There are audio and video files for which I receive in the console that they can't be decoded. Media resource could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_RANGE_ERR (0x806e0069)

I play online bridge (Trickster) twice a week and set up Firefox to share video and sound with my USB mic. (Windows 10 desktop, Trickster opened in Firefox). Most of the time it works fine but occasionally the other bridge players will tell me they can no longer hear me. When I click on the mic icon the message is that Firefox is using the mic. The settings still say that the mic is being shared. Sometimes a windows reset will fix the problem but not always. Can you explain what might be happening.

no matter what website when i put on a video it fades between normal and black constantly i dont know if its my computer im not very good at tech it doesnt happen and never happened on google

When I watch Downton Abbey on PBS from outside the U.S, using the Firefox VPN in a Private Window the Closed Captions of the PBS video are displayed TWICE: one above the timeline and the other above it.

This issue is specific to this particular show AND to the Firefox browser.

Whenever I try to full screen in any streaming websites, it's not full screen at all. There is a little bit of space in the left-side and top-side of the screen where the other windows or applications I have can be seen (or my desktop if nothing else is open). This is not happening to other browsers. Can you please help me to fix this?
