My experience to write a plugin for Firefox is below zero. Is someone out there who could point me to sample code on how to get this accomplished in C++ with VS2005/8?
What I need to do with JavaScript in the hosting html page is something like this:
var obj = document.getElementById("MyFFPlugin");
var value = obj.CalculateValue;
// Work with calculated value
The SDK has basic samples on how to write mozzila plugins which can be downloaded here: http://mxr.mozilla.org/seamonkey/source/modules/plugin/tools/sdk/
Here is the official mozilla plugin site http://www.mozilla.org/projects/plugins/
Hope it helps.
