Dear, When playing a video on Youtube, Jellyfin or listening to the radio the video stops after a second of playing. Restarting FireFox works for a short amount of time and after that constant pausing of video's after pressing play. Really annoying.
What I allready tried - What is pressed --> none - Rebooting PC --> 5-10 min fix - Restarting FireFox --> 5-10 min fix - Updating FireFox --> Was on the newest version of 28 OKT 2025 - Updating Windows 11 --> Was on the newest version - Problem Solving Mode (So plugins/addons disabled) --> No fix - Chrome --> Works perfectly - Brave --> Works perfectly
Any idea's/fixes

Speech output for Albanian on the website "loecsen.com" > language course "Albanian". Words cannot be heard under Windows 11. What can I do? I downloaded the Albanian language pack, but the voice isn't there. Is this a Firefox or Windows problem?

My YouTube video just vanished today.
The screen area where the video plays, is blank. Chat starts out then stops.
