What is worse? Viruses that have key loggers built-in or Facebook that tracks people's interest and monetizes that information. It seems that doing evil is fine as long as you can't get sued. Virus writers do it by being anonymous and Facebook does it by tracking your habits and selling them to the highest bidder. Virus removal software has been around for a while; and now we have something stops Facebook from abusing cookies. The extension is called On-Demand Cookie Cleaner - and it stops websites from tracking your identity. Maybe having your password stole is worst then being manipulated, but is it really? Both gave out info you really didn't want to give out. Go ahead and install the extension, your future self will thank me.
