## What it is
Mullvad Browser is a privacy-focused desktop web browser developed jointly by Mullvad VPN and the Tor Project, essentially a Tor Browser designed to be used without the Tor Network. It minimizes tracking and browser fingerprinting by making all users appear alike, intended to be paired with a trustworthy VPN.

## Use cases
- browse the web without being tracked or fingerprinted
- use a Tor Browser-like browser without the Tor network
- reduce browser fingerprinting for anonymity
- pair a privacy browser with a VPN for mass surveillance resistance
- block third-party trackers and cookies
- make my browser look like everyone else's to websites

## When to choose
- you want Tor Browser's anti-fingerprinting protections without Tor's slow onion routing
- you already use a VPN and want a browser that doesn't leak identifying data
- you need a hardened, preconfigured privacy browser on Linux, macOS, or Windows

## When to avoid
- you need anonymity via onion routing itself - use Tor Browser instead
- you need mobile support - it is desktop-only
- you want to customize extensions freely, which can break the uniform fingerprint
