no response from notaries... even http://www.networknotary.org/ is down. Wasn't the idea to build a network of notaries that is more reliable than any single https site?This review is for a previous version of the add-on (4.2.1-signed).
I'm sorry that you're having trouble reaching the notaries. It may be that you are behind a proxy that is blocking notary connections.
For another else reading this, I would like to point out that the notaries are not a single site. There are 8 different servers running on a total of 4 different continents.
