After stepping through the code, I have confirmed that the XPConnect stack is the issue. The relevant JSContext is not on the stack top and hence the Assert fails. So what exactly is the proper way to achieve this. i.e If I have a nsIWebBrowser object in my C++ code with me and I have a HTML page loaded, How can I call a JS Function (by name) that is present in that HTML page. _______________________________________________ dev-embedding mailing list dev-embedding@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-embedding
