Thanks to Adam Lock and Rick Potts(for super reviewing Adam's patches 
quickly) we've got the following embedding interfaces/APIs frozen:

NS_InitEmbedding
NS_TermEmbedding
nsIWebBrowser
nsIContextMenuListener
nsITooltipListener
nsITooltipTextProvider
nsIEmbeddingSiteWindow
nsIWebBrowserSetup

Thanks
