Building LibreWolf from source:

First, let's head over to the releases page; note and download the latest version. Once downloaded, extract it.

export version=$(cat version)
mkdir build
cd build

wget -q https://fresh.librewolf.io/librewolf-$(version)/librewolf-$(version).source.tar.gz
tar xf librewolf-$(version).source.tar.gz

Next step, if you have not done so already, you must create the build environment:

cp librewolf-$(version)/lw-assets/bootstrap.py .
python3 bootstrap.py --no-interactive --application-choice=browser

It takes about an hour for me to complete, but it needs to be done only once.

Now we're ready to actually build LibreWolf:

cd librewolf-$(version)
./mach build

Also takes me an hour. Then, we can run it:

./mach run

Or make a package:

./mach package

Building LibreWolf source tarball:

You don't need the build environment for this. If you don't have write access, just:

git clone https://gitlab.com/stanzabird/source.git
cd source
make all

If you do have write access, we're first gonna check for a newer version of Firefox:

git clone git@gitlab.com:<your_username>/source.git
cd source
make check

If there is a new version, it's a good time to git commit and trigger a CI build job.

git commit -am v$(cat version) && git push

To build the source archive:

make all
