Whenever I play videos on YouTube in Firefox, the video is always choppy and does not run smoothly. I’ve tried restarting the browser and checking my internet connection, but the issue continues. This problem only happens in Firefox, not in other browsers.

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.

Whenever I use Google Meet in the Firefox browser, it works well at first people can hear me. However, for a few seconds, my microphone suddenly cuts out, and I have to raise my voice for it to work again. My microphone remains enabled and does not disconnect when the audio cuts out, but people are still unable to hear me. I have already set my microphone to 'Always Allow' instead of 'Allow Temporarily, but the problem persists.Can anyone help me with this

I need assistance resolving an issue where videos on YouTube play choppily in Firefox. The playback stutters frequently, even at lower resolutions, while other browsers stream smoothly. I’d appreciate guidance on troubleshooting steps to improve video performance—such as checking hardware acceleration, browser settings, or possible extensions causing the issue.

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.

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)

Sound on Rumble. It has always had an Enable Button with a bell, and clicking on that button has always enabled the sound at the videos I watch on Rumble. Recently, clicking on the button, adjusting the sound on Rumble settings in the video, and boosting the sound on my computer do not work. I'm hoping that can be fixed. Thanks in advance.

Issue Description: I’m experiencing a problem with fullscreen mode while using YouTube on Firefox on Windows 11 with a dual-monitor setup. When I enter fullscreen, the video does not cover the entire screen. Instead, I can still see parts of the Windows desktop or background around the edges of the display.

This issue only happens on Firefox and only when using fullscreen mode on one of my monitors. I have already checked my display settings, scaling, alignment, and hardware acceleration, but the problem persists.

System Details:

Windows 11

Dual-monitor setup

Browser: Firefox (latest version)

Issue: Fullscreen video shows borders and does not fully cover the screen

Expected Behavior: The fullscreen video should completely fill the selected monitor without showing any part of the Windows desktop.

Please advise on how to resolve this issue.
