Determine the browser using Javascript/JQuery

You can use the navigator.userAgent to find which browser user is using

function BrowserDetection() {
                
                //Check if browser is IE or not
                if (navigator.userAgent.search("MSIE") >= 0) {
                    alert("Browser is InternetExplorer");
                }
                //Check if browser is Chrome or not
                else if (navigator.userAgent.search("Chrome") >= 0) {
                    alert("Browser is Chrome");
                }
                //Check if browser is Firefox or not
                else if (navigator.userAgent.search("Firefox") >= 0) {
                    alert("Browser is FireFox");
                }
                //Check if browser is Safari or not
                else if (navigator.userAgent.search("Safari") >= 0 && navigator.userAgent.search("Chrome") < 0) {
                    alert("Browser is Safari");
                }
                //Check if browser is Opera or not
                else if (navigator.userAgent.search("Opera") >= 0) {
                    alert("Browser is Opera");
                }
            }
