Secure connection cannot be established
When a website that requires a secure (HTTPS) connection tries to secure communication with your computer, Firefox cross-checks this attempt to make sure that the website certificate and the connection method are actually secure. If Firefox cannot establish a secure connection, it will display a Secure Connection Failed or Did Not Connect: Potential Security Issue error page. Secure Connection Failed
A Secure Connection Failed error page will include a description of the error and a Try Again button. There is no option to add a security exception to bypass this type of error.

Firefox will not open this website (it is my personal photography website.) I'm using Windows 7 64 bit. Seemingly, every other website, but this one will open using Firefox. I have always been able, to use Microsoft's browser, to open this website, except, now, they no longer support W7/64. Thanks, for any help, David Johnson
