Menu
I used this JavaScript code to full screen the page:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<div style="border:1px solid red;height:100px;width:100px;background-color:red;" onclick="requestFullScreen(document.body)"></div>
<div style="border:1px solid red;height:100px;width:100px;background-color:blue;" onclick="exitFullScreen(document.body)"></div>
<script>
function requestFullScreen(element) {
// Supports most browsers and their versions.
var requestMethod = element.requestFullScreen || element.webkitRequestFullScreen || element.mozRequestFullScreen || element.msRequestFullscreen;
if (requestMethod) { // Native full screen.
requestMethod.call(element);
} else if (typeof window.ActiveXObject !== "undefined") { // Older IE.
var wscript = new ActiveXObject("WScript.Shell");
if (wscript !== null) {
wscript.SendKeys("{F11}");
}
}
}
</script>
<script>
function exitFullScreen() {
if (document.exitFullscreen) {
document.exitFullscreen();
}
else if (document.msExitFullscreen) {
document.msExitFullscreen();
}
else if (document.mozCancelFullScreen) {
document.mozCancelFullScreen();
}
else if (document.webkitCancelFullScreen) {
document.webkitCancelFullScreen();
}
}
</script>
</body>
</html>
but it show "press esc to exit full screen" in full screen mode. How to remove "press esc to exit full screen" in firefox and chrome?

It's super easy in Firefox:
about:configbrowser.fullscreen.exit_on_escapetrue to change it to false
