Delete cookies and refresh
To make a bookmarklet for “deleting” cookies of the current website and refresh it with one click you can paste this code in the URL property of a bookmark.
javascript: (function() {
var cookies = document.cookie.split("; ");
for (var c = 0; c < cookies.length; c++) {
var d = window.location.hostname.split(".");
while (d.length > 0) {
var cookieBase = encodeURIComponent(cookies[c].split(";")[0].split("=")[0]) + "=; expires=Thu, 01-Jan-1970 00:00:01 GMT; domain=" + d.join(".") + " ;path=";
var p = location.pathname.split("/");
document.cookie = cookieBase + "/";
while (p.length > 0) {
document.cookie = cookieBase + p.join("/");
p.pop();
}
d.shift();
}
}
location.reload(true);
})();
