Why in an AllowAny view of Django I get 401 Unauthorized using Firefox but not using Edge or Postman?

Question

I'm using knox LoginView to make the login of my backend. This is the code of the view:

class Login(LoginView):
    permission_classes = (AllowAny,)

    def post(self, request, format=None):
        serializer = AuthTokenSerializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        user = serializer.validated_data['user']
        login(request, user)
        return super(Login, self).post(request, format=None)

When I execute my frontend (developed with angular) and try to login using Microsoft Edge everything works fine. I get the token and save it in local. Same result if I execute a POST using Postman. But, If I try to do the same using Firefox I receive 401 Unauthorized with this JSON:

{"detail":"Invalid token."}

Why does it ask for a token if its an AllowAny view? Why does it work in Edge and Postman but not in Firefox?

More data:

This is the authentication class in settings.py:

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'knox.auth.TokenAuthentication',
    ),
}

EDIT: Actually, it works usign Firefox Developer Edition.
