Teams, Google Meet, Webex, Zoom -- on Chromium, they all hijack and increase your microphone volume without you knowing. It's infuriating. Just thinking about it pisses me off. You have to have the volume control open and have a live tug-of-war with the app while you're talking.
Firefox, either intentionally or unintentionally, does not let Meet do this. I say Meet, because none of the others work on Firefox anyway.
But the recent Meet update is broken on Firefox, so yeah, there goes that.
