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.

I had to get a replacement keyboard,and it worked for a while , And then about a week ago, no volume on you tube,google ,but i have audio on mirosoft edge. Checked volume setting's over several times. An advisor told me ,that the logitech keyboard maker,installed optional driver's , that could have caused this? I searched device manager ,to uninstall but didn't find it?

When playing YouTube videos in fullscreen mode, the video appears to skip as would be expected with frame drops. However, with stats for nerds open on the videos, no frame drops are reported and buffer health is fine (40+ seconds).

I'm on an up to date version of FireFox, I've tried with hardware acceleration both enabled and disabled, I've tried opening task manager to see if system usage looked weird (it doesn't, although it's not like I can have TM running while the video is playing in fullscreen so hard to tell) and am at a complete loss. All drivers for CPU and GPU are verifiably up to date (did full system check three days ago) and the only conclusion I've been able to come to is that it must be either a problem with FireFox or a problem with YouTube. I've seen no recent reports on any of the forums that I can find pointing to either as the culprit. So if anyone has any further ideas or solutions, I'd love to here them.

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.

Respected one, since 2 days ago, the sound was lost when playing video content on platform X. I did not make any changes in the settings for M.F. not even in PC, I HAVEN'T CHANGED ANYTHING FOR MONTHS. Do you have any ideas, advice... Thank You for taking the time to solve my problem.

For a few weeks now, the bluetooth sound drops out or will not connect, the screen freezes and says Firefox is not responding, the screen buffers for a while. V annoying and only when connecting bluetooth sound. Have tried with two different brand speakers, same thing happens. The bluetooth keyboard does not drop out at all, ever. Image is while listening to a TV series on Hulu~

When I play a downloaded video that is in English, my downloaded file plays back in a foreign language, not English. What am I doing to cause this and how can I have the English version only in playback everytime? Thank you so much, being a pensioner I am eager awaiting the ability to donate to you excellent work as often as I like.
