For some reason, Youtube and other websites won't show up properly. This has never happened before. When I type in Youtube, I can't see it's regular format. But for websites such as Twitter and Google, I get this: https://support.cdn.mozilla.net/media/uploads/images/2013-02-19-08-30-29-2abf53.png ("This conection is untrusted.") I don't know how to take a screenshot, but this appears each time I search in Youtube:

So, who is the issuer of the certificate?

You can't attach a screenshot to the first post that starts a thread, but you can do that in subsequent replies.

Can you attach a screenshot?

  • Use a compressed image type like PNG or JPG to save the screenshot
  • Make sure that you do not exceed the maximum size of 1 MB

The only thing I get about the issuer is this link: http://www.telerik.com/fiddler (Thanks for the screenshot links. I was never sure how to really do it!)
