Requirements

To build the docker image you need at least 2 GB disk space.

To run the container and building firefox you need at least additional 20 GB disk space.

• Open Container Runtime (i.e. containerd, mobby-engine)
• bash
• envsubst via gettext (Fedora)
• desktop-file-install via desktop-file-utils (Fedora)
• tar via tar (Fedora)

Usage

Prepare Build Environment

Build Container Image

Clone and build docker image:

git clone https://git.compilenix.org/CompileNix/firefox-build.git
cd firefox-build
DOCKER_BUILDKIT=0 docker build -t firefox-build:fedora .

Download Build Tools And Firefox Sources

Now you can prepare the build enviroment, by installing GIT cinnabar and downloading Firefox source using bootstrap.py.

When asked for Destination directory for clone, enter: mozilla-unified

mkdir -v dist mozilla-unified mozbuild; chmod -v 0777 dist mozilla-unified mozbuild
docker run -v $(pwd)/dist:/dist:z -v $(pwd)/mozbuild:/root/.mozbuild:z -v $(pwd)/mozilla-unified:/src/mozilla-unified:z -v $(pwd)/mozconfig:/src/mozconfig:z -v $(pwd)/patches:/src/patches:z -it --rm --name firefox-build --hostname firefox-build firefox-build:fedora

python3 bootstrap.py --no-interactive --application-choice browser

Build

Update your mozconfig, if you want. Then execute the snippet below.
When asked for Destination directory for Git clone, enter nothing (hit enter).

DOCKER_BUILDKIT=0 docker build -t firefox-build:fedora .
docker run -v $(pwd)/dist:/dist:z -v $(pwd)/mozbuild:/root/.mozbuild:z -v $(pwd)/mozilla-unified:/src/mozilla-unified:z -v $(pwd)/mozconfig:/src/mozconfig:z -v $(pwd)/patches:/src/patches:z -it --rm --name firefox-build --hostname firefox-build firefox-build:fedora
cd mozilla-unified
build-prepare.sh
apply-patches.py
build.sh
exit
./install.sh # you may run this with sudo if your current user is not permitted to write into the installation directory (default is ~/bin/)

Troubleshooting

Compile error: error: options -C embed-bitcode=no and -C lto are incompatible

This "issue" came up with the release of Rust 1.45.

Bugzilla issue

My workaround; downgrade Rust to 1.44.1:

# run this after "bootstrap" and before "./mach build"
source ~/.cargo/env
rustup default 1.44.1

No rule to make target 'alg2268.c', needed by 'alg2268.obj'. Stop.

My workaround;

./mach clobber
# continue #Build section with `build-prepare.sh`
