The Mozilla default plugin controls the Firefox plug-in finder, the tool activated when you load a page that requires a plug-in, such as Flash, that you have yet to install. It's disabled by default, so you'll receive the informational bar alerting you need the plug-in. If you enable it, you'll receive a popup box whenever a plug-in is required, giving you additional information about it, such as the download site. I just leave it alone, but if you'd like to enable it:
1.) Go to about:config
2.) Find: plugin.default_plugin_disabled
3.) Double-click the entry to change the value.
4.) ''True'' disables it while ''false'' enables it.
Hope this helps,
Mozilla default plugin.

It is not enabled. Do I need to enable it? If yes, How?
