I'm running the latest version of Firefox on the latest version of Windows 11, and I'm trying to watch TV shows on PBS's Passport service. I get the video but not the sound. It's been like this since Saturday. I don't have this problem at all with Chrome or Edge. Is anyone else having this problem? JT

Hi. Every time I go into youtube, the sound cuts out after about an hour. I then have to go to settings, volume mixer and Mozilla Firefox and click on the X to get the sound back. Youtube has assured me this is not their problem, but a Mozilla one. I've been with Firefox for many many years and have never had this problem. Could you please advise me as to what to do about this ? Thank you.

Weird issue where entire Firefox window flashes grey with a blue box on it

It seems to be related to video playback but not sure. It was happening while a video was playing full screen, and also after stopping playing/hiding a non-full-screen video.

To catch the issue had to screen record at 240fps. I used Nvidia Overlay to record the issue, but was happening before the overlay was even enabled.

Disabled all addons, made no difference. HW acceleration on or off, still happened.


I tried turning on logs, and this always seemed to show up with the flash: ``` 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 ```

Youtube videos are not playing when clicked, it needs a click to play button, which is tiring and wanted to quite firefox if not fixed. When playing youtube videos, where we click on another video, it opens and play for 2 seconds and then it stops, want the user to click the play button to continue, this is unwanted, please make this an option for those you want that feature. I tried to turn it off in autoplay, but there is no options to do so.
