I want users not to download anything from firefox. How can this be done??
Look at Public Fox: https://addons.mozilla.org/firefox/addon/3911
Be aware that it is an extension and that extensions can easily bypassed by starting Firefox in Troubleshoot Firefox issues using Safe Mode.
Thank you cor-el. I have installed it and its working... great...
