I can replace the classic tabs list button (the one to the far right of the tab bar) with Tab Previews button for a more graphical, thumbnail-laden tabs list by setting ''browser.allTabs.previews'' to '''true''' in about:config. But is it possible to have both on the tab bar? Or is there an extension that can put one of them on the main toolbar so I can have both? Thank you in advance. P.S.: I'm using Firefox 3.6.17 on Windows XP SP3, in case it matters.
