Hi,
   each time I open a page which embeds a Flash object, a popup appears which says:

----------
This page contains information of a type (application/x-shockwave-flash) that can only be viewed with the
appropriate Plug-in.
Click OK to download Plugin.
----------

   I certainly don't want Flash, and I don't like that Conkeror asks me each time. There should be a way
to remember the user's decision... or a way to disable this dialog.


   You can use this code to try:


 <embed src="http://widget.meebo.com/mm.swf" type="application/x-shockwave-flash" />
Hola

  Or test it by opening any of these URLs:
- http://my.colby.edu/ics/Libraries/
- http://www.jivesoftware.com/


   This seems to happen only in a computer running Ubuntu 8.04. In my home computer running Debian
unstable, no popup appears. However, both have the same values in about:config:
- application.use_ns_plugin_finder;false
- plugin.expose_full_path;true
- plugin.override_internal_types;false
- privacy.popups.disable_from_plugins;2
- security.xpconnect.plugin.unrestricted;true

  With latest conkeror from Git, and this Xulrunner:
ii  xulrunner                 1.8.1.13+nobinonly-0ubunt XUL + XPCOM application runner


   Greetings,
Daniel
