After upgrading to Fedora 31 I've run into an issue with Firefox, I can
no longer detach a tab from the browser to put it into its own window.
I can drag a tab to another open browser window or to another position
within the same browser window but I can not drag it to a new window by
itself.
If I right click on the tab I can choose move and then move to a new
window, that will work.
Ideas?

Fedora 31 was late to the party. Would have been nice if this was mentioned in firefox release notes.

This seems to be a GTK bug in Wayland implementation [1]:
When there's no consumer of the data the Xorg GTK implementation returns GDK_DRAG_CANCEL_NO_TARGET while Wayland GDK_DRAG_CANCEL_ERROR. Firefox got this as user cancelled the dnd action [2] so it won't move the tab to the new window [3].
Currently I'm trying to figure out with the GTK guys.
