This is a new tracker related to additional WebExtensions devtools APIs that we are investigating, planning and/or implementing as follow ups of the initial devtools APIs subset that has been provided on Firefox 54 and Firefox 55 by Bug 1211859 (the previous tracker) and its dependencies.

Of all the dependencies, here's how I would prioritize: bug 1366752: ExtensionPanel.onSearch event is unimplemented bug 1361121: Implement devtools.inspectedWindow.getResources bug 1311171: Implement the devtools.network.onRequestFinished API event (ember?) bug 1341304: Implement devtools.panels.elements.onSelectionChanged bug 1341305: Implement devtools.panels.elements.createSidebarPane bug 1333400: Get devtools.network.onNavigated working in the case of frame switching bug 1347108: Panels added to DevTools with WebExtensions take a considerable amount of time to show up bug 1366755: DevTools panel icon is inverted with Light Theme (not sure what this is) bug 1293298: Implement events in SubTypes defined in the WebExtensions API schema files (useful but haven't seen much of it other than lighthouse) bug 1311177: Implement the devtools.network.getHAR API method That's purely from my perspective when reviewing the WebExtensions I've been seeing so far, take with a grain of salt.
