How to restrict portal to IE only, display error message to user if Firefox
One way to acheive this is to customize your login page and add a script to detect the browser and act accordingly.
For customizing the Loginpage, you can find weblogs or pdfs on sdn or refer the thread :

Once you have the logonpage.jsp file, Add the following lines to it in the script block where you find the js functions clearEntries() and setFocusToFirstField().
if(navigator.appName != 'Microsoft Internet Explorer')
{
window.location='http://www.google.co.in';
}
In place of the Google url, give the url of the page to which you want to redirect. Add these lines as the first lines in that script block.
Then build the par file and upload it to the server. Follow the instructions to change the login page in the authschemes.xml file.
