Extended Statusbar is a Firefox Extension.

You can download it from the developer’s website or the Firefox Add-Ons site.

This extension provides you with the following information in your Firefox Statusbar:

As of version 1.2.5 there are no customizations that you can do to this extension. I’d like to see the ability to show/hide each individual stat. Perhaps in a later release.

Combine this extension with StatusbarEx and you’ve got yourself an information powerhouse!
