This situation arises because older, dare I say old, equipment
released with embedded software and using http/https as the
administrative front end were shipped with minimally compliant x-509
certificates.  Often self-signed with 1kb keys and md5 signature
hashes. Not to mention many are past their expiry dates.

However, given the revelations of state sanctioned snooping on network
traffic browsers are being pushed to implement increased compliance
checking for the overall security of users. Firefox is simply
implementing what various 'authorities' are recommending as secure
practices with respect to authentication using pki and x-509
certificates.

The present situation is a PIA.  It could be a lot more user-friendly
if FF so chose. They could have easily allowed one to turn off these
advanced compliance checks for specific IP and DNS addresses so that
the intended benefit remained but the interference with existing
infrastructure was minimised.

But, FF is on its own chosen path to oblivion and the idea of
compromise is totally absent from their project plan.
