Rated 1 out of 5 stars

I have repeatedly sought to install this dictionary in Thunderbird, never successfully. Though I receive a message that the dictionary was installed, I receive no prompt to restart Thunderbird. When I have restarted, the US dictionary option is the only one which displays. (The dictionary does work with Firefox, but naturally I am more concerned with spell checking my own email.)

This review is for a previous version of the add-on (1.19).
