Rated 5 out of 5 stars

This is simply wonderful, and a perfect companion for Keepass... when it works. Unfortunately I cannot get this to work anymore, since FF4, and onwards this addon just doesn't show anything in the title bar. Very disappointing. UPDATE 23/09/2011 - thanks for the reply bughunter, I've looked into it more and it's obvious you're correct. I've updated my rating. Well done, and thanks for the response.

This review is for a previous version of the add-on (2.0.0.1-signed.1-signed). 

The add-on is actually still working, KeePass can still find the Firefox window and the Firefox window title is still correctly being modified. I'm well aware of why it _seems_ to not work. The user-interface layout has changed substantially in Firefox 4, and the title is never displayed if you are using the new user-interface layout. If you prefer, you can turn back on the old user-interface layout, to see the title being modified, but it's not necessary for password manager utilities such as KeePass to find the Firefox window. You can use the Windows Task Manager (if you're a Windows user) and go to the Applications tab to verify that indeed the Firefox window title is still there, and it's still being modified by the add-on.
