    Aren’t all browsers on IOS simply Safari on a wrapper because Apple are cunts? So is this a Firefox wrapping thing? Or a shitty Apple thing?

      It’s a Firefox Focus for iOS exclusive:

      Firefox Focus is a single-window browser with no tab model. We believe that loading the next document into _self collapses the navigation into the same browsing context that already holds the previous origin, and the race condition then exploits the resulting ambiguity about which origin the committed navigation belongs to. Opening in any other target breaks the origin-inheritance behavior and the attack fails.
