ASP.NET has nothing to do with Chrome extensions, by one simple reason: it's based on HTTP standards which has no notion of such extensions. Your request for browser capabilities is based on the standardized HTTP headers (but Chrome or any other browser's identity can easily mocked by any other browser; such trick is sometimes used to overcome limitation of some stupid Web sites).

I think you are trying to move in wrong direction. Decent Web application should run on all of major browser's and be focused not on "extensions", but just the opposite: on standards.

thank you for the reply. i have a code which open new tab in IE and FF, but new windows in Chrome. i did some research, they said this is the settings of the chrome itself, there's nothing we can do about it. that's why i need to use extension to help me. i tried too many ways and i give up :(

i cannot run "Proceed.Start" after i upload to server, i believe it's some security reasons

Okay, certainly a wrong move. Tab vs. separate browser window is something which is not regulated by the Web standards. It's not so good to use any of them. The user knows better how to navigate from an anchor. And even if you use some extension, why would your Web application be aware of it (which is anyway impossible)? You can use light-weight windows on the same page...

By the way, I noticed that Mozilla creates either a separate window or a tab, depending on window.open parameters. This is all browser's peculiarities (based on some common sense, hopefully) which you cannot and should not rely on. Even if some extension modify such behavior, what are you going to do with it?
