I agree. They can send my data wherever they want - as long as they tell me about it so that I can make an informed decision.
Now, nightly is nightly - you don't accidentally build and install it on your system.
But if this behavior is included in other pre-release versions (such as the developer edition), the need for informing the user becomes even more important. I've installed the developer edition from the Arch linux User Repository (AUR), which means that I don't see any release notes or information boxes on the developer edition website when I'm getting the software.
A small popup in a corner telling me that "There's a new way to help improve firefox" after an upgrade/install would solve this. I don't want 15 levels of confirmation and a roll of tin foil - I just want something informing me that my data will be sent to a new receiver, and why.
