What is this?

This Python library wraps around Playwright's API to help automatically generate & inject unique device characteristics (OS, CPU info, navigator, fonts, headers, screen dimensions, viewport size, WebGL, addons, etc.) into Camoufox.

It uses fpgen under the hood to generate fingerprints that mimic the statistical distribution of device characteristics in real-world traffic.

In addition, it will also calculate your target geolocation, timezone, and locale to avoid proxy protection (see demo).

Installation

First, install the camoufox package:

pip install -U camoufox[geoip]

The geoip parameter is optional, but heavily recommended if you are using proxies. It will download an extra dataset to determine the user's longitude, latitude, timezone, country, & locale.

Next, download the Camoufox browser:

camoufox fetch

fetch also installs fpgen's model, pinned by sha256, into fpgen's package directory. Otherwise the first generated fingerprint installs it. Run fetch as that directory's owner if the browser will run as another user, e.g. while building a Docker image.

To uninstall, run camoufox remove.

Installing multiple Camoufox versions & from other repos

UI Manager

Manage installed browsers, active version, IP geolocation databases, and package info. Basically a Qt front end for the Python CLI tool.

More updates on it will be coming soon.

To use the gui, install Camoufox with the [gui] extra:

pip install 'camoufox[gui]'

To launch:

camoufox gui

Synced 26 versions from 2 repos.

Which browser build is used

Each camoufox release is paired with the one browser build it was built and tested with. By default, camoufox fetch installs exactly that build and every launch uses it. That holds even when other builds are installed, and even when the paired build is a prerelease (a prerelease of this package pairs with a prerelease browser). Upgrading the package therefore never runs a browser it was not tested with. Run camoufox fetch after upgrading to install the new pairing.

Choosing a channel or a build with camoufox set overrides the pairing. The choice is kept, and a launch warns that the build differs from the paired one. camoufox set --release goes back to the paired build.

A development checkout (installed from the repository, not from PyPI) is paired with nothing and follows its channel, official/stable by default.

set

Choose a version channel or pin a specific version, overriding the paired build. Can also be called with a specifier to activate directly.

Interactive selector:

> camoufox set

You can also pass a specifier to pin a specific version or choose a channel to follow directly. Following official/stable pulls the latest stable version from the official repo on camoufox fetch:

> camoufox set official/stable

Follow latest prerelease version from the official repo, if applicable:

> camoufox set official/prerelease

Pin a specific version:

> camoufox set official/stable/134.0.2-beta.20

Go back to the build this release is paired with:

> camoufox set --release

active

Prints the current active version string:

> camoufox active  # A released package uses its paired build by default
official/prerelease/156.0.1-beta.33 (1a2b3c4d) (paired with this release)

> camoufox set coryking/stable/142.0.1-fork.26
Pinned: coryking/stable/142.0.1-fork.26
Run 'camoufox fetch' to install.

> camoufox active  # A specific version is pinned
coryking/stable/142.0.1-fork.26 (not installed)

fetch

Install the browser build this release is paired with, or, after camoufox set, the latest version from the chosen channel. This will also automatically sync repository assets.

> camoufox fetch  # Install the paired build (or the latest in the chosen channel)

To download the latest from a different channel, or pin a version:

> camoufox set coryking/stable
> camoufox fetch  # Will download the latest release from CoryKing's repo for now on

Or pass in the identifier to download directly without activating it:

> camoufox fetch official/stable/135.0-beta.25   # Install a specific version

list

List installed or all available Camoufox versions as a tree.

> camoufox list          # show installed versions
> camoufox list all      # show all available versions from synced repos
> camoufox list --path   # show full install paths

remove

By default, removes the entire camoufox data directory.

> camoufox remove
> camoufox remove -y  # skip confirmation prompt

Remove a specific version:

> camoufox remove official/stable/134.0.2-beta.20

Interactively select a version to remove:

> camoufox remove --select

version

Display the Python package version, active browser version, channel, and update status.
