Disable DHE

TLS uses several types of key exchange method for securely agreeing on encryption keys. Of the available methods, ephemeral Diffie-Hellman (DHE) key exchange provides forward secrecy. However, DHE parameters chosen by the server cannot be verified by clients (see RFC 7919 for details). In addition, Firefox only requires that the strength of DHE keys is 1023-bits, which - if the server reuses parameters - is potentially vulnerable to the logjam attack.

Users can install this addon to disable DHE-based TLS cipher suites. This could result in websites that rely on those cipher suites becoming unreachable.

2017-04-22   今天，終於找到了原因，因為公司和電信那邊籤的協議，限制了上網的裝置數量，造成的，間歇性，斷網，qq訊息發不出去，不能使用qq快速登入 等問題

，電信的師傅來了後調整了什麼橋接模式，關了限制，就好了。
