Question

我试图通过this示例提供命令行选项，我在浏览器控制台中收到此错误：

Bootstrapped清单不允许使用'component'指令。
Bootstrapped清单不允许使用'contract'指令。
Bootstrapped清单不允许使用'category'指令。

params：-no-remote -p Developer -jsconsole -ssprint:1137403

这是我的文件的内容：

该示例使用的chrome清单仅对（已弃用的）xul覆盖扩展类型有效。在bootstrapped扩展中，您需要提供bootstrap.js，然后使用Cu.import加载其他模块。

有关代码迁移指南，请参阅How to convert an overlay extension to restartless。

此外，您可能希望跳过另一个步骤以使用SDK extension APIs，它本质上是一种特殊形式的引导扩展，可提供更稳定的API。

Bootstrapped清单不允许使用'component'指令
