Rated 3 out of 5 stars

I love the idea behind this add-on, but I find that several sites I frequent are giving alarming errors about the certificate not being seen consistently - yet when I look at the detailed notary results it seems perfectly consistent to me. I've googled several times, but not been able to find out the cause of these false positives. I suspect it's a bug.

This review is for a previous version of the add-on (4.5.2.1-signed). 

Hello, thanks for the feedback. This is likely due to several of the default notaries running an older version of the server software, and being unable to keep up with demand. We are actively taking steps to upgrade the notaries and fix this - https://github.com/danwent/Perspectives/wiki/Perspectives-Roadmap
