Rated 5 out of 5 stars

Great program, doing the job that Mozilla themselves should have already done.

The only thing that I will say is I could not find the TOOLS menu for this anywhere, but it's a problem with these horrible new Thunderbird versions. The File/View/Tools/etc menu that you see when you click the main button in the top right is completely SEPARATE from the Menu that's accessed via clicking the ALT key. Really terrible design (not your fault). I suggest you put a message about this in the options window for this add on because I spent an incredibly long time looking for it.

This review is for a previous version of the add-on (4.0.4).
