I have seen the problem with firefox tabs crashing  in the .deb installation and when running direct from the downloaded .tar.bz from Mozilla.
Firefox opens but tabs show error saying "Tab crashed"
This has forced me to use the snap version which works fine though I prefer not to use snaps at all as I dislike the lack of control of them and the restrictions on use that they create
