ShareMeNot is a FireFox add-on that prevents sharing buttons embedded by websites from tracking who you are until you actually interact with the buttons.
With all the privacy concerns about third-party tracking — especially the one employed by Facebook — ShareMeNot offers a painless solution to websites tracking you when you don’t want it.
The main concern is that, even though many sites gather information anonymously, third-party tracking devices can be used to create a profile of your browsing habits, and even you as a person, through relentless information gathering.
There’s also Chrome version that’s still very much a WIP, but offers hope that something like ShareMeNot will be available for Chrome, too.
