Add firefox_xpi_bootstrapped_addon exploit
This is similar to java_signed_applet as it does not exploit a vulnerability, but hope that the user will trust the addon.unstable

|

This exploit dynamically creates a .xpi addon file.
|
||||
The resulting bootstrapped Firefox addon is presented to
|
||||
the victim via a web page with. 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.
