It's hard to show causation, in general, for anything, but here's a theory.
Mozilla is making decisions to remove power-user features, which is alienating power-users (we've got a whole comment-section of them right here).
This doesn't directly kill marketshare, because there aren't that many power-users. But every time Mozilla alienates another web developer, one less website works in Firefox. When websites stop working right, that's when marketshare really drops.
Also, I'm not convinced the quality of major studio films has dropped as a result of the Marvel era. It just seems that way because 1) we tend to forget the worst films when looking back into the past and 2) Covid really is hurting studio budgets.
