The Truth About Browser Privacy: The Good, Bad & Dangerous

Technological concepts & privacy/security framing

• VPNs aren’t enough: VPNs can block your ISP from logging visited sites, hide your IP address from websites, and encrypt traffic—but they do not stop browser fingerprinting and do not prevent browsers from sharing data with big tech (Google, Microsoft, Samsung, Apple).
• Three “pillars” of privacy:
  1. a good privacy-focused browser (core topic of the video)
  2. VPN as one component
  3. good online habits (promised for a future video)

How the video evaluates browsers (scoring methodology)

To compare many browsers without extensions, the speaker builds an objective scoring system based on five criteria (each scored 0–5, total 0–25):

1. Telemetry / data collection: whether the browser sends browsing/device info back to the company.
2. Blocking tracking: whether the browser can block ads, social media trackers, and cookies without extra tweaking/extensions (e.g., Facebook “pixels”).
3. Anti-fingerprinting: how well websites can’t fingerprint your browser/device.
4. IP/DNS leak protection: hiding IP address and preventing DNS leaks (not as critical if using a VPN; mentions workarounds like using Tor/Brave on iOS via “Tor tabs”).
5. Open source & auditable: whether the code is open enough for independent review for backdoors/spying.

Interpretation guide used:

• 21–23: very solid
• 24–25: nearly perfect
• 10 or less: should be avoided if privacy matters

Desktop results: “best” and “worst” privacy browsers

Five most private (desktop)

• Tor (ranked #1, 25/25)
• Mullvad
• LibreWolf
• Brave
• Ungoogled Chromium (All scored 21+.)

Caveat noted:

• Tor can be slow due to multi-node routing and possible bandwidth limits.

Five worst (desktop) by score (≤10)

• Opera
• Safari
• Yandex
• Microsoft Edge
• Google Chrome

Context notes:

• Yandex is headquartered in Moscow.
• Opera is described as Chinese-owned/partially Chinese operated.

Free browser testing tool (and what the tests show)

The speaker recommends using a free tool:

• Cover Your Tracks (EFF): tests whether a browser blocks tracking ads/invisible trackers and how resistant it is to fingerprinting.

Mullvad test highlight

• Achieved a “privacy trifecta” on the tool:
  • blocked tracking ads
  • blocked invisible trackers
  • no unique fingerprint
• Only “lost” a point because it needs a VPN (though the speaker says they always use Mullvad VPN).

Fingerprinting “bits” explanation

• The video uses EFF-style data “bits” to explain uniqueness: more bits = easier for websites to uniquely profile/track you.

Desktop fingerprinting observations

• The speaker tested four browsers on coveryourtracks.eff.org:
  • Brave: 18 bits, described as partially randomly generated (less useful for tracking)
  • Safari and Chrome: 18 bits, described as real, making them easier to fingerprint and track
• The speaker admits using Chrome only for uploading/operating a YouTube account, not general browsing, due to its low privacy score.

Mobile results: best and worst privacy browsers

Android (top privacy in this video’s ranking)

• Tor (25) and Mullvad (24)—best results, but Android-only availability is emphasized.

iOS top privacy browsers (per criteria/scoring)

• Firefox Focus
• Brave
• DuckDuck Go

Mobile worst (≤10)

• Samsung Internet
• Opera
• Safari
• Microsoft Edge
• Google Chrome

The speaker stresses that most mobile users use Safari/Chrome/Samsung Internet (~95%), creating a privacy problem for the average user.

iPhone testing highlights

• Firefox Focus and Brave: “privacy trifecta”; both reported 18 bits, but with randomized data (non-unique fingerprints).
• DuckDuckGo: sends less identifying info (compared to having only part of a license plate number).
• Safari and Chrome: surprisingly include some randomized data to obscure fingerprinting, but still score low overall due to other criteria (telemetry/tracking, etc.).

Browser extensions: guidance and tradeoffs

• Extensions are described as a double-edged sword: useful for blocking trackers, but can also make your browser more identifiable (analogy: adding a distinctive bumper sticker).
• Recommended extension (for certain privacy browsers):
  • uBlock Origin (Raymond Hill)
    • Warning: ensure you install “uBlock Origin”, not lookalikes like “uBlock”.
  • Claimed capabilities: blocks ads, trackers, coin miners, and malicious scripts via constantly updated filters; open-source; supports stopping tracking tools like Meta pixels and Google Analytics.

Reviews/controls and “picking a browser”

The overall “tutorial” component is: use the scoring criteria + EFF testing tool to evaluate any browser and choose based on your tolerance for:

• telemetry risk
• tracker blocking effectiveness (without extra extensions)
• fingerprint resistance
• IP/DNS leak concerns (and whether you use a VPN)
• open-source/auditability

Sponsorship/extra notes (not core privacy content)

• The video includes sponsorship by Flexispot (standing desk/treadmill). Not directly related to browser privacy, aside from mentioning.
• Mentions a prior video about choosing a VPN and links it.
