There are a ton of browser extensions that promise to protect your privacy, which leads to some natural questions: Which is the best? Do they all do the same thing? What should I really download? In this guide, we’re going to look at the most popular browser extensions that promise to protect your privacy online, and give you our recommendations.


We’ve talked about why you should care about your privacy several times here, so whether you choose to do something to protect yourself is up to you—we’re not going to rehash it. Instead, we’re going to dive into the tools available to keep your data safe. Don’t worry, though. You don’t need to download a ton of apps to keep yourself safe and your data close to pocket. Here are the best in each group.


Update: A lot has changed since we first published this post. We’ve refreshed it with new options in each category, removed dead extensions that are no longer available, and updated each section with new contenders and updated information. Our big picks are the same (AdBlock Plus for ad blocking and Disconnect for browser-based privacy,) but uBlock Origin is a great alternative to ABP that we encourage you to try out. Similarly, Disconnect still has its amazing browser plugins, but they also have a new premium package that’s worth discussing if you want whole-desktop and mobile privacy protection.

Block Ads, Scripts, and Popups with AdBlock Plus

Ad and script blockers give you control over your browsing experience. They can block ads on the sites you visit and kill third-party scripts and widgets that send your data to who knows where. However, with great power comes great responsibility: If you don’t know how to use them, these tools can break the sites you read, rendering them unusable until you figure out what to allow and what to block. Plus, blocking ads can has a very real impact on the site and the people who work on it (like us here at Lifehacker). Even so, it puts the power into your hands to decide which sites are worth supporting and which are just too annoying to use without an ad-blocker.

AdBlock Plus (Firefox/Chrome/Safari) blocks banner ads, pop-up ads, rollover ads, and more. It stops you from visiting known malware-hosting domains, and also disables third-party tracking cookies and scripts. Plus, there are a ton of things you can do with it beyond just blocking ads. We think it has the right combination of ease-of-use, on-and-off toggling, whitelisting capabilities, and hands-off management that makes it a tool that anyone can pick up and use. Power users can get their hands dirty with different subscription lists and tweaking the active lists they use, but basic users can enable it and walk away.


The Alternatives:

In our opinion, Adblock Plus is your best bet, but there are a few other extensions that do the same thing. Here are your other options:


We should say here that if you don’t use AdBlock Plus for some of those advanced features, like trimming YouTube’s cruft or blocking specific things, you should give uBlock Origin a try. It’ll do wonders for your browser’s memory consumption, and you’ll get a more powerful and customizable tool as a result—although you may need to do some tweaking to get it to work just the way you like it.


Stop Everyone from Tracking Your Browsing with Disconnect

Anti-tracking and anti-cookie extensions have exploded. We covered a number of them when we discussed how you can stop companies from tracking your movements on the web. Since then, the market has only grown, with more extensions and apps that all honestly do the same thing, with little more than UI tweaks and differences between them.


Disconnect Private Browsing (Firefox/Chrome/IE/Safari) is our pick because it protects you from tracking, malware, and malvertising, and offers secure Wi-Fi and bandwidth optimization features that just aren’t available in other tools. It blocks third party tracking cookies and gives you control over all site scripts and elements from a simple-to-use toolbar menu. When malware injects ads onto popular pages, or ad networks are hijacked by embedded malware, Disconnect can protect you from that as well—and it happens more often than you might think. It also protects you from tracking by social networks like Facebook, Google, and Twitter, which use your browsing even off-site to collect data about you. Finally, Disconnect protects you from sidejacking (or widgetjacking ), where an attacker can use stolen cookies to access personal data without having to know your password, with its Secure Wi-Fi feature.


The Alternatives:

Disconnect is our favorite of the bunch, but there are other extensions that do the same thing (or some of the same things) if you need alternatives:


You could argue that Disconnect, Do Not Track Me, and Ghostery all do the same thing, but we still think that Disconnect is the most robust of the three. We like Privacy Badger’s “learn as you go” approach, but we can’t argue that it leaves you with less protection out of the gate than any of the others here. That said, Disconnect’s newest version is only available for Firefox and Chrome, so if you prefer Safari, IE, or Opera, we’d suggest going with Do Not Track Me instead.


Some of this comes down to personal preference, what doesn’t break the sites you visit, and what works best in the browser you use most often, so don’t hesitate to try something else if one doesn’t work. The worst that can happen is you’re extra protected, and none of these add-ons have that much resource overhead.

Get Desktop and Mobile Protection with Disconnect Desktop


Disconnect’s browser tool is a must-download, and we recommend it for everyone who wants a little privacy—or even who wants to speed up their web browsing experience, since you’ll see noticeably faster page loading and browsing times once all of that tracking and advertising cruft is disabled. If you want to take things a step further though, Disconnect’s new whole-desktop package rolls in the Private Browsing features we mentioned above with a proxy and VPN that keeps all of your browsing safe. It checks your connections against Disconnect’s known list of malware-packed ad networks, third-party tracking tools, known malware hosts and sites, and more, and then just blocks it from ever resolving.


The free version of Disconnect’s desktop suite includes the browser plugins we mentioned above with Disconnect’s private search, and a basic proxy that keeps your browsing safe. If you upgrade to Disconnect’s premium offering ($5/mo or $50/yr) you get those features along with mobile apps for iOS and Android to protect your browsing and block malware and adware on the go (which also happens to block a lot of ads), a full-fledged VPN to encrypt your traffic (and to get around pesky location restrictions,) and more.

It’s a great service, and frankly there aren’t alternatives to this one because it’s such a holistic package. That said, the premium cost may be too much for some people. We definitely think you should subscribe to a VPN, especially when you’re on Wi-Fi or using untrusted networks, but Disconnect’s is designed for privacy and security, not necessarily anonymity or file transfer like others we’ve highlighted. Weigh your needs before opening your wallet. For many people, the Disconnect browser extensions are all the protection you’ll need, but there’s nothing wrong with supporting a project that’s keeping the web safer for all of us.


Additional Privacy Tools You Should Have



In addition to privacy protecting tools and ad blockers, a few other add-ons, utilities, and services came up while we were researching this piece that you shouldn’t roam the web without.


HTTPS Everywhere (Firefox/Chrome) is a must-have regardless of what other security tools you opt to use. Once installed, the extension will shunt your connection to SSL whenever possible, and will try to find secure versions of the sites you visit. It’s a great way to protect your browsing without really lifting a finger. Best of all, it just updated to keep you safe on thousands more sites around the web.


A Virtual Private Network (VPN) encrypts all of your internet traffic and offers the most possible protection from prying eyes. We’ve covered VPN services in detail before, including what to look for, what makes a good one, and some great providers to try. Look for a provider that keeps only the minimum required logs for troubleshooting purposes, offers strong encryption, is well regarded by its users, and offers multiple exits locations. Contrary to common belief, don’t just spring for any offshore VPN—just because your VPN provider is in a far-off country doesn’t mean it’s secure, or at all private. For more suggestions, our friends at TorrentFreak just updated their list of providers that take your anonymity seriously, and it looks a bit like ours. If you’re just looking for a free or freemium service to keep you protected while you’re out and about, and you’re not ready to try on a full, paid, VPN service yet (or roll your own), try Hideman or Tunnelbear.


Antivirus and Antimalware utilities are essential to protecting security. It may sound like “How to Internet : 101,” but taking care to avoid suspicious sites, practice good internet hygiene (eg, not opening suspicious attachments, checking file names before you download, etc), and keep updated antivirus and antimalware tools on your PC is important. Often the term “privacy” is couched in terms of advertising and marketing, but the risk of identity theft and getting infected with ransomware is growing. We’ve recently updated our pick for the best antivirus app for Windows, and we have some options for Mac as well. Looking for antimalware? These suggestions will get you started.


Other Security Tools You Probably Don’t Need, but May Want

We’ve covered the most important privacy and security tools you need already, but there’s always another step you can take to make sure your communications can’t be intercepted and read by third parties. Here are a few other tools you might consider:





Update: Web of Trust used to be on this list, but we’ve removed it after the company was caught selling the browsing histories and details of its users to third-party companies. If you currently use WoT, we recommend you uninstall it and stop using it immediately.


There’s a ton of overlap between a lot of these tools, which is why we wanted to trim the fat and pick specifics that we think you should install. Keeping too many on your system isn’t necessarily a bad thing, but it can slow your computer down at worst, and at best it doesn’t offer you any additional protection. If you’re not using any because you’re not sure which to use, now you have some solid options. Either way, the tools are at your fingertips. It’s never been easier to take the reins for yourself and make the web an opt-in experience instead of an opt-out one.
