Browser Security Guide

Which Browser Should
You Be Using?

Your browser is the window through which you see the internet — and the window through which the internet sees you. Choosing the right one, and using a separate browser for sensitive activities, is one of the most effective steps you can take to protect your privacy.

The Browser Separation Strategy

Security experts recommend using two different browsers for two different purposes. This is one of the simplest and most effective privacy techniques available.

Primary Browser
Everyday browsing

Use for general browsing, news, social media, and shopping. Should be privacy-focused but fast and compatible.

Brave (recommended)
Firefox with uBlock Origin
Secondary Browser
Sensitive activities only

Use exclusively for banking, medical searches, legal matters, or anything you want completely isolated from your everyday browsing history.

DuckDuckGo Browser (recommended)
Firefox (separate profile)
Why does this matter?

When you use a single browser for everything, tracking companies build a detailed profile linking your shopping habits, news interests, social media activity, and even your medical searches together. By using a separate browser for sensitive activities — one you never use for anything else — you break that link. The secondary browser has no cookies, no history, and no cross-site tracking data connecting it to your everyday identity.

Browser Recommendations

An honest assessment of the major browsers, ranked by privacy and security.

Brave

Excellent

Best all-round privacy browser

PrimaryOpen Source

Brave is built on Chromium (the same engine as Chrome) but strips out all of Google's tracking and replaces it with strong privacy defaults. It blocks third-party ads and trackers on every page, randomises your browser fingerprint to make you harder to track, and requires no configuration to be significantly more private than Chrome or Edge. It is the top recommendation for most users as a primary everyday browser.

Pros
  • Blocks ads and trackers by default — no extensions needed
  • Fingerprint randomisation built in (changes canvas, audio, font hashes)
  • Chromium-based so compatible with all websites
  • Built-in Tor private windows for extra anonymity
  • No telemetry sent to Brave by default
  • Brave Search available as a private default search engine
Cons
  • Owned by a for-profit company (Brave Software Inc.)
  • Optional 'Brave Rewards' ad system can feel intrusive if enabled
  • Some advanced Chromium telemetry still present in the base engine

Firefox

Excellent

Best for customisation and trust

PrimaryOpen Source

Firefox is the most trusted open-source browser for privacy-conscious users. Backed by the non-profit Mozilla Foundation, it has a long history of standing up for user rights. Out of the box it blocks many trackers, but it benefits significantly from adding uBlock Origin and enabling Strict Enhanced Tracking Protection in settings. Firefox is the browser most recommended by security researchers for users who want control over their privacy.

Pros
  • Fully open source and backed by the non-profit Mozilla Foundation
  • Excellent extension ecosystem including uBlock Origin
  • Enhanced Tracking Protection blocks fingerprinters by default
  • Highly customisable privacy settings
  • Strong track record of resisting government data requests
  • Recommended by EFF, Privacy Guides, and NCSC
Cons
  • Fingerprint protection weaker than Brave out of the box
  • Requires extensions and configuration to reach Brave's default level
  • Mozilla has faced criticism for some data partnerships

DuckDuckGo Browser

Good

Best secondary browser for sensitive sessions

Secondary

DuckDuckGo's browser is an excellent choice as a secondary browser for sensitive activities — banking, medical searches, or anything you want completely isolated from your everyday browsing. The standout feature is the 'Fire Button': one tap instantly burns all your tabs, history, cookies, and cached data. This makes it ideal for sessions where you want zero trace left behind. It is simpler than Brave or Firefox but requires no configuration to be private.

Pros
  • Fire Button instantly wipes all tabs, history, and cookies
  • Blocks trackers and forces HTTPS on every site
  • Email Protection hides your real email address
  • Simple, clean interface — easy for non-technical users
  • Duck.ai built in for private AI chat
  • App Tracking Protection on Android blocks trackers in other apps
Cons
  • Fewer advanced settings than Brave or Firefox
  • Windows and Mac versions are relatively new
  • Less extension support than Chromium or Firefox browsers

Tor Browser

Excellent

Maximum anonymity for high-risk activities

SpecialistOpen Source

The Tor Browser is the gold standard for anonymity online. It routes your connection through three separate encrypted relays run by volunteers worldwide, making it extremely difficult for anyone — including your ISP, government, or the websites you visit — to identify you. All Tor users share the same browser fingerprint, meaning you blend into a crowd. It is recommended for investigative journalists, activists, or anyone who needs genuine anonymity. It is not designed for everyday use due to its slower speeds.

Pros
  • Routes traffic through 3 encrypted relays — extremely difficult to trace
  • All users share the same fingerprint — near-zero uniqueness
  • No browsing history stored
  • Based on Firefox with maximum privacy settings applied
  • Free and open source, maintained by the Tor Project
Cons
  • Significantly slower than regular browsers
  • Some websites block Tor exit nodes
  • Not suitable for everyday browsing or streaming
  • Requires understanding of how Tor works to use safely

Google Chrome

Caution

Popular but privacy-unfriendly

Avoid

Chrome is technically secure against malware and exploits, but it is the least privacy-friendly of the major browsers. Google's business model is built on advertising, and Chrome is a significant data collection tool. If you must use Chrome, disable sync, install uBlock Origin, and do not sign in to your Google account. For anything sensitive, switch to Brave, Firefox, or DuckDuckGo instead.

Pros
  • Excellent compatibility with all websites
  • Strong security updates and sandbox protection
  • Large extension library
Cons
  • Google collects extensive browsing data by default
  • Sync sends your history, passwords, and bookmarks to Google servers
  • Highly unique browser fingerprint — easy to track across sites
  • Not open source — you cannot verify what data is collected
  • Privacy Sandbox still allows interest-based ad targeting

Microsoft Edge

Caution

Better than Chrome, but still Microsoft

Avoid

Edge is a significant improvement over Internet Explorer and is better than Chrome for privacy out of the box, but it still sends telemetry and browsing data to Microsoft. If you are on Windows and do not want to install a third-party browser, enabling Edge's Strict tracking prevention is a reasonable baseline. For genuine privacy, Brave or Firefox are better choices.

Pros
  • Good built-in tracking prevention (Balanced mode)
  • Chromium-based so compatible with most websites
  • Built-in PDF reader and collections
Cons
  • Microsoft collects telemetry and browsing data
  • Bing integration and Copilot send queries to Microsoft
  • Frequent prompts to use Microsoft services
  • Not open source

How to Harden Your Browser

Even a privacy-focused browser can be made significantly more secure with a few configuration changes.

Mobile Browser Recommendations

Mobile browsing carries the same privacy risks as desktop — and often more, since your phone also knows your location.

iOS (iPhone)

  • Brave for iOS — best all-round option, blocks ads and trackers
  • DuckDuckGo for iOS — ideal secondary browser, Fire Button wipes everything
  • Firefox for iOS — good with uBlock Origin installed
  • Safari — reasonable privacy on iOS but tied to Apple ecosystem; avoid for sensitive browsing

Android

  • Brave for Android — top pick, full desktop-level privacy features
  • DuckDuckGo for Android — includes App Tracking Protection that blocks trackers in all your other apps
  • Firefox for Android — supports uBlock Origin, excellent privacy
  • Chrome for Android — avoid; sends data to Google by default
