Rated 4 out of 5 stars

It seems to be a very interesting addon but I am getting the error message: [Java script application] Because of a Thunderbird bug, the feature is not available on this platform when I try to save selected messages to PDF. I am running version 78.4.0 (64-bit) on a Mac running Mojave 10.14.6.

This review is for a previous version of the add-on (10.0.1).

unfortunately PDF output 4 does not work on OS X, this is an internal limitation of Thunderbird
have not found a solution yet.
