Firefox

Issue with Firefox:

SSL_ERROR_ACCESS_DENIED_ALERT :-12194 "Peer received a valid certificate, but access was denied."

Solution:

Rather than use individual checkboxes, Firefox now operates over a range of SSL/TLS protocols. These settings are accessed using the about:config preferences editor.

Lowest Acceptable Protocol: **security.tls.version.min** (default SSL3.0 = 0)

Highest Allowed Protocol: **security.tls.version.max** (default TLS1.0 = 1)

To modify:

(1) In a new tab, type or paste **about:config** in the address bar and press Enter. Click the button promising to be careful.

(2) In the Search box above the list, type or paste **tls** and pause while the list is filtered

(3) To disable SSL3 and requires TLS of one flavor or another, double-click**security.tls.version.min** and enter the desired value:


 * 0 = SSL 3.0 okay
 * 1 = at least TLS 1.0
 * 2 = at least TLS 1.1 //See WARNING below//

(4) To disable TLS of one flavor or another, double-click**security.tls.version.max** and enter the desired value:


 * 0 = up to SSL 3.0
 * 1 = up to TLS 1.0
 * 2 = up to TLS 1.1 //See WARNING below//
