Recently switched from Chrome to FF on macOS. Running latest Sequoia 15.3.2, Firefox 136.0.2 (aarch64) on a Macbook Air M4.

Problem: When watching a video eg YouTube but including other HTML video, on Firefox where macOS is globally muted and scrubbing through the timeline using the arrow keys, or starting a video mid-way, the audio briefly cuts in (less than a second) and quickly mutes again. I was surprised by this as I expected with macOS globally muted, no application would be able to make any sound.

This behaviour is limited to Firefox and persists with all extensions disabled. macOS is stock with Sound output set to the built-in Macbook Air speakers. No other sound drivers e.g. Soundsource or a USB audio interface have been installed. The laptop itself is brand new and stock.

Can anyone explain why this might be happening?

Hi . I have latest Firefox browser on win11 and from some time i got problems with no sound for my "Eversolo DAC-Z8" . I can play sound thru the browser only on my TV when i set on mixer sound from TV but unfortunaty sound cant go other ways . I dont know what is going on becuse on oldest Firefox browser was no problems .

Videos on Bluesky have never appeared for me, instead they all say "Your browser does not support the video format. Please try a different browser." This seems to happen regardless of the video source.

While watching a video in full screen mode, the screen periodically darkens for 2-3 seconds, after which the video continues, during the darkening the video stops and there is no sound

Hi, I am using Firefox browser on Windows 11, Dell machine with Cirruslogic sound driver There is sound intrruptions when a new music source has started while a music already playing on another tab. While a radio or youtube music stream playing on a tab (in background) and if other tab starts a new sound like youtube or video an any page when started the music background got interrupted (like a small pause operation). If I do the same with chrome or opera, the music goes on without promblem seamlesly. Also if a music stream continues, opening a new music stream on chrome do es not effects. So, the only proble ise with opening sound from different tabs interrups each other on only Firefox browser PS:I am using the Treestyle tab extension. I do not know there is a relation or not Regards Murat
