What extensions does chrome have which are useful that Firefox doesn’t?
My only recurring issue with Firefox, which may have been fixed I dunno, is it for some reason it “isn’t officially supported” or whatever exact wording to use hardware security keys (like yubikey, which I use on every account that allows it). It’s only certain websites that don’t want to work though. Like google, Microsoft and many others were fine but I think paypal didn’t want to work properly but it does work on Edge, Chrome, probably Brave. Overall annoying as fuck at times but I deal with it to be out of Google’s-world
You can probably get around your paypal problems by telling them your Firefox is Chrome.
