If even tech people (who could easily have multiple browsers around) prefer Chrome over Firefox for minor problems out of convenience, I don't see how Firefox is supposed to really notably gain any market share even if Google completely locks out ad blockers.
I'm one of those dozens too, but sadly, "techies" are not that great at promoting the more open alternatives. Or even ad-blocking in general: just look at how hordes of HN users insist here that everyone who blocks ads is evil and how we have a moral obligation to watch advertising.
Sometimes it’s not “out of convenience” but “we only have the resources to test on one browser and most people use chrome” - so we must cater to that even if chrome is far down the road to enshittification.
