BROWSER PLUG IN

I am looking for a browser plug in with an auto install pop up prompt, that people will be prompted to install on their computer when they come to my site or view my ad. Once installed, this application will make their browser go to a specific page (one I designate) anytime they hit a 404 error page, or any browser error page in their browser.... The application needs to pass on the URL they were trying to reach, and possibly break it down into possible key words that can be used to provide alternative links on our page via google or other search technlogy. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
