Firefox extension to dynamically change superbar icon, similar to Windows Live Messenger

Firefox extension to dynamically change superbar icon, similar to Windows Live Messenger With Windows 7's new superbar, Windows Live Messenger is now able to display your status on the bar's icon (and not on the system tray). So that got me thinking, maybe a Firefox extension could do something similar.

"You could use the ""Windows 7 Gmail Notifier Plus"". It's a standalone application, not a Firefox addon, but it will display the number of unread messages in a taskbar icon.

The thumbnail preview will show you the content of unread messages:

Of course, when you click on it, Gmail will open in the default browser.

EDIT (after changes of the initial question):

WinFox is not an addon as such, more an external application that brings some extended features to Firefox. However, you'll see it changes the taskbar/superbar button with some extra information:

Frequent Items support
Tasks support
Pin support
Auto-detection of the Firefox directory and user profile
FavIcon support (downloads top fifteen favicons to your Firefox Cache directory)
Launch Firefox by clicking on the Winfox icon
Linking of all open Firefox windows – Sets all Firefox windows to use Winfox (only if Winfox is running)
Taskbar progress overlay when downloading files
Number of open tabs illustrated using a taskbar icon overlay
Multiple Firefox profile support"

"I strictly recommend WebMail Notifier addon for Firefox.

WebMail Notifier checks your webmail accounts and notifies the number of unread emails.
You can use multiple accounts in a same host.

Currently supports
- mail.google.com (Gmail & Google Apps)
- mail.yahoo.com (yahoo.com, ymail.com, rocketmail.com, yahoo.co.jp)
- mail.live.com (hotmail.com, msn.com, live.com)
- www.daum.net (hanmail)
- www.naver.com
- www.nate.com (nate.com, empas.com)"
