I don't think they use a separate EULA for the binaries. I've found this:

> Mozilla software is made available to you under the terms of the Mozilla Public License 2, a free software license, which gives you the right to run the program for any purpose, to study how it works, to give copies to your friends and to modify it to meet your needs better. There is no separate End User License Agreement (EULA).

Correction: they do have separate ToS for the official binaries (https://www.mozilla.org/en-US/about/legal/terms/firefox/). Still, the "acceptable use" clauses only apply to Firefox services.
