The Best Browser Extensions for Privacy and Security 2026

Browser extensions can not only enhance your browsing experience but also improve your privacy while you browse. A virtual private network (VPN) like Surfshark can mask your IP address to protect you from unsafe networks and hide your online activity. Ad blockers like Total Adblock block more than just ads — they can also block trackers from collecting your data.

We’ll cover various types of browser extensions, including VPNs, antivirus software, and even free services that can help you maintain your privacy and security online.

Best VPN extensions

If you use a virtual private network (VPN) or are interested in incorporating one into your online security arsenal, we have some recommendations for browser use. A VPN is designed to provide a secure, private internet connection and to hide your IP address. Many people who travel use VPNs because they help ensure hackers cannot access their information.

Even if you don’t travel, a VPN is good protection for your home network or when you use public Wi-Fi. Since public networks are not secure, a VPN can mask your internet traffic. We’ve gathered a few of the best VPN browser extensions for your consideration.

Surfshark

You’ll get a quality VPN with Surfshark. It’s secure, thanks to features like a kill switch, and comes with extras like smart DNS. A kill switch is a nice feature that lets you disconnect your device if your VPN connection drops. Smart DNS lets you access content that may not be available in your area and can be used on smart devices. 

It also offers unlimited device connections and is compatible with numerous browsers, including Chrome, Firefox, and Edge.

We must mention that Surfshark is also headquartered in the Nine Eyes alliance territory. These are countries that have agreed to share information, meaning that some of your internet activity may be tracked and recorded for their use.

NordVPN

With NordVPN, you get high security and fast internet connection speeds. It uses AES 256-bit encryption to keep all your information secure. If you’re looking for an interface that’s easy to use but still includes lots of features, NordVPN won’t disappoint. You’ll get access to a large network with over 6,000 servers, and it works with popular streaming platforms like Hulu, Disney+, BBC iPlayer, and more.

There’s no need to worry about compatibility either, as this VPN has extensions for Google Chrome, Mozilla Firefox, and Microsoft Edge.

However, Nord offers several plans but no free option. And to get the lowest monthly price, you must pay for one year of service in advance, which could be steep. If price is a concern, other providers like Surfshark may be a better choice.

ExpressVPN

ExpressVPN is a popular VPN that offers fast speeds and an intuitive interface. It also works with different streaming services like Netflix and Hulu. There’s no shortage of compatibility options: ExpressVPN supports multiple operating systems, smart devices, and browsers, including Chrome, Firefox, and Edge.

The downside to ExpressVPN is that it’s a little pricey. Plans start at $3.49/mo, which is more than Nord and Surfshark. It’s also missing a few features we’d like, like malware and antivirus protection.

Best password manager extensions

If you’ve never used a password manager, you may be missing out on important data security. A password manager can store your login credentials securely while keeping a record of your usernames and passwords. Many also store credit card numbers and bank account data. Password managers are good for cybersecurity because most use encrypted storage to prevent hackers from accessing your data and compromising your online safety.

NordPass

From the makers of NordVPN, NordPass can organize your login credentials, credit cards, safe notes, and more. It includes multiple-factor authentication options for added security, such as authentication apps, security keys, and backup codes, to keep all this information safe. 

NordPass has extensive compatibility, with extensions for Chrome, Firefox, Safari,  Edge, and Opera. 

However, the free plan lacks features like password health to identify weak passwords, data breach scanning, and emergency access. Otherwise, we're pretty impressed by NordPass. 

RoboForm

RoboForm has a free version and paid-tier plans. If you get the free version, you’ll have access to features like unlimited password storage, autofill, and a password generator. The paid plans start at $1.59/mo, and they include extras such as access across all devices, the ability to grant and receive emergency access, and complete password-sharing capabilities.

RoboForm's only drawbacks may be its hard-to-read privacy policy and customer support. The policy webpage uses plain text, making it difficult to parse. We also found customer support to be limited, especially for the free plan, and slow to respond.

Keeper

This password manager works with almost any browser. User data is stored in one vault to keep everything private and secure. Like some other options, Keeper lets you store credit card and banking information. It also includes a security audit feature that shows whether the software considers your password strong enough.

If you’re looking for the downside to this software, it may take some time to learn the interface. Also, the autofill extensions may not always work, and that can be a drag if you’re in a hurry. The pricing is reasonable, though, starting at $2.92/mo for the one-user plan.

Best ad and tracker blocker extensions

Have you ever wanted to browse the internet anonymously? You might like to rid yourself of those intrusive ads that seem to pop up out of nowhere. Ad and tracker-blocking tools can remove those ads and protect your online privacy.

Total Adblock

With Total Adblock, you get plenty of features, like security from malicious websites and unwanted ads. The software also lets you manage trusted websites and whitelist sites you want to support. 

It’s compatible with some of the most widely used web browsers, including Chrome, Edge, and Firefox, and offers an option for iOS and Android devices.

The free version of Total Adblock excludes the top 15,000 websites, so that may not help you block many ads. While using the free version, some users reported frequent pop-ups encouraging an upgrade to the Premium plan, which can be annoying.

AdGuard

The AdGuard extension works on desktops, laptops, and mobile devices. It also works on multiple platforms, so compatibility is not an issue. If you want a modern interface with software that focuses on private data security, AdGuard is a top product. It also works well for blocking intrusive ads on YouTube and Facebook.

AdGuard is compatible with Chrome, Firefox, Safari, Edge, Brave, and Yandex.Browser. However, you must use the desktop app rather than the extension to get the most functionality out of the product. This might make some hesitant to download the extension. For instance, if you want faster page loading times, you’ll need the desktop app. The AdGuard welcome page also mentions the extension's partial functionality, which isn’t encouraging.

Best antivirus extensions

If you don’t use an antivirus, what are you doing with your online life? In all seriousness, antivirus software has become a necessity, with over 450,000 new malware pieces detected every single day. You don’t want to take chances with your internet security, which means you want the best antivirus with the features you need most.

McAfee WebAdvisor

McAfee has been the tried-and-true standard for many years. You likely won’t find anyone who hasn’t heard of this antivirus. 

Its browser extension, McAfee WebAdvisor, also includes antivirus software and provides extra browsing security. It blocks malware and phishing sites, giving you more peace of mind while online. 

If you don’t want to purchase an entire antivirus suite, that’s not a problem. You can download McAfee WebAdvisor for free.

Norton Safe Web

Since the internet is a sea of possibilities, it also harbors many threats, such as malicious websites, computer viruses, and spyware. All Norton plans with device security include Norton Safe Web, a browser extension that lets you know how safe a website might be before you even access it. The browser extension analyzes the sites you visit to provide safety ratings.

Norton Safe Web also comes with online banking protection and phishing protection. It’s compatible with Chrome, Firefox, and Edge. 

Bitdefender Traffic Light

Made by the popular Bitdefender antivirus, Traffic Light is a browser extension that provides extra security while online. It’s a free extension that blocks malicious website pages and phishing attempts. It also identifies trackers so you can be aware of pesky websites tracking your online activity. 

Bitdefender Traffic Light works with multiple browsers, like Safari, Google Chrome, and Firefox.

Best free extensions

If you’re on a budget and don’t want to buy a browser extension, you’re in luck. Some free products are still good at protecting your web browsing. These options prove that the best ad blockers don’t always come with a hefty price tag.

uBlock Origin

If you’ve ever watched your web browser begin to drag, you know the frustrations of many users. It happens often, especially when numerous tabs are open. We like uBlock Origin because it is designed to optimize memory and CPU usage. That’s a feature many want because it allows for faster page loading time and easier, smoother scrolling.

If that isn’t enough, it’s also promoted as a “wide-spectrum content blocker,” which means it has plenty of features to make you happy but won’t overwhelm you while it does so. You can download uBlock Origin for Chrome, Firefox, Edge, and Opera for free.

If there’s anything negative to report, it might be that uBlock Origin could potentially interrupt other security extensions. It is open-source software, so some features require technical knowledge that all users may not possess. We have to give the designers credit, though. These areas will indicate that they’re only suitable for technical users, so you know before you go!

Adblock Plus

Adblock Plus is an ad blocker that is compatible with most platforms, including Chrome, Firefox, Edge, Safari, and Opera. It also works with iOS. Adblock Plus helps speed up page loads because you won’t have to deal with annoying ads that bog down the browser. You’ll also get a whitelisting feature so you can still support the websites you enjoy while blocking ads from other sites.

A potential issue some users have with Adblock Plus is that you need a paid subscription to block videos and to avoid receiving survey requests. There are also fewer features for Safari.

Ghostery

Ghostery will prevent websites from tracking your online adventures. It won the 2018 SXSW Interactive Innovation Award for Privacy & Security because of its high ratings.

Ghostery comes with whitelisting and blacklisting options so you can support your favorite creators and block websites you deem unsafe. You can use Ghostery on most platforms, including Chrome, Firefox, Safari, Opera, and Edge. It also has an app extension for iOS and Android devices.

You may want to be cautious when using the extension with Safari, as the performance may be weaker than with other browsers. It’s also not available on Chrome for Android. Otherwise, you get plenty of features for free with this browser extension.

1Blocker

Many Mac users find that security products either don’t work well for Apple devices or leave certain features exclusive to Windows. 1Blocker is an ad blocker for macOS and iOS that appeals to Apple fans. You can customize what kinds of ads, widgets, and comments you see when you’re online. It was built exclusively for Safari and includes a firewall. It’s also fantastic for parents because you can even block adult sites.

The only downside to 1Blocker may be that there are no smart toggles for Safari on iOS, and some app functions didn’t work as well using the ad blocker when we tested it.

How to add extensions to your browser

Now, you should learn how to add them to your current web browser. Of course, these steps may vary by browser, but there are some basic steps.

For this example, let’s say you want to add a Chrome extension. Here’s how easy it is to get up and running:

1. Open the Chrome Web Store.
2. Look for the Chrome privacy extension you want.
3. Click Add to Chrome. If the extension asks for permission, grant it.
4. Click Add extension.

That’s how simple adding an extension is for most browsers. You may need to adjust your privacy settings to give the browser access, but that’s not a hassle and only takes a few seconds.

Bottom line

By now, you see there are numerous extensions available to keep your data private and secure while you’re online, including VPNs, password managers, ad and tracker blockers, and antivirus software. The challenge is deciding which browser extensions you may want to try first, but you can't go wrong with any of the options on this list.
