Secure connection failed - Server-Blockade by Firefox
As of Version 34 blocks Firefox insecure SSL sites, because they easily are vulnerable. Instead of the web page the error message that appears is: "Secure connection failed". If you do not know which side you should take the warning seriously. Alternatively, you can bypass the message:
- Enter in the address bar of the browser, the command "about:config".
- Then, you confirm Firefox, "you will be careful."
- After that, you carry in the search box "security.ssl.renego_unrestricted_hosts" a.
- Finally, double-click on the found entry, and then enter in the input field the URL of the blocked page, but without the extra "https://".
