Method setCurrentHistoryIndex of History interface must throw Unimplemented exception. Since merging Webclient and Mozilla M16 this method doesn't work. And now this method must be implemented by another way or throw Unimplemented exception. Reproduced with Mozilla M16 and Webclient sources from July,31.
Changed summary. Old title: setCurrentHistoryIndex must throw Unimplented exceptiontCurrentHistoryIndex must throw Unimplented exception. As far as I can tell, embedding apps can't setCurrentHistoryIndex, since the only method that provides such functionality is in nsIBrowserInstance, which doesn't appear to get created in the embedded context.
session history is going to be redone. cc'ing potts
