In Firefox settings: SSL 3.0 is used, no proxy, network.dns.disableIPv6 set to true. The Mac OS firewall has been tested as turned off/on, but still no secure website (e.g. gmail) can be loaded. This happened first after the upgrade to 3.6.6. I then trashed 3.6.6, freshly installed 3.6.10 from scratch, same thing. What a ridiculous glitch... wasted 3 hours on this already. About to move to other browsers after many years on firefox... The whole error message (note the website.... )=========== Secure Connection Failed An error occurred during a connection to support.mozilla.com. Can't connect securely because the SSL protocol has been disabled.
