Building Firefox, SeaMonkey and Thunderbird from mercurial repositories

Build esr, release, beta, or central from the mozilla-unified repository.

SeaMonkey is no longer maintained in the comm-.... repositories, so to build an historical version, checkout an earlier revision of this page.

This page has been laid out around a mainly distro-independent build script, defaulting to an en-US build on unmodified source.
Packaging is Slackware specific, but installation for that is to DESTDIR, so I guess would be adaptable to other packaging systems.

Build Firefox with gtk3, using mach, and rust; and package it to install to /opt/firefox-{version} ...
and/or Thunderbird based on that mozilla source.

Builds default to x86_64 with additional setting up for cross compiling Firefox & Thunderbird for aarch64 [optimized for Raspberry Pi3], or i686.

Customization options with user preferences and single localization.

Build times

Mercurial bundles and repositories
mozilla-unified is downloaded as a compressed bundle [~1GB] and is unbundled to a sub-directory of $MOZBUILD.
The key advantage of using a bundle rather than cloning the repo is that an interrupted download can be resumed.
It also puts less of a load on the server - see here and here.
Requires mercurial with zstd support [v4.1.2 works], otherwise view 'bundles' file and choose compression type.
cd $MOZBUILD/sources ## get mozilla-unified bundle wget -O bundles https://hg.cdn.mozilla.net/ BUNDLE=$(grep mozilla-unified.*zstd bundles | sed 's|.*href="||;s|">.*$||') wget -O mozilla-unified.bundle https://hg.cdn.mozilla.net/$BUNDLE cd $MOZBUILD ## unbundle mozilla-unified hg init mozilla hg unbundle sources/mozilla-unified.bundle -R mozilla ## set default repo to pull from echo "[paths] default = https://hg.mozilla.org/mozilla-unified/" > mozilla/.hg/hgrc ## get new changesets since bundle was created hg pull -R mozilla ## update local repo hg update -R mozilla
comm-$REL and locale have to be cloned as no bundle is available.
There is a comm-central bundle, but to keep things consistent, let's clone that too …
## Set which repositories to clone: REPOS=$REPOS (for repo in $REPOS do cd $MOZBUILD/$repo RELEASES="/releases" && [[ $repo == central ]] && unset RELEASES hg clone https://hg.mozilla.org${RELEASES:-""}/comm-$repo/ done)

non-US locale
Use l10n mozilla-central repository and revert as necessary to the revisions required as per l10n-changesets.json.
(cd $MOZBUILD/l10n/ hg clone https://hg.mozilla.org/l10n-central/$L10N/)

From Thunderbird 113, localization for calendar, chat, and mail has been moved to a project repository
(cd $MOZBUILD/ hg clone -U https://hg.mozilla.org/projects/comm-l10n/)

Once these locally cloned repositories have been set up, they can be kept up-to-date for future builds - see 'Add new changesets'.

Latest versions of rust can cause build problems, so let's use the minimum required for the mozilla build:
grep MINIMUM_RUST_VERSION $MOZBUILD/mozilla/python/mozboot/mozboot/util.py

Rust
Download and install the x86_64 version of rust which includes the rustc and cargo binaries, and the x86_64 crate.
Aarch64, armv7[hf], and i686 crates for cross compiling will be downloaded and added to this installation as required. cd $MOZBUILD/sources/ wget -O rust.html https://forge.rust-lang.org/infra/other-installation-methods.html URL=$(sed 's|https|\n&|;s|tar.gz|tar.xz|' rust.html | grep -o https://.*$ARCH-unknown-linux-gnu.tar.xz |head -n1) ## check for latest version and adjust if the minimum version is required - ## will be something like https://static.rust-lang.org/dist/rust-1.70.0-x86_64-unknown-linux-gnu.tar.xz echo $URL wget $URL tar xf rust*$ARCH-unknown-linux-gnu.tar.xz cd rust*$ARCH-unknown-linux-gnu ./install.sh --prefix=$MOZBUILD/sources/rust-$ARCH --components=rustc,cargo,rust-std-$ARCH-unknown-linux-gnu
As rustc and cargo are installed off-PATH, their locations are included in mozconfig.common.

Check the minimum versions of nodejs and cbindgen required for the build:
grep 'NODE_MIN_VERSION =' $MOZBUILD/mozilla/python/mozbuild/mozbuild/nodeutil.py grep 'cbindgen_min_version =' $MOZBUILD/mozilla/build/moz.configure/bindgen.configure

cbindgen - download, build, and install to the same directory as rustc & cargo, as a convenient place to put it
cd $MOZBUILD/sources ## for the latest version: wget -O cbindgen-releases.html https://github.com/mozilla/cbindgen/releases CBINDGEN_REL=$(grep -o expanded_assets.* cbindgen-releases.html | head -n1 | cut -d'"' -f1 | cut -d'/' -f2) echo $CBINDGEN_REL wget -O cbindgen-$CBINDGEN_REL.tar.gz https://github.com/mozilla/cbindgen/archive/refs/tags/$CBINDGEN_REL.tar.gz tar xf cbindgen-$CBINDGEN_REL.tar.gz cd cbindgen-[0-9]*/ PATH=$MOZBUILD/sources/rust-$ARCH/bin:$PATH cargo install --root $MOZBUILD/sources/rust-$ARCH cbindgen
As cbindgen is installed off-PATH, its location is included in mozconfig.common.

gcc optimization for HOST, so only use if building for same machine architecture
- will be overridden in mozconfig.cross if cross compiling
- should be something like:
 -march=core2 -mtune=core2
export OPTM=$(echo $(gcc -Q -O2 -march=native --help=target | grep -E "^ -march=|^ -mtune=" | tr -d [:blank:])) ## … and suppress [-w] compiler warnings which are only useful for developers … OPTM="$OPTM -w" echo $OPTM
- otherwise, if required, set OPTM=<user_defined> for 'target' machine …

Create mozconfigs
As there are common variables between the FF and TB builds, set up a common mozconfig
'mach' will install wherever '--prefix=' points to.
Other options can be seen in 'old-configure'

Gtk3 configuration  Not a part of the build, just some customization options, for example where the defaults for gtk2/gtk3 differ …

close [1] The tooltip box for the default gtk3 Adwaita theme has white text on a black background with some padding: which is set by the tooltip section in gtk/theme/Adwaita/gtk-contained.css in the gtk3 source: 
tooltip {
  padding: 4px;
  /* not working */
  border-radius: 5px;
  box-shadow: none;
  text-shadow: 0 1px black; }
tooltip.background {
  background-color: rgba(0, 0, 0, 0.8);
  background-clip: padding-box;
  border: 1px solid rgba(255, 255, 255, 0.1); }
tooltip decoration {
  background-color: transparent; }
tooltip * {
  padding: 4px;
  background-color: transparent;
  color: white; }
Overriding this in ~/.config/gtk-3.0/gtk.css with:
tooltip {
  border-radius: 5px;
  text-shadow: none;}
tooltip.background {
  background-color: #eee1b3;
  border-radius: 5px;
  border: 1px solid gray;}
tooltip * {
  padding: 0px;
  color: black;}
will show the tooltip as: [2] ~/.config/gtk-3.0/gtk.css To show scrollbar stepper icons, add: 
* {
  -GtkScrollbar-has-backward-stepper: true;
  -GtkScrollbar-has-forward-stepper: true; }
[3] /etc/gtk-3.0/settings.ini To scroll by one page when clicking in the scrollbar, add:
