# Hint: If you use Mozilla 1.7.x gtkmozembd, you should remove
# libnullplugin.so if you want to get rid of "Default Plugin"
# window. The gtkmozembed from Firefox 1.0 has an improved nullplugin.
# Hint: You can switch between Mozilla and Firefox implementation by
# setting the library path appropiately. The Firefox version of
# GtkMozEmbed is better integrated in Gtk and has nicer scroll-bars
# and message boxes. (use LD_LIBRARY_PATH, see extconf.rb or do some
# googling)
# Happy coding, Mirko Maischberger
