If you get an unexplained certificate error you should assume that you
are under a man in the middle attack, until you have convinced yourself

Your first highlighted line indicates that the certificate Facebook
presented is not one you have seen previously from them.  The second
highlighted line indicates that you do not have the root certificate
installed for the alleged signer of the that certificate.

You need to obtain that certificate by secure means, convince yourself
that they are reliable and appropriate people to authenticate Facebook
servers, and install it.

Some information on how to install a root certificate that you trust, on
Windows Pidgin, can be found at

You should not rely on mailing lists like this to tell you whether you
can trust any particular certificate as posters here are not
authenticated or vetted.

Thank you for your response.  I have since noticed that the certificate 
expired 2 days ago, which was when the problems started, and the certificate 
hasn't been renewed since.  I have tried to get a new certificate by 
deleting the old one, however this has proven ineffective.  I will continue 
to look for a solution to this problem as it appears to be a Facebook 
certification error.
