Rated 5 out of 5 stars

It seems like version 0.3 works just fine in Thunderbird 2.0 (when overridden), and the alleged Thunderbird 3.0 is nowhere near completion (there are no even alphas), so it might be actually a good idea to have Thunderbird 2.0 releases enabled again - at users risk. Other than that thanks for this great extension.

This review is for a previous version of the add-on (0.3).
