项目性质： Firefox官方代码的社区分支。它突破了Mozilla官方的支持截止日期，将Firefox的新功能、性能改进和安全补丁“移植”到了不再受官方支持的Windows平台上。

【火狐浏览器的编译方法】

Building

Bootstrap a copy of the Firefox source code

git clone https://github.com/mozilla-firefox/firefox.git

This repository contains patches for specific versions of Firefox, stored in directories named <DATE>.<commit_id>. Here, commit_id is the commit ID of Firefox, and DATE is purely for File Explorer.

cd firefox
git checkout <commit_id>
./mach bootstrap

Building Rust on Windows MSVC

To ensure that rustc always generates programs compatible with Windows 7, Rust needs to be patched. This repository contains files named Rust<rust_version>win7.diff for this purpose, where rust_version is the version of Rust used to build Firefox, as specified here. For detailed instructions on how to proceed, please refer to #75.

    Clone the source with git

    git clone https://github.com/rust-lang/rust.git
    cd rust
    git checkout <rust_version>

Apply patch

git apply --verbose --ignore-space-change Rust<rust_version>win7.diff

If you want to support Windows Vista, you also need to apply Rust<rust_version>vista.diff:

git apply --verbose --ignore-space-change Rust<rust_version>vista.diff

Build

python x.py build --target i686-pc-windows-msvc,x86_64-pc-windows-msvc
python x.py build library --target i686-pc-windows-msvc,x86_64-pc-windows-msvc

Compiling Cargo from Source

    Clone the source with git

    git clone https://github.com/rust-lang/cargo.git
    cd cargo

With cargo already installed by ./mach bootstrap, you can simply run:

cargo build --release

Apply patches

Navigate to the <DATE>.<commit_id> directory, modify the REPO_PATH variable in apply_patches.bat to the path of the Firefox source, and then double-click it to apply the patches.

Build Firefox

    Add our custom-built rustc.exe and cargo.exe to your PATH, delete or rename %USERPROFILE%\.rustup and %USERPROFILE%\.cargo, and remove any other instances of rustc.exe and cargo.exe from your PATH.
