Extracting the tarball will reset the permissions of the current directory to 0755 if you have permission to do that. If you do this in a directory where the sticky bit is set, such as /tmp it will end with error messages:

tar: .: Cannot utime: Operation not permitted
tar: .: Cannot change mode to rwxr-xr-t: Operation not permitted
tar: Exiting with failure status due to previous errors

This does finish with non-zero status, but it does NOT mean there is a real problem. Do not untar as the root user in a directory where the sticky bit is set - that will unset it.

As with other large packages which use C++ (or rust), the SBU times to build this vary more widely than you might expect. Also, almost 6GB of real memory is used during the final link and the SBUs can increase significantly if the machine has to swap to do this.

The mach build system (Python scripts) can be somewhat unreliable: if the build fails and reports an Error, it can still return a status of success, causing a scripted build to try to install (which does not rerun the build), fail during the preparations for installing, but still exit with a status of success. Also, on occasion it may limit itself to only running one set of jobs - that will make the build take about 3 times as long as running with four sets of jobs.

Although upstream prefer to use PulseAudio, for the moment Alsa can still be used. Both may need runtime configuration to get sound working.

Installation of Firefox

The configuration of Firefox is accomplished by creating a mozconfig file containing the desired configuration options. A default mozconfig is created below. To see the entire list of available configuration options (and an abbreviated description of some of them), issue ./mach configure && ./configure --help | less. You may also wish to review the entire file and uncomment any other desired options. Create the file by issuing the following command:

cat > mozconfig << "EOF"
# If you have a multicore machine, all cores will be used by default.
# You can change the number of non-rust jobs by setting a valid number
# of cores in this option, but when rust crates are being compiled
# jobs will be scheduled for all the available CPU cores.
#mk_add_options MOZ_MAKE_FLAGS="-j1"

# If you have installed dbus-glib, comment out this line:
ac_add_options --disable-dbus

# If you have installed dbus-glib, and 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

# Uncomment these lines if you have installed optional dependencies:
#ac_add_options --enable-system-hunspell

ac_add_options --with-system-libvpx
ac_add_options --with-system-nspr
ac_add_options --with-system-nss
ac_add_options --with-system-icu

# If you are going to apply the patch for system graphite
# and system harfbuzz, uncomment these lines:

# Stripping is now enabled by default.
# Uncomment these lines if you need to run a debugger:

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

# Optimization for size is broken with gcc7 and later

ac_add_options --enable-official-branding

# From firefox-61 system cairo is not supported

Compile Firefox by issuing the following commands:

If you have installed system versions of graphite2 and harfbuzz and wish firefox to use those instead of its shipped versions, apply the patch and uncomment the appropriate entries in the mozconfig file.

patch -Np1 -i ../firefox-62.0-system_graphite2_harfbuzz-1.patch

注記

If you are compiling Firefox in chroot, make sure you have $SHELL environment variable set or prepend SHELL=/bin/sh.

Invoke the Python script to compile the package:

./mach build

The mozconfig above disables the tests because they use a lot more time and disk space for no obvious benefit. If you have nevertheless enabled them, you can run the tests by executing ./mach gtest. This will require a network connection, and to be run from within an Xorg session - there is a popup dialog when it fails to connect to ALSA (that does not create a failed test). One or two tests will fail. To see the details of the failure(s) you will need to log the output from that command so that you can review it.

Now, as the root user:

./mach install                                                  &&

mkdir -pv  /usr/lib/mozilla/plugins                             &&
ln    -sfv ../../mozilla/plugins /usr/lib/firefox/browser/

Command Explanations

./mach build: Firefox now uses this python2 script to run the build and install.

./mach build --verbose: Use this alternative if you need details of which files are being compiled, together with any C or C++ flags being used.

mkdir -pv /usr/lib/mozilla/plugins: This ensures that /usr/lib/mozilla/plugins/ exists.

ln -sv ... /usr/lib/firefox/browser: This command creates a symbolic link to /usr/lib/mozilla/plugins. It's not really needed, as Firefox checks /usr/lib/mozilla/plugins by default, but the symbolic link is made to keep all the plugins installed in one folder.

Configuring Firefox

If you use a desktop environment like Gnome or KDE you may like to create a firefox.desktop file so that Firefox appears in the panel's menus. If you didn't enable startup-notification in your mozconfig change the StartupNotify line to false. As the root user:

mkdir -pv /usr/share/applications &&
mkdir -pv /usr/share/pixmaps &&

cat > /usr/share/applications/firefox.desktop << "EOF" &&

Configuration Information

The application settings for firefox are accessible by keying about:config in the address bar.

With this version of firefox, getting working sound can be a problem. Although upstream prefers pulseaudio, on balance using Alsa may be easier.

If you enabled Alsa for sound, you may need to alter one variable to get working sound. If you run firefox from a term and try to play something with sound you might encounter error messages like:

Sandbox: seccomp sandbox violation: pid 3941, tid 4030, syscall 16, args 48 2147767296 139909894784796 0 0 0.

That was on x86_64, on i686 the syscall number is 54. To allow this syscall, in about:config change security.sandbox.content.syscall_whitelist to 16 (or 54 if using i686).

If you use pulseaudio in a Desktop Environment, it might already be started by that DE. But if it is not, although firefox-57 managed to start it, firefox-58 does not. If you run firefox from a term, trying to play sound will encounter error messages warning Can't get cubeb context!

The fix for this is to close firefox, start pulseaudio to check it does start (if not, read the information on Configuring in PulseAudio-12.2) and restart firefox to check it is working. If it now works, add the following to your ~/.xinitrc: pulseaudio --verbose --log-target=syslog& (unfortunately, on some systems this does not work).

You may wish to use multiple profiles within firefox. To do that, invoke firefox as firefox --ProfileManager. You can also check which profile is currently in use from about:profiles.
