Technically, Firefox Focus (a separate browser for iOS) includes an adblocker feature that can be applied system wide via iOS's content blockers subsystem. This was released in the late 2010s.
Firefox including it is likely just reducing the steps required.
Love Firefox. But I always thought it was terribly misguided product direction of them to ever release this as a separate iOS app.
Total speculation, but I wonder if Apple wouldn't approve a single app with all of those features.
If you search the App Store and don’t find it, it’s called Firefox Klar in some markets
Firefox Focus is called Klar (“clear” in German) in Germany because the Focus trademark is owned by a German news magazine.
Wait, it can be used system wide? I copy paste link into Firefox Focus when ads makes a page too unreadable.
Yes and not only that, one can enable that as a safari extension and get an ad-free experience on safari too.
How do you do this? Straight up don’t know what the “content blocker subsystem” is ha
