Mozilla the organization are providing to me a piece of software (the browser), which after me downloading it, should have absolutely nothing to do with Mozilla, their services or servers. Unless, of course, I explicitly instruct the browser to connect there, which is unlikely, because I don't want anything to do with them or with their services.
