本頁在描述 Firefox Nightly 與 Firefox Developer Edition 第 52 版以後的 JavaScript 除錯器(Debugger)。

要找在此版本之前、或是位於 Beta 與 Release 通道的 Firefox,請參閱Firefox 52 之前的除錯器

如果你是這個版本的除錯器,但需要用舊版本的除錯器,你可以去 about:config 那裡,把「devtools.debugger.new-debugger-frontend」選為 false

JavaScript 除錯器可以讓 JavaScript 單步執行,並檢查或修改其狀態,以便查找錯誤。

你可以在本地或是在遠端除錯用 Firefox 除錯。一個遠端除錯的例子,就是在 Android 設備上執行 Firefox for Android。請參閱遠端除錯以理解如何把欲除錯的目標,連接到除錯器上。

The debugger ships inside Firefox, and these pages describe how to use the version that's embedded in Firefox. However, you can also run it as a standalone web application, and can then use it to debug code running in other browsers and in Node. For more details on that, see the project's GitHub repository.
