  • The devtoolsPanel.html page is loaded only once the tab is selected

activeTab

  • Clicking the browser action icon gives the extension temporary access to the current tab: (See https://github.com/w3c/webextensions/issues/55)
    • In Chrome, this access is preserved on the top frame’s origin until the user changes origin
    • In Firefox, this access is lost after the first navigation/refresh
