org.mozilla.firefoxpackage. - Gentoo GNU/Linux supports stable and ESR builds via both binary and source compilation.
Other platforms have unfortunately proven difficult to support, though progress is being made. Contributions are always welcome and appreciated.
Note
Important
Android users are recommended to install IronFox (Recommended), which uses Phoenix for its configs. Android users can also manually install Phoenix for any Firefox-based browser on Android via directions.
# You can use `paru` instead of `yay` with the same options.
# Pacman:
yay -S phoenix-arch
# Pacman (System Flatpak):
yay -S phoenix-flatpakBefore installing Phoenix, you'll first need to add celenity's OBS repo:
Note
You may see a warning, such as the following, when updating your apt cache.
Warning: https://download.opensuse.org/repositories/home:/celenity/Debian_Unstable/InRelease: Policy will reject signature within a year, see --audit for detailsThis is because apt will not support V3 GPG keys after 2026-02-01, and
currently the OBS uses a V3 GPG key. For now, there shouldn't be any issues.

- Add the Phoenix repository to your flake inputs.
- Add
phoenixas one of the arguments to your output function. - Add the Phoenix NixOS Module to your configuration.
{
inputs = {
# Note that this assumes you have a flake-input called nixpkgs,
# which is often the case. If you've named it something else,
# you'll need to change the `nixpkgs` below.
phoenix = {
url = "git+https://gitlab.com/celenityy/Phoenix?ref=pages";
inputs.nixpkgs.follows = "nixpkgs";
};
};
# Add the `phoenix` argument to your output function, as below:
outputs = {nixpkgs, phoenix, ...}: {
# The configuration here is an example; it will look slightly different
# based on your machine name and architecture.
nixosConfigurations.your-box = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
modules = [
# This is the important part -- add this line to your module list!
phoenix.nixosModules.default
];
};
};
}Alternatively, the Phoenix package, overlay, and NixOS module can be used
directly in both flake and non-flake contexts. Simply pin the Phoenix source
repository using your tool of choice (e.g. niv, npins, flakes) and then include
nix/package.nix, nix/overlay.nix, or nix/module.nix as desired.
Caution
This is NOT recommended for most users.
By default, Phoenix is installed and updated via your operating system's package manager. This allows for fast, easy updates & fixes as needed, right with the rest of your system!
However, if this is not desirable for you and your situation, or you would simply like to use Phoenix on an unsupported operating system, you can manually install Phoenix with the following steps:
1: Download the archive for your desired Phoenix release:
This can be found at the link below (replacing {PHOENIX_VERSION}
with the version of Phoenix you'd like to download).
For reference, the latest version of Phoenix can always be
found at the top of the Releases page.
You can navigate to the link and download the archive directly from your web browser, or you can run the following command in your terminal:
https://releases.celenity.dev/phoenix/releases/{PHOENIX_VERSION}/linux/phoenix-{PHOENIX_VERSION}-linux.tar.xz
curl --disable --no-netrc --clobber --create-dirs --delegation none --disallow-username-in-url --doh-cert-status --fail --fail-early --junk-session-cookies --no-basic --no-ca-native --no-digest --no-doh-insecure --no-http0.9 --no-insecure --no-negotiate --no-ntlm --no-proxy-basic --no-proxy-ca-native --no-proxy-digest --no-proxy-insecure --no-proxy-ssl-auto-client-cert --no-sessionid --no-ssl-auto-client-cert --no-ssl-no-revoke --no-ssl-revoke-best-effort --no-xattr --parallel --post301 --post302 --post303 --progress-meter --proto -all,https --proto-default https --proto-redir -all,https --referer '' --remove-on-error --retry 5 --retry-all-errors --retry-connrefused --show-error --tlsv1.2 --trace-time --user-agent '' --verbose --remote-name --location https://releases.celenity.dev/phoenix/releases/{PHOENIX_VERSION}/linux/phoenix-{PHOENIX_VERSION}-linux.tar.xz2: Extract your downloaded archive:
First, create the directory where you'd like to extract Phoenix:
cd ~/Downloads # or where you downloaded the archive
mkdir -p phoenix && tar -xvf phoenix-{PHOENIX_VERSION}-linux.tar.xz -C phoenix3: If it does not already exist, you will want to
create a folder named firefox located in your system's etc directory.
This will work regardless of your distribution - even Snaps are supported.
sudo mkdir -p /etc/firefox && sudo chmod 655 /etc/firefox4: Copy phoenix.cfg to the /etc/firefox directory you just created.
You can either drag and drop it manually, or run the following command:
NOTE: If you have previously installed phoenix.cfg to a different location
(such as Firefox's installation directory),
please REMOVE it to ensure any conflicts are avoided.
sudo cp phoenix/phoenix.cfg /etc/firefox/phoenix.cfg5: If it does not already exist, inside the /etc/firefox directory,
create a new folder named defaults, and inside this new defaults folder,
create another folder titled pref. This will work
regardless of your distribution - even Snaps are supported.
sudo mkdir -p /etc/firefox/defaults/pref && sudo chmod 655 /etc/firefox/defaults/pref6: Copy phoenix.js to the
pref folder that you just created. You can run the following command:
NOTE: If you have a phoenix-desktop.js in this directory,
please REMOVE it to ensure any conflicts are avoided.
sudo cp phoenix/defaults/pref/phoenix.js /etc/firefox/defaults/pref/phoenix.js7: Non-Flatpak GNU/Linux users should instead create a policies folder
inside of the firefox folder located in /etc. This will work regardless
of your distribution, and even for Snaps.
sudo mkdir -p /etc/firefox/policies && sudo chmod 655 /etc/firefox/policies8: Finally, copy policies.json to your
/etc/firefox/policies folder you just created.
sudo cp phoenix/policies/policies.json /etc/firefox/policies/policies.json1: Download the archive for your desired Phoenix release:
This can be found at the link below (replacing {PHOENIX_VERSION} with the version of Phoenix you'd like to download). For reference, the latest version of Phoenix can always be found at the top of the Releases page.
https://releases.celenity.dev/phoenix/releases/{PHOENIX_VERSION}/osx/phoenix-{PHOENIX_VERSION}-osx.tar.xz
You can navigate to the link above and download the archive directly from your web browser, or you can run the following command in your terminal:

First, create the directory where you'd like to extract Phoenix:
mkdir -p phoenixNow, extract the downloaded archive:
(Replacing {PHOENIX_VERSION} with the version of Phoenix you'd like to download, and /path/to with the path to your downloaded archive)
tar xJf /path/to/phoenix-{PHOENIX_VERSION}-osx.tar.xz -C phoenix3: Locate your Firefox installation directory. This will vary depending on
your platform. An easy way to find it is by navigating to about:support and
checking the directory next to Application Binary.
For example: If I see /Users/${USER}/Applications/Firefox.app/Contents/MacOS/firefox listed next to Application Binary,
my installation directory would be: /Users/${USER}/Applications/Firefox.app.
Caution
Your directory will probably be different, and you should replace this directory on the following steps with your actual installation directory.
4: Copy macos/phoenix.cfg to the Resources folder within your installation directory.
You can either drag and drop it manually, or run the following command:
assuming /Users/${USER}/Applications/Firefox.app is your installation directory
sudo cp phoenix/macos/phoenix.cfg /Users/${USER}/Applications/Firefox.app/Resources/phoenix.cfg5: If it does not already exist, inside the Resources directory, create a new folder named defaults,
and inside this new defaults folder, create another folder titled pref.
You can do this manually through your file explorer, or you can run the following command:
assuming /Users/${USER}/Applications/Firefox.app is your installation directory
sudo mkdir -p /Users/${USER}/Applications/Firefox.app/Resources/defaults/prefYou'll also want to ensure that the folder you created has proper permissions:
sudo chmod 744 /Users/${USER}/Applications/Firefox.app/Resources/defaults/pref6: Copy defaults/pref/phoenix.js to the
pref folder that you just created. You can run the following command:
Assuming your installation directory is /Users/${USER}/Applications/Firefox.app
sudo cp phoenix/defaults/pref/phoenix.js /Users/${USER}/Applications/Firefox.app/Resources/defaults/pref/phoenix.js7: Finally, copy macos/org.mozilla.firefox.plist to
/Library/Preferences, and reboot your device once finished:
sudo cp phoenix/macos/org.mozilla.firefox.plist /Library/Preferences/org.mozilla.firefox.plist1: Download the archive for your desired Phoenix release:
This can be found at the link below (replacing {PHOENIX_VERSION} with the version of Phoenix you'd like to download). For reference, the latest version of Phoenix can always be found at the top of the Releases page.
https://releases.celenity.dev/phoenix/releases/{PHOENIX_VERSION}/windows/phoenix-{PHOENIX_VERSION}-windows.zip
You can navigate to the link above and download the archive directly from your web browser, or you can run the following command in your terminal:
Invoke-WebRequest -UserAgent '' -Uri 'https://releases.celenity.dev/phoenix/releases/{PHOENIX_VERSION}/windows/phoenix-{PHOENIX_VERSION}-windows.zip' -OutFile 'phoenix-{PHOENIX_VERSION}-windows.zip'2: Extract your downloaded archive:
First, create the directory where you'd like to extract Phoenix:
New-Item -ItemType 'Directory' -Name 'phoenix'Now, extract the downloaded archive:
(Replacing {PHOENIX_VERSION} with the version of Phoenix you'd like to download, and \Path\To with the path to your downloaded archive)
Expand-Archive -Path '\Path\To\phoenix-{PHOENIX_VERSION}-windows.zip' -DestinationPath 'phoenix'4: Locate your Firefox installation directory. This will vary depending on
your platform. An easy way to find it is by navigating to about:support and
checking the directory next to Application Binary.
Caution
Your directory will probably be different, and you should replace this directory on the following steps with your actual installation directory.
5: Copy phoenix.cfg to the root of your installation directory. You
can either drag and drop it manually, or run the following command:
Copy-Item -Path 'phoenix\phoenix.cfg' -Destination 'C:\Program Files\Mozilla Firefox\'6: If it does not already exist,
in the root of your installation directory, create a folder named
defaults, and inside this new defaults folder, create another folder titled
pref. You can do this manually through your file explorer, or you can run the
following command:
New-Item -Path 'C:\Program Files\Mozilla Firefox\' -ItemType 'Directory' -Name 'defaults\pref'7: Copy defaults\pref\phoenix.js to the
pref folder that you just created. You can run the following command:
Copy-Item -Path 'phoenix\defaults\pref\phoenix.js' -Destination 'C:\Program Files\Mozilla Firefox\defaults\pref\'8: In the root of your installation directory, create a
folder named distribution. You can do this manually through your file
explorer, or you can run the following command:
New-Item -Path 'C:\Program Files\Mozilla Firefox\' -ItemType 'Directory' -Name 'distribution'9: Finally, copy distribution\policies.json to the
distribution folder that you just created. You can run the following command:
Copy-Item -Path 'phoenix\distribution\policies.json' -Destination 'C:\Program Files\Mozilla Firefox\distribution\'Congratulations, you're done! Enjoy Phoenix, and be sure to keep up with updates!
