Did you know that buttons like these allow Facebook, Google, LinkedIn, and others to track your online browsing activities on every site that includes one of these buttons, even if you never click the buttons and (in some browsers) even if you have third-party cookies disabled?

ShareMeNot is a browser extension designed to prevent third-party buttons (such as Facebook's “Like” or Twitter's “tweet” button) embedded by sites across the Internet from tracking you until you actually click on them. Unlike traditional solutions, ShareMeNot does this without completely removing the buttons from the web experience.

Note that this extension is part of a research project and not targeted for general use. We welcome your feedback and will use it to improve our tool.

As of July 20, 2014, ShareMeNot is no longer being maintained as a standalone tool.

We're excited to announce that we have incorporated ShareMeNot's functionality into the Electronic Frontier Foundation's Privacy Badger tool, and we recommend that all ShareMeNot users transition to using Privacy Badger.

Thank you for your continued interest in and support of ShareMeNot!
