Some sites won’t work properly with LibreWolf (which is typically when I switch to Firefox), and sometimes LibreWolf has to explicitly ask for my permission before doing certain things on certain sites - which is something I like, but it’s also why I wouldn’t recommend it to an average Joe like my dad, for example.
All those are fine suggestions, but a “free with ads” option isn’t that bad either; the real problem isn’t the ads themselves. The real problem is how intrusive the ads are, how many of them there are, as well as much information they (and YouTube) collect on you. Plus, in this case, the company in question isn’t exactly a small company who is financially struggling. It’s the classic capitalist problem of “infinite growth”, where your profits have to be constantly increasing.
But there’s nothing inherently wrong about the idea of having ads, just like there’s nothing inherently wrong about youtubers having sponsors.
