// Depending on exactly how the new browser is being created, it might be

//
// The child creates the PBrowser as part of
// TabChild::BrowserFrameProvideWindow (which happens when the child's
// content calls window.open()), and the parent creates the PBrowser as part
// of ContentParent::CreateBrowserOrApp.
//
// When the parent constructs a PBrowser, the child trusts the app token it
// receives from the parent. In that case, context can be any of the
// IPCTabContext subtypes.
//
// When the child constructs a PBrowser, the parent doesn't trust the app
// token it receives from the child. In this case, context must have type
// PopupIPCTabContext. The browser created using a PopupIPCTabContext has
// the opener PBrowser's app-id and containing-app-id. The parent checks
// that if the opener is a browser element, the context is also for a
// browser element.
//
// This allows the parent to prevent a malicious child from escalating its
// privileges by requesting a PBrowser corresponding to a highly-privileged
// app; the child can only request privileges for an app which the child has
// access to (in the form of a TabChild).
