Using xss-protection and blocking/bypassing javascript code

Modern browsers have increased a function called "xss protection", which helps to avoid "Cross Site Scriptings" by preventing any script in the url from executing (complete tags as "<script>alert('xss')</script>" are totally stopped). Thanks to this protection, an attacker can spoof a fake XSS attack and stop code blocks in the webpage, avoiding possible security checks(example below).

Examples working only with Chrome and Safari browsers.

Tested browsers: Chrome ( Desktop and Mobile ), Safari, Opera, Firefox.
