The Installation Instructions are not correct for Thunderbird v 3.1.5 on MAC OS. You have to download the file then go into Thunderbird/Preferences/General/Manage Add-ons Then click on "install" button and select the file.


Have downloaded the British Dictionary but the spellchecker still accepts "meter" and doesn't like "grotty" and accepts program when the UK is programme and it accepts inquiry when the UK spelling is enquiry. So basically it seems to accept US spelling and UK spelling so if you are using it to correct your spelling then it's not really much cop but for me, it's useful to not have UK spellings underlined.

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