[Security] Heads up - mozilla ca certs

[NoOp]

Because it may take awhile for Ubuntu to get around supplying Firefox,
Thunderbird & SeaMonkey updates, I highly recommend that you manually
disable/remove 'DigiNotar Root CA' via your certificate manager. See:

<http://blog.mozilla.com/security/2011/08/29/fraudulent-google-com-certificate/>

For SeaMonkey:
Edit|Preferences|Privacy &
Security|Certificates|Manage Certificates|Authorities|click on
'DigiNotrar Root CA' and click 'Delete or Distrust' & 'OK'.

For Firefox:
Edit|Preferences|Advanced|View Certificates|Authorities|click on
'DigiNotrar Root CA' and click 'Delete or Distrust' & 'OK'.

For Thunderbird:
basically the same as Firefox.

If you are running any of the above directly from Mozilla: Update.
