Rated 4 out of 5 stars

Very nice add-on, which should be a standard in Thunderbird, so if the developers for Thunderbird 3 are searching for features, this is definitly one!

1 request: can you add support for more languages or put it back on babelzilla (still old version there)?

This review is for a previous version of the add-on (0.9.9.9).
