How to implement copy to clip board functionality in GWT for FireFox browser

I could able to achieve copy to clipboard on button click in IE with following code snippet.

PFB the JSNI method:

private static native void copyTextToClipBoard(UIObject panel) /*-{
    var frame = $doc.getElementById('__printingFrame');
    if (!frame) {
        $wnd.alert("Error");
        return;
    }
    frame = frame.contentWindow;
    var doc = frame.document;
    doc.open();
    doc.write(panel);
    if (doc.body != null) {
        var r = doc.body.createTextRange();
        r.execCommand('copy');
    } else {
        return alert("Only Internet Explorer will support this action");
    }
}-*/;

But as we know this code will never work for FireFox. Is there any way that we could achieve this behavior in FireFox.

Well,

if ("your clients simply cannot have flash installed" && 
        "you must have them copying and pasting all around") {
    if (they("configure firefox to enable javascript access to the clipboard")
            .seeBelow()) {
        you("can implement a solution in javascript, and wrap it with JSNI");
    } else {
        they("must install a firefox addon for that purpose, there are plenty"); 
    }
} else {
    just("go with flash, man");
}

See how to enable clipboard access for javascript (by editing user.js).

Take a look at ZeroClipboard. You can probably use JSNI to inject a piece of code as in the examples in the link.
