Simple tweak to make your active tab wider. Using ChromEdit add the following lines to your userChrome.css file: /* Make the active tab wider */ #content tab[selected=”true”] { min-width: 200px !important; } Once you have added these lines, click Save, then Restart; your active tab will be wider than the inactive tabs when Firefox restarts. Notes: You can substitute any value for the ‘200px’. This tweak works for Fx 2 & 3. Tip Source: Eric Wendelin’s Blog

To remove the Bookmark ‘Star’ Button use ChromEdit and add the following lines to your userChrome.css file: /* Remove the Bookmark star */ #star-button { display: none !important; } Once you have added these lines, click Save, then Restart; the ‘Star’ will be gone when Firefox restarts….
