Yes have no problem replicating it in safe mode. There seems to be some correlation with how long one presses the mouse button whilst its ocused on the tab . Weird and annoying
Current Firefox versions have a feature called tear-off tabs.
You can detach a tab from the current window and open it in a new window by dragging a tab in the browser window.
You can drag that tab back to the tab bar in the original window to undo that detaching.
