Rated 4 out of 5 stars

I found two lines in this add-on that causes most of content of the status bar of Thunderbird 5 to vanish.
The lines
document.getElementById("folderTree").addEventListener("select",acThreadPane,false);
and
document.getElementById("tabmail").addEventListener("load",acMessagePane,true);
in ac-3panewindow.js seem to be responsible for this incompatibility. Removing these lines reduces the functionality of this add-on, but different accounts in the folder pane remain coloured and the status bar is completely visible.
I hope that there will be patched version soon. This add-on is very useful.

This review is for a previous version of the add-on (3.3). 

Version 4.1 is compatible with Thunderbird .5* and 6.*
