Improve your privacy with these excellent Firefox add-ons.
Stop Tracking with "Privacy Badger"
Privacy Badger is a browser add-on that stops advertisers and other third-party trackers from secretly tracking where you go and what pages you look at on the web. Privacy Badger learns about trackers as you browse by inspecting external resources websites request. Please be aware that Google Analytics is considered first-party by Privacy Badger, which means that Google Analytics will not be blocked if you do not use another blocker, such as uBlock Origin.
Block Ads and Trackers with "uBlock Origin"
An efficient wide-spectrum-blocker that’s easy on memory, and yet can load and enforce thousands more filters than other popular blockers out there. It has no monetization strategy and is completely open source. We recommend Firefox but uBlock Origin also works in other browsers such as Safari, Opera, and Chromium. Unlike AdBlock Plus, uBlock does not allow so-called “acceptable ads”.
Automatically Delete Cookies with "Self-Destructing Cookies"
Automatically removes cookies when they are no longer used by open browser tabs. With the cookies, lingering sessions, as well as information used to spy on you, will be expunged.
Encryption with "HTTPS Everywhere"
A Firefox, Chrome, and Opera extension that encrypts your communications with many major websites, making your browsing more secure. A collaboration between The Tor Project and the Electronic Frontier Foundation.
Block Content Delivery Networks with "Decentraleyes"
Emulates Content Delivery Networks locally by intercepting requests, finding the required resource and injecting it into the environment. This all happens instantaneously, automatically, and no prior configuration is required. Source code: GitHub.
The following add-ons require quite a lot of interaction from user to get things working. Some sites will not work properly until you have configured the add-ons.
Stop cross-site requests with uMatrix
Many websites integrate features which let other websites track you, such as Facebook Like Buttons or Google Analytics. uMatrix gives you control over the requests that websites make to other websites. This gives you greater and more fine grained control over the information that you leak online.
Be in total control with "NoScript Security Suite"
