I've been using it for years and not one major problem yet.
I have had difficulties with both firefox and chrome with various programs. Photo editing and the like.
It came down to my ad blocker causing issues.
On photo sites I could view but not edit etc.
The same went for using various functions and add-ons.
Didn't seem to have a rhyme or reason.
Firefox I could edit photos. Chrome I could not based on ad blocker
Go figure
