推荐答案

使用Firefox 17在网络上运行时已将其删除

It was removed from running on the web with Firefox 17

https://developer.mozilla.org/en-US/docs/Bypassing_Security_Restrictions_and_Signing_Code

Firefox的早期版本允许网站分隔主体 使用签名的脚本，并请求范围内的额外权限 使用称为enablePrivelege的函数对脚本进行签名.这些功能 (除了滥用)使用得很少，而且它的复杂性 性能改进困难.签名脚本隔离原为 已在错误726125中删除，在错误中已删除了enablePrivilege提示 750859，并且enablePrivilege本身在错误757046中被削弱.

Early versions of Firefox allowed web sites to segregate principals using signed scripts, and request extra permissions for scopes within signed scripts using a function called enablePrivelege. These feature was not used much (aside from abuse), and its complexity made performance improvements difficult. Signed script segregation was removed in bug 726125, the enablePrivilege prompt was removed in bug 750859, and enablePrivilege itself was nerfed in bug 757046.

EnablePrivilege在Firefox 15中被禁用，并将在 Firefox 17.

EnablePrivilege is disabled in Firefox 15 and will be removed in Firefox 17.

需要其他权限的站点现在应询问Firefox用户 安装扩展程序，该扩展程序可以与非特权页面进行交互 如果需要的话.

Sites that require additional permissions should now ask Firefox users to install an extension, which can interact with non-privileged pages if needed.
