European web browsers are rarer than European search engines, but there are real options: Vivaldi and Opera from Norway, Mullvad Browser from Sweden, Ecosia Browser from Germany and community builds such as LibreWolf. Firefox is also listed as an open-source alternative that anyone can fork and self-build.
Privacy-focused browsers
Mullvad Browser is developed together with the Tor Project and aims to minimise tracking and fingerprints; it is open source, free of charge and runs on Linux, macOS and Windows.[1] LibreWolf is an independent, largely community-driven version of Firefox built from the latest Firefox stable source, with telemetry removed.[2] Firefox itself presents itself as an independent browser that blocks trackers.[3]
Feature-rich and everyday browsers
Vivaldi describes itself as an independent browser company based in Norway and Iceland.[4] It ships a built-in ad blocker, mail client, calendar, feed reader, tab stacks and page translation.[5] Opera was born in Oslo, which is still its home base.[6] Ecosia Browser funds tree planting and renewable energy.[7]
What to keep in mind
Most of these browsers are built on a Chromium or Firefox engine from outside Europe, so the benefit lies in the company, its data practices and its features rather than in a separate European engine. Check each product page for ownership and open-source status before you switch.
