Great! Just some ideas... Rated 5 out of 5 stars

Works well. Add the "faviconize tabs" and the "Delete Add Tab button" extensions, use the "Compact Classic" theme and you'll be amazed how many tabs you can fit up there. My netbook's resolution is 1024x600 and I can fit about 30 tabs in one line!

Now the ideas...

For those of us who like to use our mouse rather than the keyboard, it might be a good idea to add the option of replacing the default "firefox" button with a much smaller one.

Now, the last obstacles to "ultimate tab space optimization" are the minimize, full screen, and exit button! Can these be removed too?

Thank you for this extension
