修复您的连接不安全错误：(Fix Your Connection is not Secure Error: )Mozilla Firefox是一种广泛使用的网络浏览器，它是有史以来最受信任的网络浏览器之一。Mozilla Firefox 会验证网站证书的有效性，(Mozilla Firefox verifies the validity of website certificates)以确保用户访问的是安全网站。它还检查网站的加密是否足够强大，以便维护用户隐私。当证书无效或加密不强时会出现问题，然后浏览器将开始显示错误“您的连接不安全(Your Connection is Not Secure)”。
在大多数情况下，问题可能与Firefox有关，但有时问题也可能存在于用户 PC 上。如果您遇到上述错误信息，您只需单击“返回(Go Back)”按钮，但您将无法访问该网站。另一种方法是通过覆盖警告继续访问该网站，但这意味着您将您的计算机置于危险之中。
为什么您面临“您的连接不安全”错误？(Why you’re facing the “Your Connection is not Secure” error?)
您的 Connection is Not Secure错误通常与与SSL（安全套接字层）相关的(Secure Socket Layers)SEC_ERROR_UNKNOWN_ISSUER 错误代码相关联。SSL 证书(SSL certificate)用于处理信用卡(Credit Card)信息或密码等敏感信息的网站。
每当您使用任何安全网站时，您的浏览器都会从该网站下载安全套接字层(Secure Sockets Layer)( SSL ) 安全证书以建立安全连接，但有时下载的证书已损坏或您的 PC 配置与SSL证书的配置不匹配。要解决此错误，有多种方法，下面列出了其中一些方法。

Fix Your Connection is not Secure Error on Firefox
Fix Your Connection is not Secure Error: Mozilla Firefox is a widely used web browser which is one of the most trusted web browsers of all time. Mozilla Firefox verifies the validity of website certificates in order to make sure that the user is accessing a secure website.
