Rated 5 out of 5 stars

I've checked current version (4.0), and it seems that the issues are mentioned earlier have been resolved. I don't see any unnecessary DNS lookups, and all the traffic goes via proxy if it is configured in Firefox.

Requests to Notaries stay non-encrypted, but this probably does not a pose any serious risk.
