This may be a duplicate, but I really could not find any answer that would work. As the title says, I've been trying to move Firefox tabs from the top to the bottom of the entire window. With this I mean I'd like to move only the tab titles and nothing else (no address bar, ...), and not to move it just below the bookmarks bar. I've been trying and modifying several userChrome.css files that were told to do so (in older versions), but the only thing I could obtain was to move the tab titles below the bookmarks bar, just above the web page. I'm on Arch Linux, using dwm as Window Manager. Is there any way, any css property that could help me? Thanks in advance.
