LibreWolf build instructions

First, let's download the latest tarball. This tarball is the latest produced by the CI. You can also check the sha256sum of the tarball there.

So here is how build LibreWolf for Linux:

tar xf <tarball>
cd <folder>
make bootstrap setup-wasi build package run

How to make a patch:

The easiest way to make patches is to go to the LibreWolf source folder:

cd librewolf-$(cat version)
git init
git add <path_to_file_you_changed>
git commit -am initial-commit
git diff > ../mypatch.patch

We have Gitter / Matrix rooms, and on the website we have links to the various issue trackers.

Building LibreWolf with git:

1. Clone the git repository via https:

git clone --recursive https://gitlab.com/librewolf-community/browser/source.git

or ssh:

git clone --recursive git@gitlab.com:librewolf-community/browser/source.git

cd into it, build the LibreWolf tarball, bootstrap the build environment, and finally, perform the build:

cd source
make all
make bootstrap
make build

After that, you can either build a tarball from it, or run it:

make package
make run

How to create a patch for problems in Mozilla's Bugzilla.

Well, first of all:

• Create an account.
• Handy link: Bugs Filed Today.
• The essential: Firefox Source Tree Documentation.

Now that you have a patch in LibreWolf, that's not enough to upload to Mozilla. See, Mozilla only accepts patches against Nightly. So here is how to do that:

hg clone https://hg.mozilla.org/mozilla-unified
cd mozilla-unified
hg update
MOZBUILD_STATE_PATH=$HOME/.mozbuild ./mach --no-interactive bootstrap --application-choice=browser
./mach build
./mach run

Now you can apply your patch to Nightly:

patch -p1 -i ../mypatch.patch

Now you let Mercurial create the patch:

hg diff > ../my-nightly-patch.patch

And it can be uploaded to Bugzilla.

(copy of Mozilla readme) Now the fun starts

Time to start hacking! You should join us on Matrix, say hello in the Introduction channel, and find a bug to start working on. See the Firefox Contributors’ Quick Reference to learn how to test your changes, send patches to Mozilla, update your source code locally, and more.

Hey, I'm using a Mac or Windows :(

We understand, life isn't always fair 😺. The same steps as above do apply, you'll just have to walk through the beginning part of the guides for MacOS, Windows. To build on Mac/Windows is not very well tested. It should work, perhaps with the exception of the make setup-wasi step. Help testing with these targets is always welcome.
