This website doesn't supply identity information
in firefox while browsing gmail.com, I understand that would be because I understand it is required when it needs to load content using HTTP and HTTPS as explained in this post
however when I check most possible scenario to make gmail load contents (from attachment, from profile pictures, loading mails, loading ads, gtalk embedded voice call, hangout), everything is transferred over HTTPS, no HTTP is used
now if I check the fingerprint supplied via the site consumed by Firefox it is
and when I check the identity by using https://www.grc.com/fingerprints.htm, I get different fingerprint
is my understanding correct ? if so why do I see different finger print ?
