Fix error

This article describe how you can solve the problem when you try to navigate from a web address, and in the screen appear this error:

“Firefox can’t connect securely to (site name) because the site uses an older, insecure version of the SSL protocol

Error code: ssl_error_ssl2_disabled”

In Firefox the support for SSL v2 (Secure Sockets Layer 2.0) is disabled by default. While most sites have moved to a better encryption protocol, some have not. If you access a site that only supports SSL v2, you will receive the above error in Firefox.

To fix this error you can turn on SSL v2 support.

SSL v2 is disabled for a reason. It is a flawed security mechanism, and any information you send to an SSL v2 site could be intercepted by someone else.

Follow these steps:

Step 1: In a new tab type about:config in the address bar and press enter;

Step 2: In the filter field enter security.enable_ssl2;

Step 3: Double click the entry so the value is true;

Step 4: Close Firefox and restart;

Another way to fix this problem is this:

Step 1: Go to Tools -> Options -> Advanced ;

Step 2: Choose Encryption tab;

Step 3: Tick both SSL 3.0 and TLS 1.0 boxes;
