Faviconize Tab is a great add-on to have when you have so many tabs open in Firefox that you can no longer see the titles of the pages.
Thanks to this add-on, you can shrink the size of the tabs down to just the icons that represent them.
If you have more than one tab open that you can identify by its icon, you can reduce its dimensions by holding down Alt, Ctrl, or Shift as you click on it.
To return it to its normal size, repeat the step above. With Firefox 2.0, you can save the session with your tabs in either their original or reduced size.
"Close" icon error fixed and tab management improved.
