An unwanted scrollbar appears on the right of the toolbar: http://img269.imageshack.us/img269/5194/62078458.png

For the rest it is an amazing add-on! :)

This review is for a previous version of the add-on (0.4.1). 

A workaround

Try to add this code to userChrome.css:

#mail-bar3{
overflow-y: hidden;
}
