Firefox yes, Thunderbird no Rated 4 out of 5 stars
This add-on works great in Firefox, including Cool Previews windows. It Does Not Work in Thunderbird 3.1, however. They should make this more clear, or better yet, make it work.This review is for a previous version of the add-on (188.8.131.52-signed).
