Rated 4 out of 5 stars

Thank you for your work and your adaptation that replaces very well sidebar contacts.
However, if it was possible, I would really appreciate that, as sidebar contacts, the new message window opens with a double click on the contact name ... It would be absolutely perfect! Thanks again.

This review is for a previous version of the add-on (2.2). 

New version(2.4) is now being checked by mozilla.org, so please wait.
