Review for Gmail S/MIME by Edwilson1989
Rated 5 out of 5 stars
This is an excellent add-on. It allow my contacts to trust the emails that I send them. I had a few problems to begin (which was due to my lack of knowledge) however the authors were extremely helpful and guided me through getting it working.
This review is for a previous version of the add-on (0.3.7).To create your own collections, you must have a Mozilla Add-ons account.
