While playing YouTube on firefox I tried to pull down the full screen. Rather going full it stayed same small and rest screen becomes dark . After pulling many times I finally find it full screened. But it happens everytime same after changing video or going back.

I play videos in full screen mode everyday using Firefox. Recently when I move away from the full screen application to a different open window then the taskbar at the bottom of the screen does not appear. I just attempted to duplicate the issue and take some screenshots only to find that if I'm switching to a second Firefox window the taskbar does not show, but if I switch to a file explorer, or Excel Window then it does show. This makes things very difficult because I'm using the Snipping tool to take screenshots, and the Snipping Tool itself allows the taskbar to display.

YouTube videos are playing choppily in Firefox. The video frequently stutters/freezes or does not play smoothly, even when the same videos work normally in another browser. I have restarted Firefox and my device, but the problem continues. I would like help identifying whether the cause is hardware acceleration, Firefox extensions, graphics drivers, or another Firefox setting, and I would appreciate step-by-step troubleshooting instructions.

Whenever there's audio playing, such as in a Youtube video, there's also a faint continuous high pitched noise as well. This issue isn't present in other browsers, is there any way i could fix this?

I can't seem to get microphone and video to work I've checked the permissions and still it's not working. I need to sign a docusign with a notary and time is of the essence . I am about to throw the phone at the wall. please help

so i found a strange problem that when i connect headphones to my computer i have a very quiet sound on firefox videos (youtube an ect.). it is not a low volume on my computer or headphones settings, in other browsers everything works smoothly, i dont know why is is only a problem here in firefox

After a Windows 11 update my Firefox browser no longer has any audio. The sound is turned all the way up in the Sound Mixer and I have no Bluetooth devices connected. After it initially happened I connected my Bluetooth earbuds and it worked for a few minutes before it too lost audio.

I have audio on all my other applications.
