Safari on iOS supports extensions, and - while I don't know - I'd be shocked if Chrome on Android didn't?

Chrome does not.

But we can install alternatives that are better.

You can run Ublock Origin on Kagi's Orion browser on iOS, even though it is webkit.

What about Orion on iOS or Firefox on Android? Both allow extensions

Firefox on Android :)

Brave works if you just want adblock and youtube playback even on iOS!

Then there are the offshoots like Kiwi browser that has the Chrome extension store!

Even Samsung and Edge on Android atleast has Adblock plus that can be enabled but obviously not as good as ublock origin on Firefox.
