This is the plugin that pops up the dialog asking to download apropriate plugin. This can be really annoying while browsing the sites with a lot of flash.
To disable it rename libnullplugin.so in to some other name, Then put in to
prefs.js this line:
user_prefs("plugin.display_plugin_downloader_dialog", false);
This is a bit drastic but I could not find any other solution that would
work, short of modifying null plugin.
