As a warning, the very popular browser Firefox, has just released its latest update, Firefox 10. They are calling it a security update but it will break your compatibility with Oracle BI 11g (220.127.116.11).
If you don’t install the update you won’t bump into this issue.
If your FF browser is set up to automatically update then you will have to uninstall and re-install the previous version if you want to view Oracle BI 11g presentation services using FF.
So, if I were you I would turn the automatic updates OFF. You can do this through Firefox > Preferences > Advanced on a Mac. Or, Tools > Options > Advanced on Windows.
Although the Firefox update messes up Oracle BI 11g viewing it does offer some really new features which are great for developers.
