I have just tested the latest nightly on Fedora 35 and it works perfectly for XWayland, however, when running Wayland the bottom corners are still not rounded and the top corners are rounded but still have a weird (barely noticeable unless you know) transparent sharp corner. Note that I am running a [patched version of mutter](https://github.com/yilozt/mutter-rounded) ([RPMs](https://gregor160300.stackstorage.com/s/I4YFXu82ay6mNE0C)) that enables rounded corners in every app, however, Firefox is the only app that breaks the nice uniform look that I believe GTK4/libadwaita are also going for with the rounded corners on all sides (just like Windows 11 and macOS).
I understand that this is an edge case currently (with the patched mutter) but I foresee this becoming a "problem" when in a year or two all other apps also have rounded bottom corners and Firefox is the odd one out, I think fixing this now is a good idea to prevent technical debt.

All firefox windows on Wayland (EDIT: and X11) have a weird black protrusion from the top- left and top-right corners where yaru has curved the window corners, but something from Firefox appears to not be being clipped by the theme. I need to double check whether this appears on X11, but for now consider it Wayland only until I report back, although oSoMoN has checked their system and they don't see the behaviour (on X11). EDIT: I have now checked X11 on my system and I see the same behaviour as described above, so this is affecting BOTH Wayland AND X11 for me.
