Great add-on, can be used in a lot of different ways than just dictionary lookup (e.g. look up a bug ID in a bug database, look up a book title or ISBN number on your favorite online bookstore etc. etc.)
This is an absolute must-have for me. Which is why I've been delaying the upgrade to Thunderbird 12 :(
Any chance we can have an updated version soon?
