The Worst Browser for Privacy—You're Probably Using It Now

As much as the internet has evolved over the past decade—with advancements like improved access to AI chatbots—one constant remains: the essential web browser. For many, the web browser is still the primary gateway to the internet. However, not all browsers are created equal, especially when it comes to online security.

Whether you're using the internet for work, school, or casual browsing, websites are constantly collecting bits of information about your online behavior. Some browsers do a better job than others at protecting your privacy, and one browser stands out as a major concern when it comes to user data.

Your choice of browser can have significant implications for your online privacy. To understand why, I spoke with Bob Gourley, a cybersecurity consultant and author of The Cyber Threat. Here's what he had to say about which browsers offer the best protection and which ones might be keeping an eye on your every move.

Which browser is the worst for privacy?

Arguably, the worst browser for online privacy is Chrome. This is largely due to the fact that it is owned by Google, a company whose business model revolves around behavioral profiling. “Chrome is built by a company whose entire business model is behavioral profiling,” says Gourley. “Everything you do in Chrome, from searches to dwell time to links you hover over, is tracked. Every page view adds another data point.”

Google thrives on data collection, and according to recent statistics, more than two-thirds of desktop PC users rely on Chrome as their primary browser. “Multiply that by 100 million users, and you’re looking at a surveillance system posing as a browser,” Gourley notes.

So why not use Incognito mode? Unfortunately, this doesn’t provide complete privacy. While Incognito prevents your browser from storing browsing history on your device, it doesn’t stop websites from gathering data such as your IP address or interaction metrics. It also doesn’t necessarily stop Chrome from collecting data in the background.

“The more you poke at Chrome, the more you’ll find it still works behind the curtain in private mode,” Gourley explains. “It will continue to tie any browsing activity back to your Google account unless you disallow it. Everything—bookmarks, IP range, and autofill info—is recorded.” While Incognito isn’t entirely useless, it shouldn’t be relied upon for total privacy. It’s best to stay logged out of your personal Google account when using it.

What sort of data does Chrome collect?

While it's difficult to know exactly what data Chrome collects, the list is extensive. Here are some of the types of data that Chrome gathers:

• Browsing history
• Search queries
• Bookmarked websites
• IP address (including your approximate geographic location)
• Saved usernames and passwords
• Autofill information, such as addresses
• Device information, such as hardware model and operating system
• Usage and interaction metrics (including ad activity)
• Synced data across multiple devices

When collected over time, this metadata allows Google to build a user profile, effectively creating a "digital fingerprint" that includes your browsing habits, purchasing behavior, and even personal details related to your health or social life.

What does Chrome do with the data it collects?

While some of the data Chrome collects is used to improve user experience—such as auto-filling forms or providing helpful search suggestions—not all of it is benign. One of the main purposes of building these profiles is to serve targeted advertisements, a practice that, while legal, raises ethical concerns. Targeted ads can be useful, but many users feel they infringe on their privacy.

More troubling is how this data is shared with third parties, such as advertisers and data brokers. There is an entire industry built around selling this kind of information. Although primarily used for marketing, it's a legitimate concern for anyone who values online security and privacy. In fact, some users have taken legal action, including a class-action lawsuit against Google.

What are the best browsers for privacy?

The good news is that you don't have to stick with Chrome. There are several great alternatives that offer stronger privacy protections. Here are a few browsers worth considering:

Brave

Brave is a top-rated browser designed to protect your privacy and reduce online annoyances. Unlike Chrome, Brave doesn’t collect any personal data. It may collect anonymous usage statistics for things like crash diagnostics and telemetry, but it gives you the option to disable this. It features built-in ad blocking and blocks other privacy threats, such as cross-site trackers and browser fingerprinting. You can also block cookies and scripts altogether, although this may interfere with some website functions.

Another benefit of Brave is that its code is based on Chromium, making it compatible with most extensions that work with Chrome. Despite this, it doesn’t compromise your privacy like Chrome does. It even has a built-in Tor mode, allowing you to browse the web privately through the Onion Router.

I’ve been using Brave for years, and it’s my favorite browser. It takes privacy and security seriously, is user-friendly, fast, and responsive. It also works seamlessly with the extensions I use. In some cases, you may need to tweak privacy settings if Brave’s controls cause issues with certain websites, but this is rare.

Tor Browser

For maximum privacy, the Tor Browser is an excellent alternative to Chrome. Built around the Tor network, this browser hides your IP address and location by routing your traffic through multiple proxy servers worldwide. It also prevents browser fingerprinting, making it harder for websites and advertisers to track your activity.

However, the Tor Browser is not ideal for everyday use. It can be slow due to the multiple nodes it routes traffic through, and some websites block Tor exit nodes. It’s best suited for sensitive tasks rather than casual browsing.

Firefox

Firefox, though not as popular as Chrome, is a strong choice for privacy-conscious users. As an open-source browser, it offers robust privacy controls, including tracking protection and anti-fingerprinting features. However, it doesn’t offer the same level of privacy out of the box as Brave. You may need to install add-ons like uBlock Origin and HTTPS Everywhere for enhanced protection.

Firefox is also less fast than Brave, which is something to consider if you're using an older device. Additionally, privacy add-ons available for desktop browsers are often not available on mobile devices.

What’s the best way to keep your personal info private while browsing?

The easiest way to protect your privacy is by choosing the right browser. “If you care about your data being yours, use a browser that doesn’t send a report back to HQ every time you check the weather,” Gourley advises. “Tor, Brave, and Firefox aren’t perfect, but they don’t surveil your browsing habits to sell you ads.”

In addition to choosing the right browser, there are other practical steps you can take to enhance your online privacy:

• Use different browsers for different tasks (e.g., work vs. personal use).
• Use a privacy-oriented search engine like DuckDuckGo or Startpage.
• Use a VPN when traveling or on public Wi-Fi.
• Use strong, unique passwords for your accounts.
• Enable multifactor authentication (MFA) on sensitive accounts.
• Keep your browser updated regularly.

If you've been using Chrome since its release in 2008, switching to a more privacy-focused browser may seem daunting. But it's the best way to ensure your private information stays private. Plus, you can easily import your passwords, bookmarks, and extensions into your new browser, so you won't have to start from scratch.
