Worked find before today, upgraded to 30.0 recently (yesterday, 6/12/14?). Now all google.com and yahoo.com urls fail on firefox (ffx) with error: 

   Secure Connection Failed
   An error occurred during a connection to www.yahoo.com.

or " " www.google.com. or " " accounts.google.com 

   Certificate contains unknown critical extension.
   (Error code: sec_error_unknown_critical_extension)

Problem websites accessible from IE. Tried remove/replace ffx in win7 firewall, no help (NH). Tried clear cache & cookies, NH. All worked fine yesterday -- may not have tried after upgrade to 30.0. Similar environment on win7 home premium x64 laptop with shared ffx sync settings currently works ok.

Chosen solution

After reboot, problem is now cleared. Apparently firewall fix didn't take until system rebooted.
