Answer 1

finally i got the answer after creating element we need to append the element to the document body.here is the code. https://support.mozilla.org/en-US/questions/968992

var redirect = <HTMLAnchorElement>document.createElement("a"); 
document.body.appendChild(redirect); //required in FF, optional for Chrome
redirect.href = 'https://www.google.co.in/';
redirect.target = '_blank'; 
redirect.click();
