Corrado is right, but that's a side effect of disabling native wayland support in the firefox snap, thus having it use xwayland, rather than an actual fix to the root cause of the problem. But as Daniel is pointing out, a proper fix is coming.
Note that only the stable channel has been reverted to xwayland, the firefox snap in beta and edge will still do wayland natively. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1964541 Title: Cannot use Drag and Drop in gnome-shell 42 (Wayland session) Status in Mozilla Firefox: New Status in Mutter: Unknown Status in firefox package in Ubuntu: Invalid Status in mutter package in Ubuntu: In Progress Bug description: Since 42~beta-1ubuntu1, and still present in 42~beta-1ubuntu2, attempting to re-arrange tabs in Firefox fails.
