And they don't work. I tried uBlock on my IPad Air 2 and no add blocked. PopUpBlocker Strict was also important for me, but also doesn't work. DarkReader seemed to work.

I created a NextDNS account and configured the app, still ads on YouTube in Firefox.

The only two for me that work are Brave and Vivaldi. As I really don't like what Brave does I'll stick with Vivaldi.

iOS is such an uncomfortable and greedy ecosystem...

Edit: Just now I created a piped account and installed Yattee and is it the closest you can get on non-jailbroken iOS?

Here's the configuration https://www.reddit.com/r/Yattee/comments/zedv9x/comment/k2q8p0o/
