Just install it and use the Select Columns button to choose Sender Mailaddress instead of Sender.

And the 0.0.5 version from the developer's website works with Thunderbird 2.0.0.6.

Thank you, sir, for solving this problem which Mozilla refuses to even acknowledge.

This review is for a previous version of the add-on (0.0.4).

Resolves a long standing issue with TB not showing full email addresses in mail list. Simple and easy to use. More flexible than Show InOut. Unfortunately neither is currently available for 2.0.0.6 yet. Hopefully soon...
