I re-tried Firefox couple of weeks ago, in the latest episode of a series of tries to "finally" migrating to it. Same CPU fans blowing like jet engines randomly. None of that with Vivaldi (which is anyway all Chromium/Blink underneath) - so came back to it.

Firefox has so many nice things like containers but basic performance issues are still unresolved.

I think that depends on what sites you are using/things you are doing with it. The only time the fans turn on for me is one specific dashboard in Home Assistant. Nothing else I connect to even moves the needle on temperature/CPU use
