Firefox has a notoriously sticky cache. I too had members complaining that topics did not refresh on new posts. I think I fixed the problem with mod_expires in htaccess -  something like:

# HTML
ExpiresByType text/html "modification plus 60 seconds"

Then you do the same for your images/video/css/js in times appropriate for your server and board. Since doing the above none of my members have reported the stale Firefox cache issue.

Before I had access plus*** and that did not work at all.
