As a Reddit user I'm using this simple replace function to switch to the old.reddit.com version of a page:

javascript:(function(){ if (location.hostname === "www.reddit.com") { location.href = location.href.replace("www.reddit.com", "old.reddit.com"); }})();

Necessary due to Google search results on Reddit leading to the new.reddit.com version of a page which demands a login more often than not.
