Whenever I try to watch a video, on any website, it pixelates so bad that it's just unwatchable. Do I have a setting wrong that could fix this? Watching the same video on different browsers (edge, chrome) works fine. I've attached an image to show what I'm getting. Occasionally, it will work just fine but if I pause the video to come back to it, it goes back to this at some point.

I'm running on windows 11 and Firefox Version 134.0.2 (64-bit)

I am having a problem on Firefox AVC1 and AV1 1080p60 YouTube videos play really bad but VP9 videos play fine only 1080p60 is bad on AVC1 and AV1 720p60 and below are fine i fixed AV1 issue by turning off AV1 now they play as VP9 video 1080p60 is fine but when i force VP9 into AVC1 video that video only shows 360p this issue is only on Firefox i tried same video on Google Chrome it is fine there is there anyway to fix this performance issue

Here is my pc specs

CPU: Intel Core i3-2120 OS: Windows 10 Pro 64-bit GPU: NVIDIA GeForce 210 512MB DDR3 RAM: 6GB

I have two audio outputs I'm trying to use. I want my main output (device A) to stay as the default, but have Firefox play out of the other (device B). There is no option within the browser's settings to change the output device, so I am controlling them through Windows' Volume Mixer. If I set device B as the system default, it works, and it allows me to change Firefox to play from any output. However, if anything else is set as the system default and I set Firefox to play from device B, it doesn't work. It seems like it ignores only specifically that one device, and only when it is set at an app-specific level. It works on all my other outputs no matter which is the default. Even if I have device B as the system default, then at the app-specific level, set FF to any other device, then select device B, it ignores this and continues to play out of whatever device it played from last. The ONLY way I can get Firefox to play audio from device B is with device B as the system default. It's already disappointing that I can't control this directly from FF settings, but the fact that it's also ignoring my OS settings is really frustrating. I've already contacted Windows support, and they say the problem is with Firefox since all my audio devices are working fine. If anyone can tell me a way to just manage this setting properly in Firefox, some way to get Firefox to recognize the device, or some way to allow my windows settings to take priority over whatever FF is trying to do, that would be greatly appreciated. Thanks.

This video file cannot be played.(Error Code: 102630)

I’m getting this error for some reason, and I can’t figure it out. I’ve tried downloading various support files for different codecs, yet I still can’t play videos on websites or live videos like YouTube livestreams.

I’ve tried reinstalling the browser, VLC, and updating the media drivers, but it still doesn’t help. The same videos run fine in other browsers like Edge, but for some reason, they won’t play in Firefox.

Videos on Bluesky have never appeared for me, instead they all say "Your browser does not support the video format. Please try a different browser." This seems to happen regardless of the video source.

I am running MacOSX 11.6.8 and have just recently had my Firefox browser update to version 146.0 and it now has a problem with content playback: whether on video or usic, YouTube or Tidal or any other streaming service, whenever playing back content it stops at 2 minutes and 8 seconds, displays the buffering wheel, and doesnt come back on its own. If I hit pause and then hit play again, it starts playing again fine. But then after 2 minutes and 8 seconds it stops again and I have to restart it again. And again. And again every 2 minutes and 8 seconds. This is a very odd problem, is anyone else experiencing this? It is very annoying.

I am getting sick and tired of ytube video 153 error messages on the latest releases of Firefox when trying to access a ytube video. I use Firefox on Linux (Ubuntu and Mint) with multiple profiles and it didn't used to be this way!!

Even clearing the profile cache and history has unpredictable effect. The web is full of questions to this very issue with no definitive fix. It appears Firefox is not clearing things out properly even though the profile settings are set to delete everything upon exit.

What is the fix?? (or is there one?) A very frustrated longtime user.

I don't get sound on any website, specifically NPR, Kanopy and Youtube. I've tried all of the suggestions in the Help menu, and they were, to put it mildly, no help. This seems to have begun with the latest update (134).

Hi,

I have been having this weird issue that I believe is being caused by firefox as no other internet browser has the same issue. When I'm playing music on spotify and I open firefox the sound goes quite bu the audio is still playing on spotify . One work around I have found is to take on of the tabs and use it to open a new window and the put it back with the others and the sound comes back again. I lost and need help as this is making it hard to want to use firefox which I have been a user of since it first came out.

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
