Mozilla Firefox claims to be open source in their opening line of their Terms of Use "Firefox is free and open source web browser software, built by a community of thousands from all over the world"

In the same vein, Mozilla also changed their ToU and PS to include a statement that says "We have always prioritized user privacy and will continue to do so. We use data to make Firefox functional and sustainable, improve your experience, and keep you safe. Some optional Firefox features or services may require us to collect additional data to make them work, and when they do, your privacy remains our priority. We intend to be clear about what data we collect and how we use it."


In contradiction, Mozilla also stated, "You give Mozilla all rights necessary to operate Firefox, including processing data as we describe in the Firefox Privacy Notice, as well as acting on your behalf to help you navigate the internet. When you upload or input information through Firefox, you hereby grant us a nonexclusive, royalty-free, worldwide license to use that information to help you navigate, experience, and interact with online content as you indicate with your use of Firefox."

Mozilla is saying two things that mean the opposite.
