It would appear that Firefox 121 may have a Mac problem. And not for the first time in FF history.

Twice in two days my cores (on an M1 Max Studio) shot to the top in Activity Monitor, giving neverending beachballs for almost everything. Fortunately, I had a terminal session active that I could get into and kill it.

Assumption was made that I had a bad load, but this morning my wife called down and said her little M1 Mini was stuck with a colored rotating ball. She was in FF, so it was the same thing. Unfortunately, that system required a forced power off restart.

Not a major problem. I loaded an older version for now, but anybody else seeing this?
 
I'm not having that problem but I'm sure we deal with different sites and activity
