I've been digging around and I can't seem to find a "yes there is and here you go" answer for this. I love NoScript for FF and I've been using ScriptSafe for Chrome. The problem is the most vulnerable browser (*cough* IE *cough*) seems to lack this. That issue aside, I was also thinking of how I could implement this in an enterprise environment. It would be great if I could deploy this to IE, as we still have to use it for "compatibility" with most of our sites, and then I maintain a central TRUST list and finally feel safe that my users won't get fooled into clicking on a link or ad they shouldn't have.
Anybody have any ideas on a solution or how you handle it in your environment?
