I dont know since when this is happening but Firefox is opening alot of processes and every process can appear in my volume settings

If I mute these processes and open a new tab with audio, the mute of the processes will be ignored and audio is playing (most of the time).

Is there a way to bind all the audio to one process again? or any addons to mute everything?


Seems that every time you create a new tab in firefox, then a new volume mixer processor added.

To enable or disable multi-process Firefox, do the following

  1. Type about:config in the browser's address bar
  2. Confirm that you will be careful
  3. Search for browser.tabs.remote.autostart
  4. Double-click on the preference
  5. Set it to False
  6. Do the same for the other browser.tabs.remote.autostart2
