Facebook "Like" buttons on the web will still track your activity and link it to your profile, but you can take measures to ameliorate that (clear cookies, block the "Like" button origin URLs, and---for the most paranoid among us---use Tor so that not even the IP addresses are easily correlated to your activity).
