Get information about installed add-ons.

With the management API you can:

• get information about installed add-ons

• enable/disable add-ons

• uninstall add-ons

• find out which permission warnings are given for particular add-ons or manifests

• get notifications of add-ons being installed, uninstalled, enabled, or disabled.

Most of these operations require the "management" API permission. Operations that don't provide access to other add-ons don't require this permission.
