Our company standard is IE8 but the dojo framework build application (we built) works only in IE9 and all versions of Firefox, Safari and Chrome. Using javascript I can detect user's browser and version and force them to use FF for example. They cannot use IE9 as very few people have Windows 7. Our Sys-Admins worry that people can download "virus" by using other browsers!!!????? They need to know if we can find a version of firefox for our users to install where address bar, tool bar and all menu's are hidden but our application runs (as it is firefox). I can code that from a controlling application but a customized version of FF which can be used only for one web site is possible? Sounds stupid...i understand... any ideas in this situation? proxy server settings?
