It says that when this is enabled, "Mozilla receives your search queries".

This is a real shame as I was hoping it would be more privacy focused. Maybe it could just download a list of advertisers locally and then locally compare the search text to the ads but instead everything typed in to the address bar will get sent to someone else's servers. I might have had it on if it was all done locally (but I guess there is too many flaws in doing it locally for Mozilla).

Still very sad they are doing this, but at least it seems an easy opt-out/not opt-in.
