|Feature overview=We currently do not provide adequate warning to users that new third-party provided add-ons have been installed. This project will ensure that users opt-in to all add-ons that aren't installed through the Firefox UI.
This feature falls primarily in the '''Experience''' category (from the "Discover, Experience, and Connect" vision statement.)
|Feature users and use cases=* Make users aware when new add-ons have been installed that they may not know about
** Users should be able to opt out of such add-ons before the add-on's code has a chance to run
