Thanks for the reply. I'm fairly sure that force download was available but not 100% so. I think the problem I'm facing now is more of a site-wide issue related to 2.4 with Firefox and Chrome. The site seems to work just fine with Internet Explorer.
Anyway, one problem is that with Firefox and Chrome, URL resources open up another Moodle page where you need to click on the link to an external URL. However, with Internet Explorer the URL resources open the external pages immediately.
I haven't seen anyone else complain about 2.4 not working properly with Firefox and Chrome so I don't know what it is.
