Question

Is it possible to create a link with PHP , which can be opened only by Firefox and not by any other Browser?

<a href="http://www.google.com">Only with Firefox</a>;

Because there are some Websites which works better with Firefox.

If it is possible, what i must add to the link?

THX in advance

As @Steve Fenton says, I do not recommend doing such things, because the web is (or should be) open. Otherwise is you still want to do it, you need to check the browser user agent of your visitor and show (or do not show) the download button.

You can acces the browser user agent easily with jQuery:

if ($.browser.mozilla) {
  //Do the stuff
}

Or with PHP using the $_SERVER['HTTP_USER_AGENT'] variable.

But remember, the user can change the user agent of his/her browser.
