You can use AutoJSContext to run javascript with geckofx.

Something like:

GeckoWebBrowser browser = ....;

using (AutoJSContext context = new AutoJSContext(browser.JSContext))
{                               
   string result;
   context.EvaluateScript("3 + 2;", out result)
}

See EvaluateScript unittests for more info and examples.

If you are using a super old version of geckofx you may need to get a later version - geckofx
