Fork itself alone is enough since it implies they are not part of the original team. When they put "independent fork" which changes the meaning/intents, I would believe that they means they are forking Firefox and the original code will not the same or something. This is my assumption/observation that the owner or the members of this forked project is majority ESL. I would understand why they said independent fork because it made sense to them, however it implies different than "fork" alone.
