The comments said that the reason the page doesn't work on firefox is they detect the user agent for firefox and don't load the css if its found.

  Could this finally be the end of every user-agent string starting with Mozilla/?

    No, because the parent comment here is incorrect. They stated that they are using feature detection, and specifically mention user-agent as something they don't use.

      The above comment was a joke about user agent strings.
