Mozilla Plug-ins for Linux

Use Help > About Plug-ins
to open about:plugins

Click on http://plugindoc.mozdev.org/
or go to Linux directly.

Where is your plugin directory? First, start Mozilla. Then, in a
terminal, enter:

$ ps aux | grep moz
$ cd </path/to/mozilla-bin>
$ ls plugins

Important: if you don't see
a plugins directory, you have two choices:

1. Install the plugins in ~/.mozilla/plugins


2. Root creates a new plugins directory in the same directory as
   mozilla-bin, and installs plugins there.
