Hello, I need to restrict the use of Firefox and Internet Explorer to only specified websites that we use for business use. I have a problem with a number of employees using unauthorized and dangerous websites that have put my business computers at risk. Since it is impossible to police the employees viewing habits in real time, I need to restrict the viewing. How do I set up a list of only allowed sites that can only be overridden by admin privileges despite user accounts?

Chosen solution

You will have to block such unwanted sites in a firewall or router or proxy and only allow access via that proxy.
All other ways can easily circumvented, by starting Firefox in Safe mode if it is an extension or by using a portable Firefox version.
