For anyone else banging their head on this particular wall:
https://bugzilla.mozilla.org/show_bug.cgi?id=533245#c13 In short the solution is to implement GetVisibility like this: NS_IMETHODIMP WebBrowserChrome::GetVisibility(PRBool * aVisibility) { NS_ENSURE_ARG_POINTER(aVisibility); *aVisibility = PR_TRUE; return NS_OK; } rather than like this: NS_IMETHODIMP WebBrowserChrome::GetVisibility(PRBool * aVisibility) { if(! m_pBrowserFrameGlue) return NS_ERROR_FAILURE; m_pBrowserFrameGlue->GetBrowserFrameVisibility(aVisibility); return NS_OK; } _______________________________________________ dev-embedding mailing list dev-embedding@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-embedding
