It looks like any kind of drag and drop doesn't work in the snap version of Firefox under Wayland session. First I've noticed that I couldn't personalize the toolbar, therefore I've open this bug report: https://bugzilla.mozilla.org/show_bug.cgi?id=1760449 Then I realized also tabs couldn't be moved.
