It works well with small attachments.
When I got a 10MB attachment in an email, it will cause thunderbird 100% cpu on single core for a while.
Thunderbird will become slow and make me feel it almost got crashed.

By the way, lookout (2011 version) works well without this problem.

This review is for a previous version of the add-on (1.2.17).
