Mozilla released a browser extension aimed at blocking Facebook from tracking users on sites operated by other companies, reports Digital News Daily, which added that “Rather than stop using a service you find valuable and miss out on those adorable photos of your nephew, we think you should have tools to limit what data others can collect about you,” Mozilla says Tuesday in a blog post explaining the new “Facebook Container” extension.

“The tool deletes users’ Facebook cookies and logs users out of the social networking service. When people who have downloaded the extension visit Facebook, the social networking service’s page will be opened in a new “container” tab. If those users then click on non-Facebook links, the extension opens a new page, outside the “container.”

“The extension will prevent Facebook from tracking people via social widgets or other methods that rely on cookies. But it won’t prevent developers like Cambridge Analytica from accessing data that users have shared with Facebook. Mozilla says the tool can nonetheless help people “protect themselves from the unexpected side effects of their usage.””
