Firefox forcely remove the separator between tabs in new design because users won't open too many tab in general, and they won't make the tab too small to differ. And I fxxking hate it. Because I am the user that will open many tab and make the tab small. So does this mean I should not use firefox because I use it wrong? It's really a shitty attitude if you are exactly the one that they claims 'not-important'. Pray for you not being lucky enough to be the one 'not-important' if you don't know the pain yet.
