Hi, I need a software written that is sort of a surfing track & control application. it is meant to be implemented at my workers' pc's in my company in order to prevent them from going to non-legitimate sites and to track their daily progress at work. The software is to be implemented as a toolbar on the user's browser (either FF or IE6,7,8). It will have some extra added values to the worker (will be explained later on) Needs to be delivered as firefox addon file and IE addon file (compatible with versions 6,7,8) Please contact me only if you have prior experience in toolbar programming, security solutions programming or similar. Thanks ## Deliverables Specifications and exact PRD will be delivered to the chosen seller.
