The secure connection feature on Firefox checks to make sure the website certificate and the connection method are secure when users are attempting to access a site. If the browser identifies an issue and if Firefox cannot establish a secure connection, users will see an error message. The secure connection failed error could be the result of unsupported TLS version or incorrect system date. Since there could be different reasons why the error occurred, it is best that you call the Mozilla Firefox support number to implement the correct solution.
