hello, can you try to replicate this behaviour when you launch firefox in safe mode once?

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.
