What Is the Best Browser for Privacy and Security?

Web browsers are our gateway to the internet, where we can do just about anything, from buying gifts to video-chatting with grandma. But just like a physical gate, unless it’s secure, your web browser may be vulnerable to break-ins. Learn why some of the most popular web browsers aren’t necessarily the safest and how a dedicated secure browser will protect your privacy the most.


First, we’ll look at the most well-known browsers — including Chrome, Safari, and Firefox — and compare how they keep your private information safe and where they fall short.

Then, we’ll look at the best browsers for privacy and the features they offer to keep your browsing private and secure.

    Are you being tracked by your web browser?

    If you’re using any of the leading web browsers, you’re almost certainly being tracked. Browser tracking lets websites and companies follow your activity on the web and gather insights into your preferences, and it’s almost as ubiquitous as web browsers themselves. But there are browsers that don’t track you. 

    Here, we’ll review the most popular web browsers — and a few lesser-known, security-focused browsers — and see how they stack up in terms of both privacy and performance.

    The problem with the leading web browsers

    The leading browsers have earned their status largely because they’re easy to use, offer a clean design and interface, and allow for fast web browsing speeds. These features keep people coming back to the same browsers again and again. 

    But the leading browsers are also owned by some of the largest tech corporations around — Apple, Google, and Microsoft, especially — and these companies don’t always prioritize data privacy and security.

    In fact, web tracking happens on all the leading web browsers, and advertisers take note of every site you visit, using browser fingerprinting and other techniques to gather insights and serve you targeted ads.

    And, because the leading browsers are so well-known, they can be vulnerable to attacks such as browser hijacking. So, what’s the most secure web browser, really? We’ll break it down below.

    Popular browsers conduct web tracking using cookies, IP address tracking, and more.Web tracking is ubiquitous in the most popular browsers.

    Is Google Chrome safe?

    Google Chrome has been the most popular browser for a while now. Chrome is fast and convenient, especially for people with Google accounts, because it offers easy integration with other Google products and services. But with so many people using Chrome, can the web browser really be very secure?

    To be sure, Google updates Chrome frequently, making it difficult for would-be hackers to keep up with the company’s advancements. Using Chrome’s default safe browsing protections keeps some dangerous websites and phishing attacks at bay.

    But to get more robust protection, you need to agree to send Google your browsing data, which might make some people a bit queasy. 

    In fact, the company pioneered practices such as online tracking, targeted advertising, and mass data collection, techniques that are nearly impossible to shake today.

    Among Chrome’s less secure features, third-party cookies are permitted by default, and there’s no built-in ad blocking protection. So, for more security, you’ll have to add extensions — and some browser extensions are not as safe as they claim to be.

    So, while Chrome may be fast and convenient, it isn’t the best browser for security and privacy. If you have a Google account, you’re automatically signed in on Chrome, linking all your browsing activity with your Google account. This is convenient, but it gives Google even more data to use for targeted advertising and other purposes.

    You can take back some of your privacy by changing the settings in both Chrome and your Google account, and by adding safe and secure browser extensions. But if privacy is your primary concern, you should switch to a dedicated secure web browser.

    Is Safari a safe browser?

    Thanks to the widespread adoption of mobile web browsing, Apple’s Safari browser now has the second-largest market share of all browsers worldwide

    In terms of security, Safari is a more secure web browser than Chrome. Third-party ad tracking cookies are blocked by default, and Safari also prevents cross-site tracking, in which advertisers follow you from one page to another to learn more about your behavior and preferences. 

    But there’s no ad blocking software built into Safari, so if you’re looking for an ad blocker for your iPhone, third-party browser extensions will have to do the job.

    Safari also boasts a password-management feature, which generates new passwords for you and stores them in your iCloud Keychain. Keychain protects your passwords with 256-bit AES encryption. While this level of security isn’t matched by other leading browsers, you should be cautious when saving passwords in any browser.

    Safari uses Google’s Safe Browsing lists to ensure that you stay away from malicious sites. But this means you have to send your browsing data to Google. So if you’re using Safari instead of Chrome, you could still be tracked by Google.

    Unfortunately, if you want to use Safari but don’t have an Apple device, you’re out of luck, because Safari is compatible only with Apple devices. Those of us with Android phones or Windows PCs will have to use another browser. Thankfully, there are plenty more.

    Is Firefox safe?

    Mozilla, the maker of Firefox, has long advocated for more privacy, security, and transparency. Firefox browser, as an open-source web browser, has always been free for anyone to inspect, which has helped make it one of the more secure browsers around. While Firefox has lost a lot of ground to Chrome recently, it remains the most popular third-party browser globally. 

    When comparing Firefox to Chrome in security, Firefox has a few features in its favor. Thanks in part to its open-source software base, Firefox issues frequent security updates to improve performance and help foil hackers and other cybercriminals

    Firefox also gives users control over quite a few privacy settings, such as protections against tracking and browser fingerprinting. Firefox is a safe browser for privacy, but for more robust features like HTTPS encryption or ad blockers, you’ll have to install third-party extensions

    And Firefox still tracks you, unless you don’t grant it permission to send data back to Mozilla headquarters. For stronger protection, you’ll need to manually adjust your settings.

    Is Opera browser safe?

    While never the most popular browser, Opera has long been part of the browser game. The browser even pioneered many of the features we now take for granted, such as browser tabs. Opera was also the first browser to introduce built-in pop-up blocking — another feature that we’d be hard-pressed to live without today.

    These features (and more) make Opera one of the safest browsers to use. Its browser security suite includes several tools to help protect you online, like an integrated proxy (not a true VPN) that can hide your IP address, built-in ad blocking, and a database of malicious websites that are flagged before you cross into their treacherous territory.

    But none of this stops Opera from helping itself to your data. While you’re on the browser, Opera may collect information about your device and activity, and then use that data to optimize advertising campaigns, improve its product line, fix bugs, and so on.

    Is Microsoft Edge safe?

    Microsoft Edge has replaced Internet Explorer as the default browser on all Windows devices. Edge currently runs on Chromium, the same browser kit developed by Google that powers Chrome and other browsers.

    With weekly automatic software updates, Microsoft Edge stays on top of any security issues — making it a far safer browser than its predecessor, Internet Explorer. Edge’s integrated tracking protection feature helps safeguard your privacy online and shield you against third-party advertisers. 

    But Edge may send information about your device — and other data — over to Microsoft, which may use it for advertising or other purposes.

    To browse more privately, it’s time to switch to a private browser

    For more privacy online, you can adjust the settings of your preferred browser. Web browsers usually have options to modify privacy settings so that you can prevent tracking, for example, and make your browsing more secure. 

    To minimize tracking further, you can clear your website cookies after every session, or disable cookies altogether — though this will affect your browsing experience, as some websites don’t work well without cookies. 

    Finally, if you use private or incognito browsing, closing your browser window frequently will ensure that tracking cookies are cleared immediately, and that they don’t accumulate.

    But all these manual adjustments may be difficult to manage. Switching to a more secure, truly private browser will automate these processes, so you have more time for what you really need to do.

    Avast Secure Browser features a built-in privacy and security suite, complete with ad blocking functionality, anti-phishing and anti-tracking capability, and automatic HTTPS encryption — so there’s no need to set it all up yourself! 

    And Avast Secure Browser offers tons of other features you can easily toggle on or off depending on your needs, such as a privacy cleaner that clears your browser history and cookies with just a single click.

    What is a secure browser?

    A secure browser is equipped with features that keep your information safe and private by default. With a secure and private browser, there’s no need to adjust your privacy settings, because the built-in security tools include features like automatic encryption, ad blocking, anti-tracking, and alerts for unsafe websites. 

    Secure browsers can work well on mobile devices, too, so you can surf the web more securely regardless of what kind of device you’re on.

    Which is the best browser for privacy?

    While Chrome, Safari, and Firefox may be among the most popular web browsers, they’re hardly the most secure. For the most secure browser, you’ll need to look beyond the leading browsers. Below is a list of the best private browsers with features that will keep you truly private and secure online.

    The free, cross-platform Avast Secure Browser was built from the ground up with your privacy and security in mind. Like Chrome and Microsoft Edge, it’s also based on Google’s open-source Chromium model, but with a ton of additional security and privacy features built-in.

    Avast Secure Browser

    Built on top of Chromium, Google’s open-source software platform, Avast Secure Browser rivals the leading browsers in terms of speed and efficiency. But unlike the less secure browsers discussed above, Avast Secure Browser comes with an array of security and privacy tools built right in.

    Anti-phishing detection alerts you immediately if malicious websites are trying to steal your data or infect your device with malware. Avast Secure Browser also has powerful anti-tracking features that prevent websites and advertisers from identifying you through cookies or other web tracking methods. 

    And with advanced anti-fingerprinting technology, this dedicated privacy browser will ensure that your unique device and browser profile is never accurately captured.

    Additional features such as Bank Mode protect your sensitive financial information. And you’ll be notified immediately if any of your data is compromised or has been exposed in a data breach. 

    What’s more? Avast Secure Browser also encrypts your data with automatic HTTPS protection, even for websites that don’t offer it. Start using Avast Secure Browser today, completely free, and enjoy the peace of mind of a properly secure browser.

    Tor Browser

    Built to access the Tor network — a system of proxy servers that encrypt and redirect traffic to conceal users’ identities online — Tor Browser prioritizes privacy above all else. This makes it one of the most secure browsers around, but it does come at a cost — namely, usability and convenience.

    Tor Browser hides your identity while you browse the Tor network, which already comes with several layers of encryption. The browser doesn’t store your browsing history, deletes cookies after each browsing session, and disrupts browser fingerprinting. It’s also equipped with extensions that reinforce privacy and security, including automatic HTTPS encryption. 

    But because the Tor Browser’s features are so finely tuned, additional extensions or settings adjustments can compromise your security. While Tor Browser’s privacy protections are formidable, even the most secure fortress has weak points. 

    While using Tor, it’s still possible for your usernames and passwords to leak, and other people may still be able to monitor you through your ISP (internet service provider) or home Wi-Fi network. And due to the Tor network’s complex process of encrypting and redirecting traffic through proxy servers, you may find Tor Browser too slow for everyday use

    Moreover, unless you set up a VPN and connect through that first, your ISP will be able to see that you’re using Tor. And since many ISPs and governments view Tor simply as a means to access the dark web, you might have even more difficulties later on.


    Brave, another open-source web browser, is also built on Google’s Chromium platform. By default, the browser blocks ads, cookies, and other trackers, and disguises your device against browser fingerprinting. You can customize security and privacy settings for specific websites, and Brave also features an integrated Tor mode (though this is still being developed).

    Other features include a password manager and HTTPS encryption. Notably, Brave offers the opt-in Brave Rewards system, in which users accept (non-targeted) ads while browsing in exchange for supporting their favorite websites and content creators. 

    But Brave has fewer extensions than its competitors, even though some, like a password manager, certainly help reinforce security. Unfortunately, on some websites, Brave doesn’t work quite as seamlessly as you might expect, which muddies the web browsing experience.

    What if I’m browsing incognito?

    All of the browsers on our list include an incognito (or private) browsing mode. But private browsing isn’t the same as anonymous browsing.

    Private browsing, an optional feature within all the leading browsers, keeps your browsing history and details off the device you’re using, but it doesn’t control who or what collects your data on the other end. When browsing privately, your IP address and activity can still be tracked by third-party websites. 

    Private browsing may keep you a bit more secure, but going incognito doesn’t prevent you from downloading malicious files or offer you any extra security when making online payments.

    In some ways, “private” is a bit of a misnomer, because while browsing in private mode your information is not all that private.

    Anonymous browsing is more secure, because it obscures your personal details and activity from anyone or any site trying to track you online. Identifying information such as your IP address is anonymized, making it much harder for third-party websites to track you. 

    So, if you don’t want to be tracked, making your browsing anonymous is the way to go. While most browsers can’t keep you completely anonymous, tools such as a proxy server or VPN can help anonymize your online activity. 

    A VPN hides your IP address and encrypts your connection so that personal information, such as your location and browsing activity, remains hidden from advertisers and others hungry for your data.

    VPNs also protect you when you’re using public Wi-Fi, so if you use public networks often, give yourself extra privacy protection with a VPN.
