Today, the team at v12 released a video showing a PoC of Universal Account Takeover affecting Firefox Focus of iOS version.

The video below is demonstration of the vulnerability. We can see that,your X, Google, Reddit, can be taken over only in one click of a link.

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.

Firefox Focus doesn't have tabs on iOS? It does on Android.

Apparently, Focus shipped on Android in single window mode too, but they enabled tabs in 2017.
