I'm developing a business websites, on which certain Javascripts and HTML work with Firefox only. How can I force user to not use other browser, something like when they open the site on Chrome, IE or Opera, they will receive a message and will be redirected to an info page.
FYI, the language I used is ASP.NET Web Form.
Edited: The solution has more than 200 pages, so I think I'll put it in a Masterpage
Edit 2: Javascript or Server script is ok
Edit 3: Reason: I'm using a third-party HTML control library. That library's DataGrid is used intensively. On the DataGrid, I always have some hidden columns and this works well with Firefox. But on Chrome, the hidden columns are exposed. Since there is no fix and I'm not ready to upgrade the library, I would like to ban other browsers as an immediate measure
Thank you
