Seeing my Facebook details plastered over other websites always concerns me, and I definitely do not want to login using my Facebook details!

Adblock Plus to the rescue! Found the filter rules here (along with general instructions for FF and Chrome!).

Simply download Adblock for Chrome and add the following to the filter:

\*.facebook.\*\$domain=\~facebook.com|\~127.0.0.1

Simple as that, Facebook Connect disappears from every site!
