Fedora

If you're running Fedora 30, instead, you can install the dependencies with

sudo dnf install git python bzip2 tar pkgconfig atk-devel alsa-lib-devel bison binutils brlapi-devel bluez-libs-devel bzip2-devel cairo-devel cups-devel dbus-devel dbus-glib-devel expat-devel fontconfig-devel freetype-devel gcc-c++ glib2-devel glibc gperf gtk3-devel java-1.*.0-openjdk-devel libatomic libcap-devel libffi-devel libgcc libgnome-keyring-devel libjpeg-devel libstdc++ libX11-devel libXScrnSaver-devel libXtst-devel libxkbcommon-x11-devel ncurses-compat-libs nspr-devel nss-devel pam-devel pango-devel pciutils-devel pulseaudio-libs-devel zlib httpd mod_ssl php php-cli python-psutil wdiff xorg-x11-server-Xvfb clang vim cmake pkg-config krb5-devel re2c subversion curl nodejs libuuid-devel ninja-build libva-devel ccache xz patch diffutils findutils coreutils @development-tools elfutils rpm-devel rpm rpm-build fakeroot 

NOTE: Fedora 31 and later is not supported because libgnome-keyring-devel has been deprecated for libsecret and Chromium yet doesnt support libsecret.

/!\ You must remove the build folder before running the build script again.

ungoogled-chromium

A lightweight approach to removing Google web service dependency

Help is welcome! See the docs/contributing.md document for more information.

Objectives

In descending order of significance (i.e. most important objective first):

1. ungoogled-chromium is Google Chromium, sans dependency on Google web services.
2. ungoogled-chromium retains the default Chromium experience as closely as possible. Unlike other Chromium forks that have their own visions of a web browser, ungoogled-chromium is essentially a drop-in replacement for Chromium.
3. ungoogled-chromium features tweaks to enhance privacy, control, and transparency. However, almost all of these features must be manually activated or enabled. For more details, see Feature Overview.

In scenarios where the objectives conflict, the objective of higher significance should take precedence.

Motivation and Philosophy

Without signing in to a Google Account, Chromium does pretty well in terms of security and privacy. However, Chromium still has some dependency on Google web services and binaries. In addition, Google designed Chromium to be easy and intuitive for users, which means they compromise on transparency and control of internal operations.

ungoogled-chromium addresses these issues in the following ways:

1. Remove all remaining background requests to any web services while building and running the browser
2. Remove all code specific to Google web services
3. Remove all uses of pre-made binaries from the source code, and replace them with user-provided alternatives when possible.
4. Disable features that inhibit control and transparency, and add or modify features that promote them (these changes will almost always require manual activation or enabling).

These features are implemented as configuration flags, patches, and custom scripts. For more details, consult the Design Documentation.

Feature Overview

This section overviews the features of ungoogled-chromium. For more detailed information, it is best to consult the source code.

Contents of this section:

• Key Features
• Enhancing Features
• Borrowed Features
• Supported Platforms and Distributions

Key Features

These are the core features introduced by ungoogled-chromium.

• Disable functionality specific to Google domains (e.g. Google Host Detector, Google URL Tracker, Google Cloud Messaging, Google Hotwording, etc.)
  • This includes disabling Safe Browsing. Consult the FAQ for the rationale.
• Block internal requests to Google at runtime. This feature is a fail-safe measure for the above, in case Google changes or introduces new components that our patches do not disable. This feature is implemented by replacing many Google web domains in the source code with non-existent alternatives ending in qjz9zk (known as domain substitution; see docs/design.md for details), then modifying Chromium to block its own requests with such domains. In other words, no connections are attempted to the qjz9zk domain.
• Strip binaries from the source code (known as binary pruning; see docs/design.md for details)

Enhancing Features

These are the non-essential features introduced by ungoogled-chromium.

• Add many new command-line switches and chrome://flags entries to configure new features (which are disabled by default). See docs/flags.md for the exhaustive list.
• Add Suggestions URL text field in the search engine editor (chrome://settings/searchEngines) for customizing search engine suggestions.
• Add more URL schemes allowed to save page schemes.
• Add Omnibox search provider "No Search" to allow disabling of searching
• Add a custom cross-platform build configuration and packaging wrapper for Chromium. It currently supports many Linux distributions, macOS, and Windows. (See docs/design.md for details on the system.)
• Force all pop-ups into tabs
• Disable automatic formatting of URLs in Omnibox (e.g. stripping http://, hiding certain parameters)
• Disable intranet redirect detector (extraneous DNS requests)
  • This breaks captive portal detection, but captive portals still work.
• (Iridium Browser feature change) Prevent URLs with the trk: scheme from connecting to the Internet
  • Also prevents any URLs with the top-level domain qjz9zk (as used in domain substitution) from attempting a connection.
• (Windows-specific) Do not set the Zone Identifier on downloaded files

Borrowed Features

In addition to the features introduced by ungoogled-chromium, ungoogled-chromium selectively borrows many features from the following projects (in approximate order of significance):

• Inox patchset
• Bromite
• Debian
• Iridium Browser

Supported Platforms and Distributions

See docs/platforms.md for a list of supported platforms.

Other platforms are discussed and tracked in this repository's Issue Tracker. Learn more about using the Issue Tracker under the section Contributing, Reporting, Contacting.

Downloads

Download binaries from here

NOTE: These binaries are provided by anyone who are willing to build and submit them. Because these binaries are not necessarily reproducible, authenticity cannot be guaranteed; In other words, there is always a non-zero probability that these binaries may have been tampered with. In the unlikely event that this has happened to you, please report it in a new issue.

These binaries are known as contributor binaries.

Also, ungoogled-chromium is available in several software repositories:

• Android: Available via a custom F-Droid repo. See instructions in ungoogled-chromium-android
• Arch: Available in AUR as ungoogled-chromium
• Debian & Ubuntu: Available in OBS, find your distribution specific instructions in the Installing section
• Fedora & CentOS: Available in OBS, by following instructions in the downloads section. For Fedora also available in RPM Fusion as chromium-browser-privacy.
• Gentoo: Available in ::pf4public overlay as ungoogled-chromium ebuild
• macOS: Available in Homebrew as eloston-chromium. Just run brew fetch --cask eloston-chromium and brew install --cask eloston-chromium. Chromium will appear in your /Applications directory.

If your GNU/Linux distribution is not listed, there are distro-independent builds available via the following package managers:

• Flatpak: Available in the Flathub repo as com.github.Eloston.UngoogledChromium
• GNU Guix: Available as ungoogled-chromium
• NixOS/nixpkgs: Available as ungoogled-chromium

Source Code

This repository only contains the common code for all platforms; it does not contain all the configuration and scripts necessary to build ungoogled-chromium. Most users will want to use platform-specific repos, where all the remaining configuration and scripts are provided for specific platforms:

Find the repo for a specific platform here.

If you wish to include ungoogled-chromium code in your own build process, consider using the tags in this repo. These tags follow the format {chromium_version}-{revision} where

• chromium_version is the version of Chromium used in x.x.x.x format, and
• revision is a number indicating the version of ungoogled-chromium for the corresponding Chromium version.

Additionally, most platform-specific repos extend their tag scheme upon this one.
