It's the closest we have to a browser not controlled by the corporate giants. Sometimes Mozilla makes unpopular choices and people raise a stink about it, but we do that because we hold them to a higher standard. With Microsoft and Google, we just expect them to Do More Evil, with Mozilla we expect Good and will complain loudly when they fail to uphold our principles, and we recommend Firefox because we feel like it is possible to expect Good from them.
