Here are the steps I used:
以下是我使用的步骤：
- Installed Linux mint 16 on VBox:
> uname -a Linux me-VirtualBox 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:12:00 UTC 2013 i686 i686 i686 GNU/Linux - Cleaned all Java instances.
- Followed instructions to installjdk-7u51-linux-i586.tar.gz on Linux.
- Verified installation
> java -version java version "1.7.0_51" Java(TM) SE Runtime Environment (build 1.7.0_51-b13) Java HotSpot(TM) Client VM (build 24.51-b03, mixed mode) - Verified plugin:
> pwd /home/me/.mozilla/plugins > ls -l total 0 lrwxrwxrwx 1 me me 46 Jan 22 02:42 libnpjp2.so -> /usr/lib/jvm/jdk1.7.0/jre/lib/i386/libnpjp2.so - Verified Java plugin:
- Verified Firefox activation:
- Started the Java ControlPanel; set security to Medium:
- Clicked Apply.
- Restarted Firefox.
- 在 VBox 上安装 Linux mint 16：
> uname -a Linux me-VirtualBox 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:12:00 UTC 2013 i686 i686 i686 GNU/Linux - 清理了所有Java 实例。
- 其次说明安装在Linux上的jdk-7u51-Linux的i586.tar.gz。
- 验证安装

I had this issue. The security settings in the ControlPanel seem to be user specific. Try running it as the user you are actually running your browser as (you are not browsing as root!??) and setting the security level to Medium there. - For me, that did it.
我有这个问题。ControlPanel 中的安全设置似乎是特定于用户的。尝试以您实际运行浏览器的用户身份运行它（您不是以 root 身份浏览！??）并将安全级别设置为中。- 对我来说，做到了。

As an alternative answer, there's a command line to invoke directly the Control Panel, which is javaws -viewer, should work for both openJDK and Oracle's JDK (thanks @Nasser for checking the availability in Oracle's JDK)
作为替代答案，有一个命令行可以直接调用控制面板，即javaws -viewer，应该适用于 openJDK 和 Oracle 的 JDK（感谢 @Nasser 检查 Oracle JDK 中的可用性）
Same caution to run as the user you need to access permissions with applies.
与您需要访问权限的用户一样谨慎运行。
回答by Ridzuan Adris
The application that you are running is blocked because the application does not comply with security guidelines implemented in Java 7 Update 51
您正在运行的应用程序被阻止，因为该应用程序不符合 Java 7 Update 51 中实施的安全准则

You can also use Edit Site Listand make it be an exception so that you can run it from the specific website.
您还可以使用“编辑站点列表”并将其设置为例外，以便您可以从特定网站运行它。

Just start your browser with superuser rights, and don't forget to set Java's JRE security to medium.
只需以超级用户权限启动浏览器，不要忘记将 Java 的 JRE 安全性设置为中等。
