Today when I went to play spotify on Firefox browser it said playback of protected content is not enaybled and at the top it says "The WidevineCdm plugin has crashed". Ive tried everything I could think of and possibly do.

Ive tried: Restarting my computer Deleting and reinstalling Firefox Using troubleshoot mode Disabling Widevine plugin Refreshing the page Toggling DRM content off then on again and ive submitted all crash reports

Im just not sure what to try next, if anyones experiences this before and has bypassed it somehow. Please share

I have a gpu rtx 50 and recently decided to use rtx super resolution to improve watching online videos but I can't make it work on firefox, I'm currently using the DEV Edition x64 latest version HW Acceleration is enabled and I also tried modifying via about:config the lines: media.peerconnection.video.use_rtx gfx.webrender.overlay-vp-super-resolution gfx.webrender.super-resolution.nvidia

It still doesn't work! tested in the other versions of firefox and it also did not work Using brave, chrome and edge..works normally without having to do anything. Does anyone know what it can be???

I have been looking for any "cast to device" button or setting on and off for a few weeks now and can't seem to find it. Not sure if it's just right out disabled in the browser (because other sites allow me to cast), but YouTube specifically just doesn't have the option anymore. Just wondering if it's something on my end or if it's fixable at all.

Every video i watch is not centered on my screen i tried everything thinking it was on my end but if i try it on chrome and edge everything is fine. Note that only the left and upper side has a space when in full screen the right and bottom are ok In the second image it's on youtube and may appear a bit more clearer

I use Firefox on both my work and home computer as well as my Android phone. I have for years, and until I got a Surface 8 Pro with Windows 11 Home (in case that matters), the behavior across devices was generally consistent, especially after I created a profile and signed into it across all of my devices. Firefox on that device, though, has given me a couple weird differences/issues.

First, I've noticed that the pop-up blocker seems much more "sensitive" on my home computer than on any other devices. A link I click on on my home computer will trigger the pop-up blocker, whereas my work computer will just send me to the link. An example where I see a different behavior is on the Wordle home page: https://www.nytimes.com/games/wordle/index.html. When I click the light bulb at the top on my home computer, the pop-up blocker is triggered, but when I do the same from my work computer, it just goes straight to the link that icon is for.

Now more recently, I've found that sound from a webpage (say YouTube) played on my home computer comes out of the speakers regardless of whether there's a device in the audio jack, which of course my work computer does not do. I've confirmed it's a Firefox problem and not a larger device problem, as other programs output to the audio jack when something is plugged in there just fine.

I've tried resetting my device obviously, and I've even tried doing a Firefox refresh, progressively deleting more and more profile information, and finally uninstalling Firefox completely, removing the Mozilla folder in %APPDATA%, and removing the registry entries that Revo Uninstaller identified, to try to make it as close as possible to the "factory" default, all to no avail.

Whenever I watch any video or listen to music only on Firefox it plays the audio through my mic so when I'm talking online people can hear what I'm listening to If I use the Spotify app it fixes it but I still want to watch YouTube

I'm using Firefox esr, the latest version 149.0.2. Since this update, I can no longer load the videos on NPR.org's home page. Something pops up, but then the wheel/circle thingie just goes round and round, and never loads the video.

My ad blocker was already off for this site. I've tried restarting Firefox in Troubleshooting mode, and changing the various security settings mentioned in this article: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings, such as adding it to the "Allow popups" exceptions (never necessary before) and other settings. I've reloaded the page multiple times, restarted Firefox, etc.

Can anyone suggest anything else to try?

When I try to full screen any streaming site on Firefox I can see the desktop on the edges, the video isn't fully centered on the screen. I have tried updating Firefox, my drivers, restarting my computer and even checking to make sure the resolution and aspect ration were good. Is there maybe an issue or bug I can try and resetting with a setting on the browser?

I've just switched to Fedora 43 KDE plasma from Windows. On Windows, everything was totally find with videos on Firefox. After migration I kept having an error message "The media playback was aborted due to a corruption problem or because the media used features your browser did not support." not only on one site (else it could have been the site). After searching for solution here and on the Net, I found out that it's not related to Fedora but to Firefox when using Radeon RX7700XT on Linux (idem with several distros). And indeed, when installing other browser and testing them there was no problem, even with LibreWolf. So can you please take action as I like Firefox and I would not like to have to move everything to an other browser. And it seems that this problem has been around for at least two years ... which you should be ashamed of.

Hello,

I’m experiencing consistent crashes of the plugin widevinecdm.dll whenever I try to play DRM-protected content (for example, streaming platforms that use Widevine). Every time playback starts, Firefox crashes and the crash reports show errors related to widevinecdm.dll, specifically: EXCEPTION_STACK_BUFFER_OVERRUN FAST_FAIL_CONTROL_INVALID_RETURN_ADDRESS.

In such instances, Firefox keeps working normally. The tab doesn't even crash, it's just the player not responding and the message above telling me that the plugin has crashed. I have already sent multiple crash reports, the last one you can find it here on the Mozilla Crash Stats platform.

Does anyone know how this can be solved? I literally cannot use any subscription service anymore.
