Compatibility with ifarme jump browsers

Question about compatibility with ifarme jump browsers? I have three pages in total: index, top, and main. I want to use iframe to refresh main. However, in firefox, click the link to refresh the new window, but ie won't. how can I set it, so that firefox does not pop up ??? The younger brother's level is too limited. could you please help me? because the posting permission is only compatible with ifarme jump browsers?
