If you’re concerned about privacy you might be worried by the “Like” button found on lots of web sites. If you’re logged onto Facebook while you visit such pages Facebook knows that you were there…
So what can you do to disable that worrysome behavior? Simple. Use Firefox and the NoScript extension. Open the NoScript “Options” dialog, switch to the “Advanced” tab and then the “ABE” sub-tab, enable the ABE feature by activating the “Enable ABE” checkbox, and add the following snippet to the “USER” ruleset:
# This one allows Facebook scripts and objects to be included only # from Facebook pages Site .facebook.com .fbcdn.net Accept from .facebook.com .fbcdn.net Deny INCLUSION(SCRIPT, OBJ, SUBDOC)
Presto! You no longer need to worry about Facebook spying on you on “foreign” pages… đ
