreen mode. It says that the custom-2dc6965f3c367b4e4590249bd2036dfc.js script on the site is trying to exit fullscreen when the browser thinks it is no longer in it.

That is, Firefox has already exited fullscreen mode, but the player itself "thinks" that it is still there. Therefore, when you press Esc, the script calls cancelFullScreen(), and the browser throws the error "Not in fullscreen mode".

Plus screen Error

Yesterday I updated Firefox to version 115.22.0esr this morning when it was released. Have never had any problems viewing video on Netflix but now I am getting Netflix error message F7702-1003. Yesterday I asked "what can I do? I've rebooted computer as Netflix says and it didn't help."

Today, to see if the issue was a bug with version 115.22.0 esr I logged onto both Peacock and Hoopla to try to stream video. On both sites the same thing happened that happened on Netflix. I log into the site, select a video, and when I try to play it I get a message that "widevineCdm plugin has crashed" and video won't play.

Since this problem just appeared after I updated to version 115.22.0 esr it seems likely that there is a bug in this version which is crashing the plugin and preventing streaming video. I note that I can stream some video having checked both YouTube and an online television station.

Trouble with streaming services(like youtube(only streams ), twitch, music streaming) on nightly Firefox Nightly 145.0a1 (2025-10-11) (x64) Cachy OS Binary from firefox.com

Maybe after update, or i dont know why, but now. when youtube (or any other videoplayer) in fullscreen - taskbar menu is visible (Is on topscreen). In google chrome problem is not repeats. I'm using StartAllBack app for classic start menu, but till that day all was fine. I checked on two devices with firefox - the same problem (StartAllBack or windows version wasnt cahnged). Windows 11 24H2

Good day, I have Firefox 138.0.4 running on Windowx 11 24H2. PC details as follows: CPU = Ryzen 5 2400G RAM = 32GB GPU = RTX 3060Ti 8GB Connection is 50/25Mbps fibre connection

My issue is that when watching F1 from the following site: https://f1tv.formula1.com/, after some time (it differs in how long it takes to manifest), the stream starts to stutter. Note, it is NOT buffering, it is like the stream gets "stuck" or freezes for an instant then continues. The "freeze" then becomes more frequent and sometimes even lasts for about 2 seconds before resuming. The most important fact about all this is that this does NOT happen when using Google Chrome, hence my suspicion that it is somehow related to Firefox specifically. Does anyone have any idea what is causing this and/or how to fix it, please?

Initially connects video playing to Headphones via Bluetooth then audio stops. Reloading doesn't help. But the same works perfectly on other browsers. Problem is with Firefox audio setting. The problem started only a week ago for firefox

This is the link to the video that will not play in FireFox. https://www.swingtechnologies.com/UploadVideos/clarkj@pobox.com/S200629_019 B.mp4

Yesterday my audio on Firefox worked, today it doesn't. I tried all the regular trouble shooting solutions. - My system volume is not 0 - My tabs aren't muted - My headphones are turned on and working fine (audio works everywhere but Firefox) - I uninstalled and reinstalled my Firefox - I uninstalled and reinstalled my headphone audio drivers - Audio also does not work in a private browser, so I know the issue it's related to extensions, cookies, etc. - I had Windows 11 do a quick diagnostic, so the issue isn't Windows 11 related

Usually when this issue occurs, it's as simple as switching from "default" to a specific speaker in volume mixer, but Firefox is not appearing in volume mixer like it did in the past, as shown in the screenshot below.

I don't know what else to do at this point. In previous documentation here, the solution for some people was to wait and it eventually fixed itself, but I'd rather not have audio for weeks to months on end, so has anyone found another solution by chance?

I have Win 11 dell computer that does not play or pick up sound from web sites videos .I checked and tested my sound using the Microsoft platform & buy playing a disc. It works OK

Each time a video call comes in, the message on messenger, says Video calling is not supported on this browser. I've gone to the browser settings and cannot find anything that would change this. Help.

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
