Wonderful, when it is not outdated Rated 5 out of 5 stars
This is a must have plugin. Unfortunately it takes a while to have a version of the plugin compatible with the latest releases of Thunderbird. Nowadays that we get a new release of Thunderbird very often it is quite frustrating to have this plugin KO most of the time. Would be great to have this basic and very useful feature integrated directly into Thunderbird.This review is for a previous version of the add-on (1.0.5).
