Firefox tabs intermittently missing mute button when opening tab with audio/video. Doesn't matter if its on autoplay allowing audio or if audio is blocked.

Example: When opening kick, twitch, YouTube or any other tab with audio.

Sometimes the mute button will be available, and sometimes its not. If you duplicate the tab without audio sometimes the new duplicated tab will have the mute button.

The first time i noticed this issue is after the most recent update (154.0).

You can right click the tab missing the mute button and mute. The mute button then appears, until you click it to un-mute the tab. It then disappears and the only way to mute again is to right click/mute or type mute in the address bar.
