Facebook has a weird security certificate

I make use of Twitterfeed to send status updates from my blogs to Twitter and Facebook. In order to send these updates from Twitterfeed (TF), TF must be authenticated to send information to Twitter and Facebook. I went through the process of doing the authentication with Twitter, but when I did the same with Facebook, I received the following warning:

This Connection is Untrusted

You have asked Firefox to connect securely to http://www.facebook.com, 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.

Technical Details

http://www.facebook.com uses an invalid security certificate.

The certificate is only valid for the following names:
  a248.e.akamai.net , *.akamaihd.net 

(Error code: ssl_error_bad_cert_domain)

I Understand the Risks

If you understand what’s going on, you can tell Firefox to start trusting this site’s identification. Even if you trust the site, this error could mean that someone is tampering with your connection.

Don’t add an exception unless you know there’s a good reason why this site doesn’t use trusted identification.

I am not the only one who has encountered this odd security certificate. The WebTips Facebook page also had a remark on it. The question is, of course, why does Facebook have such a weirdly named certificate? Can this be trusted?
