Mullvad Browser
Sweden
A privacy-focused browser built with Tor Project that makes all users look the same to trackers.
European Alternative to:

A privacy browser built jointly by Mullvad VPN (Sweden) and the Tor Project. The idea is straightforward: take Tor Browser's hardened, anti-fingerprinting profile, but strip out the connection to the Tor network so you can use it with a regular VPN, or no VPN at all.
What you get
- A Firefox-based browser with strict anti-fingerprinting defaults
- All the usual Tor Browser hardening: no telemetry, no built-in account, no behavioural tracking
- Letterboxing, font and language fingerprint resistance, content-blocking by default
- Builds for Windows, macOS and Linux
- Free, with no signup, no account, nothing to register
Where it sits
Maintained as a collaboration between Mullvad and the Tor Project, with the Mullvad side based in Gothenburg, Sweden. The browser doesn't talk to Mullvad's VPN service in any special way; it's standalone, and you can pair it with any VPN or use it bare.
Honestly
A lot of websites that rely on fingerprinting for "security" (read: bot detection) will challenge you constantly. That's the price of the anti-fingerprinting work, and it's the same problem Tor Browser users have lived with for years. For day-to-day private browsing where you don't want to be uniquely identifiable, it's one of the strongest options that isn't full Tor.
