Starting Firefox( going to Google.Com ) I get either "Secure Connection Not Available" or "Google.com taking to long to load". It is an HTTPS-Only Mode Alert. If I reload the page it goes to Google.com. Also if I create a new tab it works fine. When is says it is taking to long to load it is only loading for a few seconds before I get the message. The problem is only on the initial opening of Firefox. Thanks

The problem is caused by AdBlocker Ultimate. When I disable it everything is fine. What's strange is it only happens on the initial launch of Firefox. Thanks.

You can check the connection settings.

  • Settings -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":
