Rated 5 out of 5 stars

Has always been helpful but latest edition seems to have removed the option of Exporting a single message as PDF. Actually there is no way to export a single message at all that I can find. I hope you bring that option back.

Updated: I tried the uninstall/reinstall and it worked! Changed the rating especially for the quick and much appreciated assistance.

This feature have not been removed so probably have to look at specifics. Can you open an issue in the repository so we can track this? If you can identify OS and Thunderbird versions . One thing that has been reported. some people needed to uninstall and reinstall the new version for reason unknown.
