Hey, that&#x27;s actually the wrong link for the search add-on.<p>What you&#x27;ve downloaded is a deprecated earlier prototype that may not work at all--you&#x27;re looking at the wrong github repo. (I just took down the built add-on, so other people don&#x27;t make the same mistake.)<p>Test Pilot is about reconnecting desktop Firefox with its community; it&#x27;s about more than just whatever add-ons are available today. We have feedback forms now, we&#x27;ll have Discourse user forums integrated soon, and I hope we can eventually start building ideas that come from the community, with the help of the community. You should give it a try :-)
