Why can I not connect to the Intranet United when I can do it in Internet explore

In the past, I have had no problems to connect to the intranet of the secure site. Now, after that I updated Firefox I get a message indicating that a security problem.
When I go on Internet Explorer, I have no problem connecting to the intranet site for United.

Does the error 'weak Diffie-Hellman ephemeral key? Someone else mentioned get a few weeks on an employee United Web site.

If this is the error you get, the server attempts to use an obsolete encryption encryption algorithm that is vulnerable to the attack of the impasse that was in the news earlier this year.

What does that mean?

Even if you trust the server, a "dead end" attack compromised the security of your individual connection on the server, a lowering of the protection normally provided by SSL to a level that is easily cracked and read by others on the network. This is why Firefox protects you to establish this connection.

What can you do now?

The best solution is to update the server. Please ask for the protection of everyone! However, I suspect this is out of your control and could not happen soon. To work around the problem, you can try to disable these old ciphers in your Firefox, which I hope it will force the server to try some more secure encryption algorithms when connecting with you. Here's how:

(1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

(2) in the search above the list box, type or paste dhe and make a pause so that the list is filtered

(3) double-click the preference security.ssl3.dhe_rsa_aes_128_sha to true to false (disable Firefox to use this encryption)

(4) double click on the security.ssl3.dhe_rsa_aes_256_sha preference from true to false (disable Firefox to use this encryption)

Try again the server; You may need to reload the page using Ctrl + Shift + r to ignore information in cache.

Success?
