Firefox-115.8.0esr

Installation de Firefox

La configuration de Firefox se fait en créant un fichier mozconfig contenant les options de configuration désirées. Un mozconfig par défaut est créé ci-dessous. Pour voir toute la liste des options de configuration disponibles, (et une description abrégée de chacune), faites ./mach configure --help | less. Il se peut que vous vouliez aussi relire tout le fichier et dé-commenter les autres options souhaitées. Créez le fichier en tapant la commande suivante :

cat > mozconfig << "EOF"
# If you have a multicore machine, all cores will be used by default.

# If you have installed (or will install) wireless-tools, and you wish
# to use geolocation web services, comment out this line
ac_add_options --disable-necko-wifi

# API Keys for geolocation APIs - necko-wifi (above) is required for MLS
# Uncomment the following line if you wish to use Mozilla Location Service
#ac_add_options --with-mozilla-api-keyfile=$PWD/mozilla-key

# Uncomment the following line if you wish to use Google's geolocation API
# (needed for use with saved maps with Google Maps)
#ac_add_options --with-google-location-service-api-keyfile=$PWD/google-key

# startup-notification is required since firefox-78

# Uncomment the following option if you have not installed PulseAudio and
# want to use alsa instead
#ac_add_options --enable-audio-backends=alsa

# Comment out following options if you have not installed
# recommended dependencies:
ac_add_options --with-system-icu
ac_add_options --with-system-libevent
ac_add_options --with-system-libvpx
ac_add_options --with-system-nspr
ac_add_options --with-system-nss
ac_add_options --with-system-webp

# Unlike with thunderbird, although using the gold linker can
# save four megabytes in the installed file it does not make
# the build faster.

# The libdav1d library (av1 decoder) requires nasm. Uncomment this
# if nasm has not been installed. Do not uncomment this if you have
# ffmpeg installed.
#ac_add_options --disable-av1

# You cannot distribute the binary if you do this.
ac_add_options --enable-official-branding

# Stripping is now enabled by default.
# Uncomment these lines if you need to run a debugger:
#ac_add_options --disable-strip
#ac_add_options --disable-install-strip

# Disabling debug symbols makes the build much smaller and a little
# faster. Comment this if you need to run a debugger. Note: This is
# required for compilation on i686.
ac_add_options --disable-debug-symbols

# The elf-hack is reported to cause failed installs (after successful builds)
# on some machines. It is supposed to improve startup time and it shrinks
# libxul.so by a few MB.  With recent Binutils releases the linker already
# supports a much safer and generic way for this.
ac_add_options --disable-elf-hack
export LDFLAGS="$LDFLAGS -Wl,-z,pack-relative-relocs"

# The BLFS editors recommend not changing anything below this line:
ac_add_options --prefix=/usr
ac_add_options --enable-application=browser
ac_add_options --disable-crashreporter
ac_add_options --disable-updater

# Enabling the tests will use a lot more space and significantly
# increase the build time, for no obvious benefit.
ac_add_options --disable-tests

# This enables SIMD optimization in the shipped encoding_rs crate.
ac_add_options --enable-rust-simd

ac_add_options --enable-system-ffi
ac_add_options --enable-system-pixman

ac_add_options --with-system-jpeg
ac_add_options --with-system-png
ac_add_options --with-system-zlib

# Sandboxing works well on x86_64 but might cause issues on other
# platforms. If not on x86_64, e.g. i686, it is recommended to
# uncomment the following switch.
#ac_add_options --disable-sandbox

# Using sandboxed wasm libraries has been moved to all builds instead
# of only mozilla automation builds. It requires extra llvm packages
# and was reported to seriously slow the build. Disable it.
ac_add_options --without-wasm-sandboxed-libraries

# The following option unsets Telemetry Reporting. With the Addons Fiasco,
# Mozilla was found to be collecting user's data, including saved passwords and
# web form data, without users consent. Mozilla was also found shipping updates
# to systems without the user's knowledge or permission.
# As a result of this, use the following command to permanently disable
# telemetry reporting in Firefox.
unset MOZ_TELEMETRY_REPORTING

Si vous construisez avec le ICU du système, adaptez la correspondance des sauts de ligne pour ICU 74 et supérieur. Cette construction ajoute cinq entrées à un tableau c++.

Compilez Firefox en exécutant les commandes suivantes :

Si vous avez besoin des API de géolocalisation :

echo "AIzaSyDxKL42zsPjbke5O8_rPVpVrLrJ8aeE9rQ" > google-key
echo "613364a7-9418-4c86-bcee-57e32fd70c23" > mozilla-key

Invoquez maintenant le script Python mach pour compiler le paquet.

export MACH_BUILD_PYTHON_NATIVE_PACKAGE_SOURCE=none &&
export MOZBUILD_STATE_PATH=${PWD}/mozbuild          &&
export PYTHON311=/opt/python3.11/bin/python3.11     &&
$PYTHON311 ./mach build

Le fichier mozconfig ci-dessus désactive les tests car ils prennent beaucoup plus de temps et d'espace disque sans bénéfice évident. Si vous les avez tout de même activés, vous pouvez lancer les tests en exécutant ./mach gtest. Cela requiert une connexion internet et d'être lancé dans un environnement Xorg - il y a une boîte de dialogue lorsque la connexion à ALSA échoue (ce qui ne fait pas échouer le test). Un ou deux tests échoueront. Pour voir les détails des échecs, vous devrez enregistrer la sortie de la commande pour pouvoir la revoir.

Maintenant, en tant qu'utilisateur root :

export MACH_BUILD_PYTHON_NATIVE_PACKAGE_SOURCE=none &&
export PYTHON311=/opt/python3.11/bin/python3.11     &&
$PYTHON311 ./mach install

Videz les variables d'environnement qui ont été définies plus haut :

unset MACH_BUILD_PYTHON_NATIVE_PACKAGE_SOURCE
unset MOZBUILD_STATE_PATH
unset PYTHON311
