Use jQuery to Select Visited Links

The given approach has been disabled for security reasons.

As it is possible to retrieve a visitor's history by checking for visited links, certain measures have been taken by browser vendors to prevent this.

Checked in Chrome and FF - both don't support $("a:visited") any longer.

I found workaround based on LocalStorage on Nevyan's Blog: Mark visited links using JavaScript and localStorage

He proposed clean JavaScript code to store links clicked by page user in LocalStorage and add class "visited" to parent of an <a> element:

function check_visited_links() {
    var visited_links = JSON.parse(localStorage.getItem('visited_links')) || [];
    var links = document.getElementsByTagName('a');
    for (var i = 0; i < links.length; i++) {
        var that = links[i];
        that.onclick = function() {
            var clicked_url = this.href;
            if (visited_links.indexOf(clicked_url) == -1) {
                visited_links.push(clicked_url);
                localStorage.setItem('visited_links', JSON.stringify(visited_links));
            }
        }
        if (visited_links.indexOf(that.href) !== -1) {
            that.parentNode.className += ' visited';
        }
    }
}

I don't know if it's safer than :visited approach though.
