I tried using the Zoom webapp on Firefox, on X11, for quite a while, but eventually I gave up and started using the native app. The web app is slow and burns CPU (and my laptop fans start going nuts), and for some reason the quality of the video that's coming out of my camera looks much worse on the webapp. (This isn't the case for Google Meet on Firefox, so it's something about Zoom's webapp.)

If I were to switch to Wayland and have to go back to the webapp for Zoom, that would be annoying.
