About the addons and stuff breaking, I constantly see posts about this adblock isn't working because Chrome broke something, this addon is no longer updated, google broke this so that addon doesn't work.

well yeah, google has intentionally broken all effective content blockers. that's the fault of chrome. firefox is fine.

firefox will never be able to add built in support for adblocking. reasons include that websites would not just happily drop support for firefox, but some would even put in work to block it entirely! a 3rd party fork can do that, but the main thing can't because of what will follow.

By the way, you seem focused on Firefox, I'm not attacking Firefox,

I'm not focused on firefox, I'm against anything chrome. firefox is not good, its the least bad, but in my eyes there's a large difference between it and chromium. we need more engines.

I'm calling out every browser that needs addons to create a more secure and private browsing experience.

I think having this built in is a very dangerous move for a browser that wants to become popular, and does not want to be blocked by sites.

if all you want is to not need to install anything manually, librewolf has ublock preinstalled.

but I'm not confident about the content blocking abilities of brave. I get that it hides ads, but is that's all it does, or does it also block the resources from loading, tracking scripts from operating? because ublock origin is very effective with that, with its large toolset, if the blocklists utilize them
