+Extensions can use the
+[Dev Tools API](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/devtools)
+to extend the browser's developer tools. When doing so, these extensions can run

+- These contexts have `tabId` and `frameId` as -1 as these contexts are not
+hosted inside a tab.
+- If developer tools are docked to a tab, the `windowId` will be the ID of the
+window containing the tab.
+- If developer tools are undocked, the `windowId` will the ID of the developer
+tools window.

-a panel (an extension view) within the developer tools console. These views
