desktop application to open URL with different browsers

Greetings, This application will help us test our website I need a desktop application that when the user right click (or holding some predetermined button) on a text box (specifically a browser URL textbox), will give me the option to open the same URL in differnt browsers (FireFox, IE, Chrome, etc), or in all of them at the same time. It should also have the option to open the same URL in different tabs of the same browser, but replacing the main web address with a predetermine IP addresses. Example, opening http://[[login to view URL]][1]? in different tabs as <[login to view URL]>, and <[login to view URL]>? The replacement to [[login to view URL]][2] (i.e. in the exmpale [login to view URL] and [login to view URL]) should be in settings, and not limited to 2 url replacements, but to as many as I need. ## Deliverables should work with xp and win 7 writeen in C#
