Finding Previous Url From Window.history

I've hosts file blocking so time to time, I get these 'Page not found' errors browsing thru deals. Since I got tired of copying the target url, unescaping, replacing it in address

Solution 1:

Found a way (at least while it lasts!)

Chrome sets the entire URL in document.title, so querying it is all that's needed. Here's the modified code if anyone's interested:

(function () {
    var href = document.title;
    var loc = href.lastIndexOf('http');
    if (loc > 0) {
        var endLoc = href.indexOf(' is not available', loc);
        endLoc = endLoc > 0 ? endLoc : href.length;
        window.location.href = unescape(unescape(href.substring(loc, endLoc)))
    }
})()

Note: The double unescape is needed for links coming via Google Ads.
