Tor Browser: Best for anonymous browsing

Who it’s best for

Tor is ideal for individuals who prioritize anonymity online. It suits users such as journalists, activists, or anyone who needs to protect their identity due to the sensitive nature of their online activities. Those concerned about government surveillance or internet censorship also find Tor highly beneficial. Although it’s free, its advanced features cater to users with some technical know-how, making it less user-friendly for the general populace.

What we liked

We liked how Tor Browser excels in providing anonymity. It routes internet traffic through multiple servers worldwide, making it difficult for users’ online activities to be monitored or traced. This enhanced privacy, alongside having an open-source nature and availability in multiple languages, makes it accessible and trustworthy. The fact that it was built by the U.S. Naval Research Lab (NRL) to hide intelligence and is maintained by a non-profit organization also adds credibility to its security and privacy.

What we didn’t like

Despite its strengths, Tor Browser is not without drawbacks. It's notably slower than mainstream browsers due to its complex routing process for maintaining anonymity. Users might find this trade-off between speed and privacy challenging. Also, while Tor masks IP addresses effectively, it's not entirely foolproof, particularly at the network's exit nodes. Using Tor might raise legal concerns in some countries due to its association with accessing the dark web.

Opera: Best for built-in VPN features

Who it’s best for

Opera is a suitable choice for anyone looking to strike a balance between functionality and privacy. It’s great for those who want to avoid the technical complexities of more specialized privacy browsers. Opera offers a built-in virtual private network (VPN) feature, which is a significant advantage for those who also wish to use a VPN. This allows users to save money on the costs of a separate service. Opera is perfect for everyday users who value privacy and want a user-friendly, versatile web browser.

What we liked

The VPN is the standout feature we like about Opera. It offers a straightforward solution for users to gain enhanced privacy and security. Given that this built-in VPN is free and easy to use, it appeals to users new to VPNs who are looking for a hassle-free experience. We’re also a fan of the robust cookie management tools offered by Opera. They allow users to clear and manage browser cookies effectively to limit the spread of their information. It also boasts additional features like ad blockers and has a user-friendly interface.

What we didn’t like

One thing we do want to note is that the browser’s built-in VPN has some limitations. Although convenient, it isn’t likely to offer the same degree of protection or speed as a standalone VPN provider. It also doesn’t have as many server options, which can limit a user’s access to geo-restricted content. Users looking for more advanced privacy features may find that Opera is a bit basic compared to the browsers that are fully focused on privacy.

Mozilla Firefox: Best for customizable privacy controls

FellowNeko/Adobe

Who it’s best for

Mozilla Firefox is an ideal option for users who value privacy and flexibility. It offers various levels of cookie management and tracking protection, allowing users to tailor their privacy settings. This makes it a no-brainer for privacy-conscious individuals who want a personalized experience.

What we liked

Mozilla Firefox stands out for its robust and customizable privacy controls. It offers Enhanced Tracking Protection by default, blocking a wide range of trackers and harmful scripts. Users can further adjust these settings for more stringent privacy measures. We like how Firefox disables browser cookies and blocks third-party trackers. Its no-cost nature, user-friendly interface, and compatibility across various platforms also make it accessible to many. Finally, its open-source nature adds a layer of transparency and trustworthiness, which is essential when looking for a browser. Firefox now also includes a free, built-in VPN that runs on Mullvad’s infrastructure. In our testing, it passed WebRTC and IP/DNS leak tests with only a 10% to 15% speed drop, though it protects browser traffic only and lacks a kill switch or server selection.

What we didn’t like

One downside to Firefox's extensive privacy features is that they can sometimes break websites or hinder the internet browsing experience. This occurs when essential cookies or scripts are blocked. Some users might find the customization process slightly complex. While Firefox is a strong contender here, it may not offer the same level of integrated security features as other specialized privacy browsers.

Mozilla Firefox pros and cons

DuckDuckGo: Best mobile browser for privacy

Timon/Adobe

Who it’s best for

DuckDuckGo is most beneficial for mobile users who prioritize privacy over everything else in their internet browsing experience. It's especially appealing to those wary of being tracked online by advertisers and data brokers. DuckDuckGo is designed for users who want simple, straightforward privacy features without any cost. It's a great choice for individuals who prefer web browser privacy without a complex setup or additional fees.

What we liked

DuckDuckGo shines for its commitment to not tracking users' search history and to maintaining privacy across web activities. Its straightforward privacy controls, such as the tracker blocker and Fire button for erasing browsing data, enhance user security without compromising ease of use. The private search engine's ability to block third-party trackers and ads organically is a significant plus, contributing to a cleaner and more private browsing experience.

What we didn’t like

A notable limitation of DuckDuckGo is that while it blocks trackers, ads based on search results still appear. Although not personalized, these ads might still be a concern for users seeking an ad-free experience. Additionally, some features, such as “bangs,” can undermine the privacy benefits DuckDuckGo offers by leading to search leakage.

DuckDuckGo pros and cons

Mullvad Browser: Best for WebRTC Protection

Who it’s best for

Mullvad is particularly beneficial for users who prioritize WebRTC protection, essential for safeguarding against IP address leaks during real-time communication. It's ideal for individuals who frequently engage in video conferencing, make VoIP calls, or use P2P services. Its emphasis on privacy, without requiring personal information at sign-up, makes it a top choice for those seeking anonymity. While it's free as a browser, its associated Mullvad VPN service offers competitive pricing, appealing to users mindful of cost and privacy.

What we liked

Mullvad Browser stands out with its robust WebRTC protection, ensuring that users' real IP addresses are not exposed during web sessions. Its partnership with the Tor Project to develop a privacy-focused browser demonstrates its commitment to online anonymity. The browser's simplicity and user-friendly approach make it accessible to many users, irrespective of their technical expertise.

What we didn’t like

One concern is the browser's potential lack of integration with certain mainstream features or extensions that users might be accustomed to in more popular browsers. This might limit its appeal to a broader audience. Users familiar with more feature-rich browsers might find Mullvad's simplicity and focus on privacy a trade-off against functionality and customization options. It's also important to note that while the browser is designed for privacy, it does not inherently include all the features of a VPN service, which some users might expect. That comes at an additional cost.

Mullvad pros and cons

Brave: Best for built-in ad and tracker blocking

Adobe/Photo Agency

Who it’s best for

Brave is a great fit for everyday users who want strong privacy without installing extra extensions. It's built for people who are tired of ads and trackers following them around the web, but don't want the technical setup required by a browser like Tor. Because it blocks ads and trackers automatically on both desktop and mobile, it's also a smart pick for anyone who wants a faster, cleaner browsing experience out of the box.

What we liked

Brave comes with a built-in ad and tracker blocker that works on desktop and mobile, blocking most ads (including YouTube pre-roll and mid-roll ads) automatically, without a separate extension. It also sends a Global Privacy Control signal by default, telling sites not to sell or share your data, and Brave helped create the GPC standard alongside Mozilla and DuckDuckGo. It's free, available on iOS and Android, and offers private browsing with minimal effort.

What we didn’t like

Brave is built on Chromium, the same engine that powers Google Chrome, which may give some privacy purists pause. It also includes optional crypto-based rewards features that not everyone wants, though you can turn them off. And while Brave blocks trackers well, it doesn't offer the deep anonymity of a browser like Tor for high-risk situations.

Brave pros and cons
