I have HDR working in Proton games and mpv fine (using Plasma 6.4 / Wayland)

I enabled HDR in Firefox (gfx.wayland.hdr), and HDR content works in YouTube fine ( looks amazing!) however.. I have an issue in that all non HDR content doesn’t show any video (I have sound) just a green sceen (see screen shot) including all ads.

Any idea how to work round this ?

I have AMD 7800 GPU .

Cheers

FINALLY got my zorin os to update, and now also have the newest version of firefox uploaded and working. My singlefile addon works properly, I have upgraded to the newest versions of my video downloaders, and I have cleared my history, but my 2 video downloaders still don't recognize any videos on youtube. Any suggestions or alternative downloaders?

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?

Hi. There is a problem with video playback when skipping through the video using a playback bar. The video (but not audio) freezes at the spot when one skippes to another part of the video and re-establishes after a while (not so short while) to the part of the video that is currently played. I'm using Linux Fedora.

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

Trying to run Prime and Netflix in a Linux browser on my new Lenovo Chromebook Plus 14. Not that this is an ARM based unit (Kompanio Ultra 910).

I can successfully download Firefox for Linux: Mozilla Firefox Debian Package mozilla-deb-1.0 144.0 (aarch64)

But when I go to run streaming video services get: Prime Video is incompatible with your current operating system or web browser. You must update to watch Prime Video titles. Review the Prime Video system requirements. If the problem continues, please contact Amazon Customer Service and refer to error 7132.

Same with Netflix.

any ideas, thoughts, solutions?  :)

Cheers.

For a couple of days now Instagram linked videos won't play here. Actually some of them will -- my own reels and anything linked with that button that looks like a movie 'clapper'. But videos that show the triangular arrow pointing to the right, nothing happens when you click. Not sure if this is a FF issue or maybe something changed at Instagram. Did a google search and nothing came up.

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

Only on firefox, the music on apple music keeps changing volume. I can hear it sound fine for a second but then it changes the volume to around half of what its meant to be. I dont see any settings to change it, its fine on other browsers, im genuinely unsure of 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.

In Firefox, I have audio and video autoplay blocked globally, and added an exception for one particular website (Discord). However, Discord now only autoplays videos once, but doesn't loop them as it should (they implemented GIFs as videos, but now they don't loop).

Of course this could be interpreted as a bug in Discord's web client. However, there shouldn't be a difference between a website that got an exception and autoplay being globally allowed. Therefore i suspect that there is a bug in firefox where some property, state, or hint is set differently depending on whether a page has been added to exceptions or autoplay is allowed globally.

Is there anything i can do to work around this? I really want an autoplay exception to actually work as expected (the website doesn't need to know that it's special)

I am using Firefox on gnome desktop on the PureOS variant of Debian. About three days ago, I went to listen to my Spotify playlist on Firefox, not through the Spotify app. I had no sound, checked my system settings and turned the volume for Firefox from zero back up to normal. The rest of the song played, but when the next song came on, again no sound. I watched the sound settings and when the song finishes, Firefox disappears from the sound settings list. When the next song starts, Firefox is back in the list but volume is set back to zero. I suspect this may be something in gnome, but I thought I would check here in case anyone else is seeing this issue. Thanks so much for any help or at least a shoulder to cry on :D

So Im currently trying to watch young sheldon on netflix, and im doing it through firefox, and it wont work, it says error code f7701-1003, thank you for your time.

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:

For the last two years the issues with video stutter have been worse and worse for me. I don't know if it is because of a different codec the video is using, but if it was I would expect the fans to ramp up from trying to decode it. Instead, my laptop stays always silent, but the video laggs like crazy when I want to play it at native 1440p.

I cannot view or change the video codec, since the current issue happens on a platform (herohero.com) other than youtube.

Hello All,

I noticed that while YouTube videos play with no problems (despite those videos not starting automatically if I open them in a new tab) YouTube Music does not play anything at all. If I open it on my Android Smartphone it works like a charm, but on desktop Firefox nothing.

I'm using Linux Mint 22.3 - Cinnamon 64-bit Kernel 6.17.0-19-generic Desktop Environment: Cinnamon 6.6.7

I installed the ffmpeg codec package Cleared cookies and data for YouTube I did some research on my own and enabled in about:config "media.ffmpeg.vaapi.enabled set to False" Enabled in settings Play DRM protected content Disabled using Hardware acceleration Also PulseAudio is installed

Thank you in advance to anyone who can help me understand what's happening
