This page describes the WebExtensions devtools APIs as they exist in Firefox 54. Although the APIs are based on the Chrome devtools APIs, there are still many features that are not yet implemented in Firefox, and therefore are not documented here. To see which features are currently missing please see Limitations of the devtools APIs.

The devtools.network API lets a devtools extension get information about network requests associated with the window that the devtools are attached to (the inspected window).

Like all the devtools APIs, this API is only available to code running in the document defined in the devtools_page manifest.json key, or in other devtools documents created by the extension (such as the panel's own document). See Extending the developer tools for more.

Events

devtools.network.onNavigated
Fired when the user navigates the inspected window to a new page.
