- * NewTabWebChannel is the conduit for all communication with unprivileged newtab instances.
- *
- * It allows for the ability to broadcast to all newtab browsers.
- * If the browser.newtab.remote pref is false, the object will be in an uninitialized state.
- *
- * Mode choices:
- * 'production': pages from our production CDN
- * 'staging': pages from our staging CDN
- * 'test': intended for tests
- * 'test2': intended for tests
- * 'dev': intended for development
- *
- *  An unknown mode will result in 'production' mode, which is the default
- *
- *  Incoming messages are expected to be JSON-serialized and in the format:
- *
- *  {
- *    type: "REQUEST_SCREENSHOT",
- *    data: {

- *  Or:

- *
- *  Outgoing messages are expected to be objects serializable by structured cloning, in a similar format:

-/*
- * A service that allows for the overriding, at runtime, of the newtab page's url.
- * Additionally, the service manages pref state between a remote and local newtab page.
- *
- * There is tight coupling with browser/about/AboutRedirector.cpp.
- *
- * 1. Browser chrome access:
- *
- * When the user issues a command to open a new tab page, usually clicking a button
- * in the browser chrome or using shortcut keys, the browser chrome code invokes the
- * service to obtain the newtab URL. It then loads that URL in a new tab.
- *
- * When not overridden, the default URL emitted by the service is "about:newtab".
- * When overridden, it returns the overriden URL.
- *
- * 2. Redirector Access:
- *
- * When the URL loaded is about:newtab, the default behavior, or when entered in the
- * URL bar, the redirector is hit. The service is then called to return either of
- * two URLs, a chrome or remote one, based on the browser.newtabpage.remote pref.
- *
- * NOTE: "about:newtab" will always result in a default newtab page, and never an overridden URL.
- *
- * Access patterns:
- *
- * The behavior is different when accessing the service via browser chrome or via redirector
- * largely to maintain compatibility with expectations of add-on developers.
- *
- * Loading a chrome resource, or an about: URL in the redirector with either the
- * LOAD_NORMAL or LOAD_REPLACE flags yield unexpected behaviors, so a roundtrip
- * to the redirector from browser chrome is avoided.
