Yesterday, I wrote about the ”Quick Tabs” feature in IE7 which is not present in Firefox. Of course when I say “not present in Firefox”, I mean not native to Firefox. This functionality can be added through an extension called Firefox Showcase.

This ultra configurable extension offers more functionality than the IE7 Quick Tabs. For example, you can view all tabs in all open windows. To this effect, the extension is almost too configurable (go figure), but is still useful and worthy of an install if you make extensive use of tabs.
