Seems like most developers are way behind with updating their add-ons for Thunderbird 5, and Buttons! is no exception. However, as the extension package format is identical to Firefox, thought I'd give updating the install.rdf file of the xpi package MaxVersion parameter to 5.0 and try installing to see what happened. Seems to work OK!
