Introduced with appr. FF 11/12/13 I experienced very often, nearly reproducible, "This connection is untrusted" messages when trying to connect to 100% trustworthy sites with 100% trustworthy and valid certficates. Sometimes on initial connect, sometimes within a https session. Very often reproducible:

- Connect to https site - fine - connect to whatever http (NOT https) site in another window/tab: fine - switch to first tab window/tab and navigate to different page: "connection is untrusted"

When message appears on first connect: Close FF, restart FF. Maybe several times.

As I've checked my machine with several malware etc. tools available to be sure not to have any trojans or similar sh... on my machine, also traced with sysinternal.com tools the TCP/IP traffic, process activtity etc., I'm sure that my machine is clean.

As now, FF 14.0.1, this DOES NOT happen again, have there been any known issues about this behaviour?

Which security software (firewall, anti-virus) do you have?

Some security software intercept secure connections and send their own certificate.

Some examples are ESET and Bitdefender.

  • ESET setup -> advanced setup -> extend web and email tree -> SSL
  • SSL protocol: Do not scan SSL protocol

Disable Scan SSL in the BitDefender settings.

  • BitDefender -> Privacy settings -> disable Scan SSL
