Are you trying to block because the site does not work well using Mozilla- but works great for IE? I do not think GP has any out of the box configurable options for mozilla but this site has a FF adm but I am not sure if it will do what you require http://sourceforge.net/project/showfiles.php?group_id=129699 If my initial question is correct- you may need to do some work on the webserver(if you manage it) to read the get request and put up an error page if the request comes from firefox but let it through if it is an IE Browser. Am I wrong in assuming Mozzila and firefox are the same?
