The part where you are forbidden from using a web browser that isn't Safari (Chrome + FF use Safari under the hood) without jailbreaking the phone?

On my Android phone, I installed Firefox. It synced my extensions and installed uBlock automatically. That was it.

The last time I tried on iOS, I gave up. The adblockers I found didn't really work, they were painful to install, and the platform is so locked down that I couldn't figure out other options.
