Firefox isn't based on Chromium and at this time and looking forward its ability to freely allow users to block ads won't be compromised the way it is (and it'll always get worse) with Chrome and other Chromium based browsers.

Google has been whining about adblockers for years and years and seem to be at the "gun to my head, you better fucking watch these ads!" stage of development. And users said "ok, pull the trigger..." so they are. Or I hope so, but I never underestimate the ability of normie users to open wide for more horse shit to get shoveled down. They'll probably take the increase in ads and barely notice.

But if you care about the ability to block all ads that you want to block without having to jump through whatever loopholes people find, just stick with Firefox.
