Huh? But I see it says "uBlock Origin" when I install it and the UI looks like what I remember from the full version.

It says "Firefox" when I check the extensions page, so maybe that's where it manages to bring the full version from.

Yes it lets you do it. It doesn’t work.

The webRequest API is key, dns is used, maybe a few more.

Looks like the macOS support has improved but iOS may never happen.
