@leachimus Fennec is essentially just Firefox with proprietary libraries removed and telemetry disabled. IronFox also removes proprietary libraries and disables telemetry, but the overall goal is to provide a hardened, privacy and security-oriented web browser, going above and beyond what standard Firefox/Fennec provide.

To be clear, Fennec is an excellent project, and I myself have personally contributed to it on multiple occasions, but it's a different project with a different set of goals than IronFox, it's difficult to compare the two.
