I've changed to Chrome from Pale Moon (a Firefox fork) after changing to it FROM Firefox because most of my financial sites (US based) seem to be disliking Firefox and any of its forks now. Had issues like that even after removing ad blocker extensions, and when this site also got wonky with Pale Moon about 6 months ago, that was enough. Chrome works perfectly everywhere.
I'm on windows PC, not Mac, so don't know if that makes a huge difference. In fact, I don't know anyone personally who uses a Mac (even my daughter went back to PC), and AFAIK the only poster here other than you who uses a Mac is @BlueRaven. I don't remember any posts from him about site issues, but don't know specifics of his Mac OS version or browser.
There is a Mac tech support forum:
