Firefox-128.1.0esr

Instalação do Firefox

A configuração do Firefox é realizada criando-se um arquivo mozconfig contendo as opções desejadas de configuração. Um mozconfig padrão é criado abaixo. Para ver a lista completa de opções de configuração disponíveis (e uma descrição abreviada de algumas delas), emita ./mach configure -- --help | less. Você também possivelmente revise o arquivo inteiro e descomente quaisquer outras opções desejadas. Crie o arquivo emitindo o seguinte comando:

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

# Comment out the following line if you wish not to use Google's Location
# Service (GLS).  Note that if Geoclue is installed and configured to use
# GLS (as the BLFS instruction does), Firefox can access GLS via Geoclue
# anyway.  On the other hand if Geoclue is not installed (or not properly
# configured) and this line is commented out, the website requiring a
# location service will not function properly.
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

# 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.
ac_add_options --disable-debug-symbols

# 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, e.g. i686.
[ $(uname -m) != x86_64 ] && 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

Adapte dois arquivos para compatibilidade com cbindgen-0.27.0 ou posterior:

sed 's/input.try/&_parse/' \
    -i servo/components/style_traits/values.rs &&
sed '0,/"Keyframe"/{//d}' -i servo/ports/geckolib/cbindgen.toml

Se construir com o ICU do sistema, adapte o mapeamento de quebra de linha para ICU 74 ou posterior. Esta construção adiciona cinco entradas para um vetor c++.

for i in {43..47}; do
   sed -i '/ZWJ/s/}/,CLASS_CHARACTER&/' intl/lwbrk/LineBreaker.cpp 
done

Compile o Firefox emitindo os seguintes comandos:

Se as APIs de geolocalização forem necessárias:

echo "AIzaSyDxKL42zsPjbke5O8_rPVpVrLrJ8aeE9rQ" > google-key

Agora invoque o conjunto de comandos sequenciais Python mach para compilar o pacote.

export MACH_BUILD_PYTHON_NATIVE_PACKAGE_SOURCE=none &&
export MOZBUILD_STATE_PATH=${PWD}/mozbuild          &&
./mach build

O mozconfig acima desabilita os testes porque eles usam muito mais tempo e espaço em disco sem nenhum benefício óbvio. Se você, mesmo assim, os tiver ativado, poderá executar os testes executando ./mach gtest. Isso exigirá uma conexão de rede de intercomunicação e será executado a partir de uma sessão do Xorg - existe uma caixa de diálogo pop-up quando ele falha ao se conectar ao ALSA (isso não cria um teste com falha). Um ou dois testes falharão. Para ver os detalhes da(s) falha(s), você precisará registrar a saída gerada a partir desse comando, de forma que consiga revisá-la(s).

Agora, como o(a) usuário(a) root:

export MACH_BUILD_PYTHON_NATIVE_PACKAGE_SOURCE=none &&
./mach install

Esvazie as variáveis de ambiente que foram configuradas acima:

unset MACH_BUILD_PYTHON_NATIVE_PACKAGE_SOURCE
unset MOZBUILD_STATE_PATH
