I have a Surface Duo 2, I would love to see Firefox support two screened devices and be able to either have a single tab span both screens or to have two tabs side by side in one. I can accomplish this by using multiple browsers now, but would of course prefer to keep my browsing in just Firefox.

More info for the developers here: 

"Dual-screen libraries

Take advantage of our developer and designer resources at including the library of dual-screen layouts that includes: FolableLayout, Snackbar, BottomNavigation, FoldableNavigation, and the latest NavigationRail component.

To see the user experiences possible on foldable devices, download the Dual Screen Experience Example from Google Play (or get the source). "

This would be a great addition. To approximate this I have to have two versions of Firefox (Stable and Beta) installed on my Surface Duo.

It would absolutely be a benefit for other foldables and tablets too.

This feature has been in Edge since Android 11.

Chrome now also has this feature on Android 12.

Firefox is now the only main browser that doesn't support it - it's a deal breaker for dual screen/folding phones - I don't wanna use Edge.

The feature is specifically "open in other window" - which then opens a new instance on the second screen.
