Some Mozilla developer was kind enough to write a widget which can be easily embedded into a gtk application. Anyway, the widget has several problems which are quite important if you want to add it to a docking widget:

• It does strange things if not realized
• It stops working if it is reparented

To get around this I have created a wrapper widget around it which automaticly creates a gtkmozembed widget on "realize" with g_idle_add(create_widget) and destroys the gtkmozembed widget on "unrealize". Et voilà, we have a working Devhelp plugin in Anjuta.
