CloseReview for Dictionary Switcher for Thunderbird by Sighurt
Rated 5 out of 5 stars
Great add-on. Very useful, since I write mails both in Dutch and in English. It would be nice though, if it would be possible to give the order in which the dictionaries are checked, because now it chooses US-English while I use UK-English.
Nevertheless I like the extension very much.
