Stop Twitter from tracking the webpages you go to.
Twitter is notified whenever you visit one of the more than 20 percent of sites on the web that include Twitter widgets (see http://j.mp/dcdefcon).
Turn off the flow of your data to them!
Twitter Disconnect blocks all traffic from third-party sites to Twitter servers but still lets you access Twitter itself.
Note: Read the FAQ at http://j.mp/fbdcinstall to learn about the warning you get when installing Twitter Disconnect.
