Review for ImportExportTools by Roemer
Rated 1 out of 5 stars
Only need it for converting individual messages to PDF, and that, in the Dutch version at least, just does nothing. You get the two standard PDF warnings, but no save dialog (like in the other save to actions).
This review is for a previous version of the add-on (3.3.0).To create your own collections, you must have a Mozilla Add-ons account.
