OBIEE: Replacing Internet Explorer (IE) with Mozilla Firefox when SSO enabled

Sometimes companies configure OBIEE to be compatible only with Internet Explorer (IE) for security purposes, especially when Single Sign-On is enabled, which in most cases works with IE only. 

If you like to use Mozilla Firefox instead, do the following:

1. Type "about:config" into an address bar, which will show all setting rules
2. Right click anywhere

    a. Select: New > String, then OK

3. Enter: general.useragent.override > OK
4. Enter: Mozilla/5.0 (Windows; Windows NT 6.1; rv:10.0) Gecko/20100101 Firefox/9.0 as values > OK
5. Refresh OBIEE login screen and Enjoy! :)

Hope this helped!
