Rated 5 out of 5 stars

Very nice. Opening new tab stuck on 404 Url. I'm able to set new value for tbrowse.backuppage > http://www.google.bom, New Tab function doesn't go there. Always goes to http://www.mozillamessaging.com/en-US/en-us/thunderbird/3.1 --> bla bla 404..

This review is for a previous version of the add-on (3.3.1). 

This is fixed in the next update.
