The New York Times and Washington Post both use a "fingerprint" method to identify unique users using things like your browser version and IP address. I like using Firefox nightly because a quick update to Nightly will make it appear that I'm a new user and will reset my free "monthly" article limit. That's also why switching browsers will work for some people, but not others.
Open browser incognito, open google, paste link, profit. Works for me.
