The clipboard does not work on "firefox on wayland". 1. Open "Firefox on Wayland" 2. Copy or cut some content 3. Try to paste it outside "firefox on wayland" on a application like gedit. Expected output: Have the paste Actual output: The clipboard is empty Note that the reverse (from XWayland apps to firefox on wayland) works!
I can confirm this one. Happens for both page content and the address bar.
