Firefox seems to partially freeze on my new MacMini M1 (2020) running MacOs Big Sur 11.1; I have the latest version of Firefox (84.0). It seems to happen when I log into my mac again after it's gone into sleep / screensaver mode. Firefox isn't completely unresponsive, I can still do some things, but for example: I can't enter text into the search-box, and other parts of Firefox seem unresponsive too (but it's nog 'completely' frozen. Closing and re-opening Firefox fixes it. Anyone else having this problem?
