Firefox still supports browsing without tabs It sort of does. I can't open settings in a new window without opening settings in a new tab first and then moving the tab to a new window. Or, create a new window and paste about:preferences into the url bar. Maybe there's some userChrome.css to do it. I can create userChrome.css, which is discouraged, in order to hide the redundant tab bar with the single tab in it. Yes, it sort of works, it's kludgy and has issues.
