Bug#756101: iceweasel: Cannot add exception for "sec_error_unknown_issuer"

Hi,

I wrote:

> this also happens with error code sec_error_ca_cert_invalid on our development machines. There is no option to add a security exception. See <http://i.imgur.com/DlFJoUo.png> and <http://i.imgur.com/BCQRuxe.png>. Runnig iceweasel in safe mode did not help. Version 32.0~b5-1 from experimental behaves the same. There's not even a 'Get me out of here!' option. The server does not use HTTP Strict Transport Security.

I just installed Firefox 33.0 Beta 9. It fixes this problem.
