And still a better experience than chrome with ads, plus I almost never encounter a website with problems
The only real exception I can think of is that Google Meet's audio quality has recently been worse under Firefox than under Safari's. My guess is that the issue is on Google's end (since Firefox used to be fine), or that maybe Safari has access to some special microphone APIs.
For example, the audio in FF outside of Apple sounds real clear and overall great in my experience.
