Could you describe this in a little more detail? If you are seeing a bar below the address bar saying that the site wants to refresh, you can allow all refreshes here: orange Firefox button ''or'' classic Tools menu > Options > Advanced On the "General" mini-tab, uncheck the box for "Warn me when websites try to redirect or reload the page" I don't know whether there is a site-by-site way to create an exception to that setting; I haven't noticed one.
