- Create a new XPCOM component UserCharacteristicsPageService backed by a JS implementation. It will be accessed as a Service, so there is only ever one of them - Inside UserCharacteristicsPageService use a HiddenFrame to open a page invisible to the user. (In this patch it's a random https:// site, in the next patch it will become an about: page) - Create a Parent/Child JSWindowActor so that the hidden webpage (which will eventually be in the privilegedabout content process) can communicate back to the parent. - Use Topics/Observers so the Actor can be registered when we need it and then unregistered when we're done. The registering occurs in a RFPHelper which a separate thing already running and listening for stuff. - Inside nsUserCharacteristics.cpp::CanvasStuff() we ask our service to load the webpage, then will await a promise indicating the page has been loaded. That promise is the return value of UserCharacteristicsPageService::createContentPage() and is resolved after UserCharacteristicsPageService::pageLoaded calls backgroundResolve(). That, in turn, happens after UserCharacteristicsParent gets the message from UserCharacteristicsChild that the DOMContentLoaded event has occurred. The HiddenFrame stuff is influenced by PageDataService.sys.mjs - that's where the HiddenBrowserManager stuff came from. In the next patch we'll actually do something when that promise is resolved.
