European Alternatives to Firefox

Firefox is an open-source browser from Mozilla (US non-profit). While more privacy-respecting than Chrome, it sends telemetry to Mozilla and comes with various data collection features enabled by default.

Why Switch from Firefox?

  • Default telemetry reports browsing behaviour to Mozilla (US)
  • Mozilla's ad partnership raised questions about privacy commitments
  • US-based non-profit subject to US data laws
  • Default search engine partnerships involve data sharing

Frequently Asked Questions

What are the best European alternatives to Firefox?

Mullvad Browser is co-developed by Mullvad (Sweden) and the Tor Project — designed to standardise browser fingerprints and block all tracking. LibreWolf is a hardened Firefox fork with all telemetry removed. Vivaldi (Norway) is a Chromium-based option with strong privacy features.

What makes Mullvad Browser different from Firefox?

Mullvad Browser comes with uBlock Origin pre-installed, blocks all telemetry, standardises your browser fingerprint to make you indistinguishable from other Mullvad users, and disables all features that phone home to Mozilla.

Is LibreWolf compatible with Firefox extensions?

Yes — LibreWolf is fully compatible with all Firefox Add-ons from addons.mozilla.org. It's essentially Firefox with all privacy-invasive features removed and additional hardening applied.

Do European browsers support all websites?

Yes — Vivaldi is Chromium-based, giving near-perfect site compatibility. LibreWolf and Mullvad Browser are Firefox-based and compatible with the vast majority of websites.
