Mozilla lives in the past.

And one would hope they stay there, because all the newer stuff is far more user-hostile.

Could not agree more. I am honestly confused by the need for more than what FF/Librewolf offers and have been actively doing frontend for a long time. Plus no hassle with uBlock. And their Focus mobile browser is nice. I have the same complaints about their leadership as most but at least I feel I have some autonomy with their browser.
