@Gargron I've used it since it was Netscape Navigator. I do primarily use Safari now simply because the content blockers are too good but it's a shame it's gone off the deep end.
I think it's a combination of we let web technologies get out of hand making it near impossible for anyone other than a major corporation to develop a successful browser and most people rely on popular brands rather than quality. Mozilla leadership hasn't help in the past either.
I hope they turn their luck around.
