You have asked Iceweasel to connect securely to 1chan.ca, but we can't confirm that your connection is secure.
Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.
What Should I Do?
If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.
This site uses HTTP Strict Transport Security (HSTS) to specify that Iceweasel only connect to it securely. As a result, it is not possible to add an exception for this certificate.
Get me out of here!
