Firefox mobile supports extensions, including uBlock Origin, there are also some ad-blocking Chromium forks. But I agree, on mobile, there is significant friction, for instance, I don't know any of them that can sync with your Google account. And that's on Android, ad-blocking is even more limited on iOS (ironic considering the business model of Apple vs Google).
