Rated 2 out of 5 stars

I am afraid that I have to agree with Bob Smith's review. The issue seems to be two-fold. First, many sites do not manage certificates in a manner consistent with Perspectives. Second, Perspectives seems to have problems with their array of notaries, especially mornings EST. In either case, the add-on is not of serious use. I have also uninstalled it.

This review is for a previous version of the add-on (4.2.1-signed).
