Teams v2 won't use Electron[1]; but for now you can get a small performance boost by just opening Teams using a modern web browser (Edge, Chrome, Firefox) at https://teams.microsoft.com/ -- you can even set up a PWA-type app shortcut.
You can uninstall the client after that. I think there's maybe one feature (popout chat windows) that the client has which you can't get in the browser.
Until recently Firefox releases had all kind of problems (e.g. hardware enumeration)
That's why we recommended Chromium/Chrome for at our faculty for Jitsi usage
I'm a Firefox (beta) user myself, but I would rather try another browser before blaming a webapp -- many issues.
