自舉清單不得用<a href="https://developer.mozilla.org/en-US/docs/Mozilla/Tech/XUL/Providing_Command-Line_Options" rel="nofollow">this</a>例如使用「組件」指令

Question

我想prroviding命令行選項， 我在瀏覽器控制檯收到此錯誤：

• 自舉清單不允許使用「組件」指令。
• 自引證明不允許使用'合同'指令。
• 引導式清單不允許使用'category'指令。

該示例使用僅適用於（不推薦）xul覆蓋擴展類型的chrome清單。在自舉擴展中，您需要提供bootstrap.js，然後使用Cu.import加載其他模塊。

有關代碼遷移指南，請參閱How to convert an overlay extension to restartless。

此外，您可能需要跳過另一個步驟來使用SDK extension APIs，這本質上是一種特殊形式的自舉擴展，它提供了更穩定的API。
