Created attachment 458208 [details] Screenshot I have seen the "List All Tabs" button being duplicated a number of times when allTabs preview is activated. Below the "::" button, it also shows the old "\/" button in this case. Here is how I can reliably reproduce this: - set browser.allTabs.previews = true - File => New Window The new window now shows both "::" and "\/" and the tabs become taller (see screenshot). The original window still looks fine. Moving the mouse to hover the extra button makes it go away.
