Dove works by leveraging Thunderbird's [AutoConfig](https://enterprise.thunderbird.net/deploy/mcd-thunderbird-autoconfig) & [Enterprise Policies](https://github.com/thunderbird/policy-templates/tree/master/templates/central) functionality, and is installed on top of your standard, official Thunderbird installation. **This allows us to go above and beyond what a simple `user.js` file can offer, without the security risks of using a fork**. For example, forks often fall behind on Thunderbird updates, **which can leave users open to severe, detrimental vulnerabilities.** Dove's approach allows users to continue receiving immediate updates, directly from Mozilla.

Dove's approach also provides users with a seamless experience that is accessible and easy to use. Gone are the days of creating `override` files, manually keeping track of updates, & resetting old preferences. **Not only is Dove the most effective & comprehensive approach to configuring Thunderbird, it is also the most accessible & easiest to use.**

Dove's settings & changes to Thunderbird are carefully considered based on extensive research & studying of Thunderbird's inner workings. **For an incomplete, non-exhaustive list of Dove's features & enhancements, see [here](https://dove.celenity.dev/features).**

**Dove is designed to maintain compatibility with email providers and to avoid breakage as much as possible, while still substantially improving privacy & security compared to vanilla Thunderbird & most other email clients.**

**You should also see [here](https://dove.celenity.dev/compare) for a comparison between Dove, standard Thunderbird, thunderbird-user.js, & other projects of similar nature.**

**Dove also disables various anti-features & strives to put the user back in control of their email experience.** Additionally, Dove includes quality of life enhancements, performance improvements, and other 'goodies' where possible and where it doesn't compromise user privacy or security.

At the end of the day, above all else:

**Dove is designed from the ground up to always put the user first.**

 Before installing Dove, you'll first need to add [celenity's OBS repo](https://build.opensuse.org/project/show/home:celenity):

> [!NOTE]
> You may see a warning, such as the following, when updating your `apt` cache.
>
> ```sh
> Warning: https://download.opensuse.org/repositories/home:/celenity/Debian_12/InRelease: Policy will reject signature within a year, see --audit for details
> ```
>
> This 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.

 ```sh
 echo 'deb https://download.opensuse.org/repositories/home:/celenity/Debian_12/ /' | sudo tee /etc/apt/sources.list.d/home:celenity.list
 wget -O- https://download.opensuse.org/repositories/home:celenity/Debian_12/Release.key 2>/dev/null | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_celenity.gpg > /dev/null

NixOS is supported for [flake-based configurations](https://wiki.nixos.org/wiki/Flakes#Using_nix_flakes_with_NixOS):
1. Add Dove and Phoenix repositories to your flake inputs (Dove is based on Phoenix configs).
2. Add `dove` as one of the arguments to your output function.
3. Add the Dove NixOS Module to your configuration.
```nix
{
  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.
    dove = {
      url = "git+https://gitlab.com/celenityy/Dove.git";
      inputs.nixpkgs.follows = "nixpkgs";
	  inputs.phoenix.follows = "phoenix";
    };
	phoenix = {
      url = "git+https://gitlab.com/celenityy/Phoenix.git";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };
  # Add the `dove` argument to your output function, as below:
  outputs = {nixpkgs, dove, ...}: {
	# 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!
        dove.nixosModules.default
      ];
	};

# 📛Manual Installation

> [!CAUTION]
>**This is NOT recommended for most users.**

By default, Dove is installed & 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 & your situation, or you would simply like to use Dove on an unsupported operating system, you can manually install Dove with the following steps:

**1:** Download `dove.cfg` for your platform:

```

**3:** Download `policies.json` *(or `org.mozilla.thunderbird.plist` for macOS users)* for your platform:

- Linux: [`https://gitlab.com/celenityy/Dove/-/raw/pages/linux/policies/policies.json`](https://gitlab.com/celenityy/Dove/-/raw/pages/linux/policies/policies.json)

You can right click and select `Save page as` from your browser after navigating to the link for your platform's `policies.json` *(or `org.mozilla.thunderbird.plist` for macOS users)*, or you can run the following command in your terminal:

**Linux**:

```sh
curl --cert-status --doh-cert-status --no-insecure --no-proxy-insecure --no-sessionid --no-ssl --no-ssl-allow-beast --no-ssl-auto-client-cert --no-ssl-no-revoke --no-ssl-revoke-best-effort --proto -all,https --proto-default https --proto-redir -all,https --show-error -O -sSL https://gitlab.com/celenityy/Dove/-/raw/pages/linux/policies/policies.json
```

**macOS**:

```sh

```

**Windows**:

```sh
curl --cert-status --doh-cert-status --no-insecure --no-proxy-insecure --no-sessionid --no-ssl --no-ssl-allow-beast --no-ssl-auto-client-cert --no-ssl-no-revoke --no-ssl-revoke-best-effort --proto -all,https --proto-default https --proto-redir -all,https --show-error -O -sSL https://gitlab.com/celenityy/Dove/-/raw/pages/windows/distribution/policies.json
```

**4:** Locate your Thunderbird installation directory. This will vary depending on your platform, you can generally find it by navigating to `Help` (Located on top bar) -> `Troubleshooting information` & checking the directory next to `Application Binary`. For example, on Fedora Linux, I see `/usr/lib64/thunderbird/thunderbird` next to `Application Binary`. This means our installation directory is `/usr/lib64/thunderbird`.

> [!CAUTION]
>**Unless you're on Fedora Linux, your directory will probably be different, and you should replace this path on the following steps with your actual installation directory's path.**

**5:** Move `dove.cfg` to the **root** of your installation directory. You can either drag and drop it manually, or run the following command:

**Linux/macOS**, *assuming `/usr/lib64/thunderbird` is your installation directory*:

```sh
sudo cp dove.cfg /usr/lib64/thunderbird/dove.cfg
```

**Windows**:

```sh
cp dove.cfg C:\'Program Files'\'Mozilla Thunderbird'\dove.cfg
```

**6:** **For macOS, Windows, and Flatpak users**: 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 for your platform:

**Flatpak/macOS**, *assuming `/usr/lib64/thunderbird` is your installation directory*:

```sh
sudo mkdir -vp /usr/lib64/thunderbird/defaults/pref
```

**Windows**:

```sh
mkdir -vp C:\'Program Files'\'Mozilla Thunderbird'\defaults\pref
```

**For standard Linux users:** If it does not already exist, you will want to create a folder named `thunderbird` located in your system's `etc` directory. Inside this `thunderbird` folder, 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. You can also just run the command below:

```sh
sudo mkdir -vp /etc/thunderbird/defaults/pref
```

On macOS and GNU/Linux, you'll also want to ensure that the folder you created has proper permissions:

**Flatpak/macOS**, *assuming `/usr/lib64/thunderbird` is your installation directory*:

```sh
sudo chmod 744 /usr/lib64/thunderbird/defaults/pref
```

**For all non-Flatpak GNU/Linux users:**

```sh
sudo chmod 655 /etc/thunderbird/defaults/pref
```

**7:** Move `dove.js` to the `pref` folder that you just created. You can run the following command for your platform below:

**Linux/macOS**, *Assuming your installation directory is `/usr/lib64/thunderbird`*:

```sh
sudo cp dove.js /usr/lib64/thunderbird/defaults/pref/dove.js
```

**Windows**:

```sh
cp dove.js C:\'Program Files'\'Mozilla Thunderbird'\defaults\pref\dove.js
```

**For all non-Flatpak GNU/Linux users:**

```sh
sudo cp dove.js /etc/thunderbird/defaults/pref/dove.js
```

**8:** On Windows, 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:

```sh
mkdir -vp C:\'Program Files'\'Mozilla Thunderbird'\distribution
```

non-Flatpak GNU/Linux users should **instead** create a `policies` folder inside of the `thunderbird` folder located in `/etc`. This will work **regardless** of your distribution, and even for Snaps.

```sh
sudo mkdir -vp /etc/thunderbird/policies
```

For non-Flatpak GNU/Linux users, you'll also want to ensure that the folder you created has proper permissions:

```sh
sudo chmod 655 /etc/thunderbird/policies
```

**9:** Now, those on Windows should copy `policies.json` to the `distribution` folder that you just created. You can run the following command:

```sh
cp policies.json C:\'Program Files'\'Mozilla Thunderbird'\distribution\policies.json
```

macOS users should **instead** copy `org.mozilla.thunderbird.plist` to `/Library/Preferences`, and **reboot** their device once finished:

```sh
sudo cp org.mozilla.thunderbird.plist /Library/Preferences/org.mozilla.thunderbird.plist`
```

GNU/Linux users should **instead** copy `policies.json` to their `/etc/thunderbird/policies` folder they just created.

```sh
sudo cp policies.json /etc/thunderbird/policies/policies.json
```

**10**: Within your Dove `assets` directory, create a directory titled `autoconfig`, and within that directory, create a directory titled `v1.1`. Navigate into the `v1.1` directory.

**Linux** *(Non-Flatpak)*:

```sh
mkdir -vp /etc/thunderbird/dove/assets/autoconfig/v1.1
cd /etc/thunderbird/dove/assets/autoconfig/v1.1
```

**Linux** *(Flatpak)*:

```sh
mkdir -vp /var/lib/flatpak/app/org.mozilla.Thunderbird/current/active/files/etc/thunderbird/dove/assets/autoconfig/v1.1
cd /var/lib/flatpak/app/org.mozilla.Thunderbird/current/active/files/etc/thunderbird/dove/assets/autoconfig/v1.1
```

**macOS** *(Apple Silicon)*:

```sh
mkdir -vp /opt/homebrew/opt/dove/assets/autoconfig/v1.1
cd /opt/homebrew/opt/dove/assets/autoconfig/v1.1
```

**macOS** *(Intel)*:

```sh
mkdir -vp /usr/local/opt/dove-intel/assets/autoconfig/v1.1
cd /usr/local/opt/dove-intel/assets/autoconfig/v1.1
```

**Windows**:

```sh
mkdir -vp C:\dove\assets\autoconfig\v1.1
cd C:\dove\assets\autoconfig\v1.1
```

**11:** Download Mozilla's latest autoconfiguration files into the root of the `v1.1` directory. These [can be found here](https://autoconfig.thunderbird.net/v1.1/). The easiest way to download them is by installing **`wget`** *(if you haven't already)*, and running the following command in your Terminal:

```sh
wget -r -np -nH --cut-dirs=3 -R index.html -e robots=off https://autoconfig.thunderbird.net/v1.1/
```

**Alternatively**: At the cost of privacy and security, after installing Dove, you can set the value of `mailnews.auto_config_url` to `https://autoconfig.thunderbird.net/v1.1/` in your `about:config` *(Accessible by navigating to `Settings` -> `General` -> Scroll to the bottom -> `Config Editor...`)*. This is **NOT** recommended, as it will share your email provider with Mozilla, and is slower/less responsive.

Congratulations, you're done. Enjoy Dove, and be sure to keep up with updates!
