i hate to be that guy, but “works on my machine”. i use firefox on an m1 air all day every day and it runs flawlessly, although it starts chugging a little if i have 20+ tabs open (loaded). but i genuinely cannot remember the last time i’ve seen it crash.
like someone else said, try disabling your extensions, or reinstall firefox on a new user account to try to isolate the issue















can we kindly and respectfully ask sharon to go to a retirement home and pick up knitting or bingo or something and revoke her internet access
