Select “Tell websites I do not want to be tracked” – this will tell advertisers your tracking preference
Below that, you can decide which cookies to accept, and for how long
Add exceptions to cookie-blocked sites if needed
You can also block cookies from third party advertisers by subscribing to “block” lists. Select “Tools” again, and then “Add-ons”
Mozilla Firefox offers many Add-ons to protect user privacy. Here are some of the most popular Add-ons.• Ghostery blocks the invisible tracking cookies and plug-ins on many web sites, shows it all to you, and then gives you the choice whether you want to block them one-by-one, or all together.• Adblock Plus stops social networking sites from transmitting data about you after you leave those sites, even if the page you visit has a social plugin on it.• Do Not Track Plus is the Do Not Track app that sends a request to websites not to track you, with a “plus” of also stopping third-party data exchanges. So, when you visit a site with Facebook, Twitter and Google+ buttons on it, your browser will tell the network that youre on a site with those buttons, and no information will be sent until you choose to click one.• Priv3 is a new extension that will protect you from third-party cookies set by Facebook, Twitter, Google+, and LinkedIn. Like Do Not Track Plus, it doesnt remove elements from a page—it simply makes them inactive until you interact with them.
Let’s use Adblock Plus for this example. In the “Get Add-ons” tab, type “Adblock Plus” in the search bar, and hit Return.
You can read more about each tool simply by clicking on it. To add the tool, click “Install” next to the tool you want. It will be installed once Firefox restarts.
For some tools, such as Do Not Track Plus, icons will appear in the top right corner after you add them. You can use these icons to manage your tracking protection.
