IronFox is a fork of [Divested Computing Group](https://divested.dev/)'s [Mull Browser](https://divestos.org/pages/our_apps#mull), based on [Mozilla Firefox](https://www.mozilla.org/firefox/). **Our goal is to continue the legacy of Mull by providing a free and open source, privacy and security-oriented web browser for daily use.**

> [!IMPORTANT]
>**⚠️ All users are HIGHLY recommended to take a look at our [documentation](./docs/README.md), ESPECIALLY the [Limitations](./docs/Limitations.md) and [Frequently Asked Questions](./docs/FAQ.md) pages!**

> While IronFox's home is [GitLab](https://gitlab.com/ironfox-oss/IronFox), this repo is also mirrored to both [Codeberg](https://codeberg.org/ironfox-oss/IronFox) & [GitHub](https://github.com/ironfox-oss/IronFox).

## App Installation

Currently, you can install IronFox from [Accrescent](https://accrescent.app/app/org.ironfoxoss.ironfox), from your preferred F-Droid client via our [F-Droid repository](fdroidrepos://fdroid.ironfoxoss.org/fdroid/repo?fingerprint=C5E291B5A571F9C8CD9A9799C2C94E02EC9703948893F2CA756D67B94204F904), with [Obtainium](obtainium://app/%7B%22id%22%3A%22org.ironfoxoss.ironfox%22%2C%22url%22%3A%22https%3A%2F%2Fgitlab.com%2Fironfox-oss%2Fironfox%22%2C%22author%22%3A%22ironfox-oss%22%2C%22name%22%3A%22ironfox%22%2C%22preferredApkIndex%22%3A0%2C%22additionalSettings%22%3A%22%7B%5C%22fallbackToOlderReleases%5C%22%3Atrue%2C%5C%22trackOnly%5C%22%3Afalse%2C%5C%22versionExtractionRegEx%5C%22%3A%5C%22%5C%22%2C%5C%22matchGroupToUse%5C%22%3A%5C%22%5C%22%2C%5C%22versionDetection%5C%22%3Atrue%2C%5C%22releaseDateAsVersion%5C%22%3Afalse%2C%5C%22useVersionCodeAsOSVersion%5C%22%3Afalse%2C%5C%22apkFilterRegEx%5C%22%3A%5C%22%5C%22%2C%5C%22invertAPKFilter%5C%22%3Afalse%2C%5C%22autoApkFilterByArch%5C%22%3Atrue%2C%5C%22appName%5C%22%3A%5C%22IronFox%5C%22%2C%5C%22shizukuPretendToBeGooglePlay%5C%22%3Afalse%2C%5C%22allowInsecure%5C%22%3Afalse%2C%5C%22exemptFromBackgroundUpdates%5C%22%3Afalse%2C%5C%22skipUpdateNotifications%5C%22%3Afalse%2C%5C%22about%5C%22%3A%5C%22A%20privacy%20and%20security-oriented%20Firefox-based%20browser%20for%20Android.%5C%22%2C%5C%22refreshBeforeDownload%5C%22%3Afalse%7D%22%2C%22overrideSource%22%3A%22GitLab%22%7D), or directly from our [GitLab releases](https://gitlab.com/ironfox-oss/IronFox/-/releases).

Regardless of your installation method, we recommend verifying Ironfox's package ID and the checksum of its signing certificate. You can simplify this process using [AppVerifier](https://github.com/soupslurpr/AppVerifier), which also has easy integration with Obtainium. **See [App Verification](#app-verification) below for IronFox's Package ID & SHA-256 of the signing certificate.**

If you are using F-Droid, we recommend [F-Droid Basic](https://f-droid.org/packages/org.fdroid.basic/) as your client of choice. Due to its reduced feature set, F-Droid Basic has less attack surface; meaning it is more secure than the standard client.

It should be noted that our F-Droid repo is hosted using Cloudflare's R2 Storage _(under the EU jurisdiction)_. While not perfect, Cloudflare does have a [strong privacy track record](https://discuss.privacyguides.net/t/quad9-or-cloudflare/15744/9), and due to their high reliabity and performance, we feel this is the best option for most users.

That being said, if you'd rather avoid Cloudflare, we also host a mirror of the F-Droid repo on [Codeberg](https://codeberg.org/ironfox-oss/fdroid), though it comes at the cost of lower reliability & performance. You can add the following link to your F-Droid client:

```sh
https://codeberg.org/ironfox-oss/fdroid/raw/branch/main/fdroid/repo
```

Once added, within the repository's settings on F-Droid, you can disable the other mirrors & leave Codeberg as the only selected option.

We also mirror the F-Droid repo on GitLab [here](https://gitlab.com/ironfox-oss/fdroid). You can add the following link to your F-Droid client if desired:

```sh
https://gitlab.com/ironfox-oss/fdroid/-/raw/main/fdroid/repo
```

## App Verification

**Package ID**: `org.ironfoxoss.ironfox`

**Package ID** *(Nightly)*: `org.ironfoxoss.ironfox.nightly`

**SHA-256 Hash of Signing Certificate**:

```sh
C5:E2:91:B5:A5:71:F9:C8:CD:9A:97:99:C2:C9:4E:02:EC:97:03:94:88:93:F2:CA:75:6D:67:B9:42:04:F9:04
```

## Building

IronFox makes it easier (and faster) to build the project locally.
For example, prebuilt versions of wasi-sdk sysroot and llvm-project are used instead of building them locally. ~~F-Droid builds still build those from source.~~

**It is recommended to use the Docker image for building IronFox.**

### Build with Docker

Pull the docker image with :

```sh
docker pull registry.gitlab.com/ironfox-oss/ironfox:latest
```

You can also use the `main` tag to pull the image which was used to
build the latest IronFox release. Or you can use exact version names
to pull images for those versions.

For example :

```
docker pull registry.gitlab.com/ironfox-oss/ironfox:v135-0
```

Then, you need to [set up the source files](#get--patch-sources).

### Build without Docker

**NOTE**: Currently, builds on the latest versions of **`Fedora`**, **`macOS`**, and **`Ubuntu`** systems are supported. YMMV for other operating systems/environments.

**NOTE**: **`macOS`** users must install [Homebrew](https://brew.sh/) *(if is not already installed)* before following the steps below.

First, if you haven't already installed it, you'll want to install `git` for your platform of choice:

**`Fedora`**:

```sh
sudo dnf install git
```

**`macOS`**:

```sh
brew install git
```

**`Ubuntu`**:

```sh
sudo apt install git
```

After you've successfully installed `git`, the first thing you'll need to do is clone IronFox's source repository:

*(`--depth=1` is specified below to reduce the size of the cloned repository, it can be removed if preferred)*

```sh
git clone --depth=1 git@gitlab.com:ironfox-oss/IronFox.git IronFox
```

You should now navigate to the root of IronFox's source directory, and run the `bootstrap` script:

*(The `bootstrap` script will set-up and install dependencies required to build IronFox on your system)*

```sh
cd IronFox
./scripts/bootstrap.sh
```

#### Get sources

Still from the root of IronFox's source directory, you should now run the `get_sources` script to download the external sources required for building IronFox:

**NOTE**: If you need to fetch sources for a different version of a dependency than the version IronFox is currently using, you'll need to modify `scripts/versions.sh` **BEFORE** running the `get_sources` script.

_This may take some time depending on your network speed..._

```sh
./scripts/get_sources.sh
```

#### Preparing sources

You now need to patch/prepare your newly downloaded sources with the `prebuild` script:

_This must be run once after getting your sources._

```sh
./scripts/prebuild.sh <build-variant>
```

Where `<build-variant>` specifies the variant to build, and is **one** of the following:

- `arm` - 32-bit ARM (`armeabi-v7a`)
- `arm64` - 64-bit ARM (`arm64-v8a`)
- `x86_64` - 64-bit x86
- `bundle` - Android App Bundle (AAB) with all supported ABIs.

> [!IMPORTANT]
> If you want to build the `bundle` variant locally, you need to build the ABI-specific
> variants first, get the generated AAR file for GeckoView and then configure
> `MOZ_ANDROID_FAT_AAR*` environment variables with the path to the generate AAR files.
>
> See [task kinds](https://firefox-source-docs.mozilla.org/taskcluster/kinds.html#build-fat-aar) and [ci-build.sh](./scripts/ci-build.sh) for more details.

#### Build

Finally, you can start the build process with:

```sh
./scripts/build.sh apk
```

**NOTE**: If you'd like to build a **bundle**, you should instead use:

```sh
./scripts/build.sh bundle
```
