The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

I can try to poke.
I have the latest elementary OS 6.0 Odin installed and updated. You can download the iso from https://elementary.io/ by filling in "0" in the custom field. On elementary OS I installed Firefox Nightly from the Ubuntu mozilla daily ppa using the Terminal. I have a Nvidia graphics card installed (GTX1660Ti) and using the 495 driver. I don't know if all these info is meaningfull. If you need to know more, I'm glad to give.
I know elementary OS is using a different Window Manager than other Linux distro's. It uses https://github.com/elementary/gala. My guess is that Gala draws the window background and -moz-window-titlebar isn't working for Gala's background and that's why we see a black square. For this guess I made an issue in github https://github.com/elementary/gala/issues/1342.
On Firefox 94 and before versions, you used the transparent squares in the background for the rounded corners and this was working for elementary OS, but with a userChrome.css styling the rounded corners for the elements above the background. That's why my guess is that -moz-window-titlebar isn't working with Gala.
Oops, I see the window background doesn't have -moz-window-titlebar appearance specified. It is only set with a transparent background... But now I don't know why the background isn't transparent in elementary OS 6.0 Odin. On Firefox 94 it was transparent, but now I updated to 95 and it doesn't show as transparent anymore.
Update:
When I do :root[tabsintitlebar][sizemode="normal"]:not(:-moz-lwtheme) { background-color: rgba(255, 255, 255, 0.5); } the background goes grey. So I know now there is another background under this transparent element. Does Gala renders this black square background or Firefox?

I could repro and am working on a fix btw. We're not detecting the CSD radius properly. It also happens in some GTK3 apps like gnome-tweaks in Fedora with the Elementary theme, fwiw.
Thanks for your reply, it's good to know you're working on a fix!

They style both the parent of the titlebar and the titlebar, which is
a rather odd thing to do, but alas, it works on applications like Gedit
and so on (but not in gnome-tweaks, interestingly).
Relevant code:
Detect this by checking that the headerbar has no radius and the parent
does, and in that case read and render the container frame.
This shouldn't regress any other theme, ideally...
