I really like this add-on, so I'm sorry to report that it actually broke Tb3. I did the usual trick of changing the most recent compatible version in the install.rdf file inside the .xpi file, which is actually an archive. It worked - the add-on became usable - but it also cause all kinds of weird behavior, like being unable to send or save composed messages.
Please fix it so that it works with Tb3!
