Whenever I got to Google Maps lately, I end up on some form of “https://www.google.com/maps/preview,” which generates a non-functional crappy map. I can revert to the regular map by clearing recent history (cache/cookies/etc.), but the useless preview comes back the second time I go to maps.googl. As far as I know I didn’t respond to Google’s nagging and try out their new interface; it just keeps defaulting to it. None of my other machines are having this problem (the problem machine is FF 27.0.1; NoScript and Ghostery are not blocking anything).
