Thanks for answering. It says, when trying to add the Add-On to Thunderbird via the Add-On manager online that it is not compatible with TB 17.0.2. However, when I downloaded it and added it manually as an xpi file all went well and it appears to be working. Not sure why TB gave it a "non compatible" - but it did.
