xulrunner, C#: how to change html? -

i moved project custom webbrowser , choose xulrunner. use xulrunner 33 , geckofx 33. so, adding in project , initialize it.

in program use custom html scenaries, how can change html? webbrowser example is: webbrowser1.documenttext = "html code here"; xulrunner have document (read only), documenttitle, domdocument (also), text (doesn't affect) , can't use change html. how possible?

the geckofx 33 have loadhtml method instead of documenttext. so, example:

geckowebbrowser.loadhtml("html code here", "url of page here");
