From the new terms:
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.
Does having a ToS mean that Firefox is no longer FOSS? Freedom 0 of FOSS is: “The freedom to run the program as you wish, for any purpose”. Isn’t that violated if you can only use the software under the condition of accepting terms of service?
