Firefox Is Now Built With Clang+LTO Everywhere, Sizable Performance Wins For Linux Written by Michael Larabel in Mozilla on 12 September 2018 at 05:33 AM EDT. Firefox nightly builds are now built with the LLVM Clang compiler on all major platforms and the Linux build in particular is also now utilizing PGO optimizations too. A wild qtwebengine appears! (seriously, it's even worse). It annoys me to no end that i need it for only one application, and that's anki (flashcards app). I finally decided to package precompiled version of it and it took much quicker to make an ebuld for it than to build the damn dependencies (pyqt5,qtwebengine). Especially since current version relies on deprecated pyqt4 + qtwebkit4 that.

If you are unsure what you need to download, please refer to the Gentoo Handbook for the complete installation documentation.
It explains how you can find the right architecture for your machine and which files you need at what stage of the installation process.

Advanced choices and other architectures

amd64 – Advanced choices

Details (contents, hashes, and signatures)

The amd64 architecture is intended for use on AMD 64-bit CPUs as well as 64-bit Intel Pentium/Core/Xeon processors.

x86 – Advanced choices

Details (contents, hashes, and signatures)

There are two builds of the x86 architecture: i486 and i686.
Processors prior to the Intel Pentium Pro or Pentium II require the i486 variant to be used.

arm

arm64

hppa

ia64

Details (contents, hashes, and signatures)

The ia64 architecture is intended for use on Intel Itanium processors only.
If you have a 64-bit Intel Pentium/Core/Xeon processor, you need to use the amd64 architecture.

Hardware compatibility

The lp64d stages can be used on all 64-bit RISC-V processors supporting the double-precision floating point instruction set. The lp64 stages can be used on all 64-bit RISC-V processors; they require no hardware support for floating point arithmetics.

For an overview of the different instruction sets, see, e.g., the RISC-V wikipedia page.

Additional Gentoo-specific information can be found on the web page of the Gentoo RISC-V project.

This page details how to build Firefox OS and flash it on your phone. Note that Firefox OS is not the Firefox web browser.

Requirements

Phone

• Obviously, you will need a smartphone supported by Firefox OS, see the list here.
• fastboot must be enabled, you may need to unlock the bootloader for that. This is out of the scope of this document.

Computer

• 64bit Gentoo with a multilib profile
• 4GB of RAM
• 30GB of disk space (sources alone take 14GB)

Packages

Quite a few packages are required, so we might as well create a set.

You also need the 32bit versions of ncurses and zlib.

adb/fastboot

Test adb

Check if adb detects your phone

Udev rule

Firefox Guide On The Firejail Wordpress

If your phone is not detected, you may need a new udev rule

Then retry to detect the phone.

Backing up your data

This backup can be used later to build Firefox OS because some non-free files are not included in the sources and must be extracted from a backup (or the phone directly)

Alternatively you can use this script to backup and restore user data.

Building Firefox OS

Find the phone's codename

See this table.

Choose a Firefox OS version

The list of versions available can be seen here.As of this writing, v2.2 is the lastest stable version but you can build any version you want.

Python

The script fetching the sources uses python, unfortunatly it only works with python2, if your default python interpreter is python3, you will need this small hack

Firefox Gentoo No Sound

GCC

Old versions of Firefox OS require GCC 4.6, the current master can be built with any modern version. See this MDN page for information on how to use older compilers if you need to build an older version.

Non-free files

Www-client/firefox – Gentoo Packages

To build Firefox OS you need some non-free files only present on the phone (or backups of the phone). If you did a backup, you can use it for the build by setting ANDROIDFS_DIR, otherwise you need to connect your phone via USB while building.

Fetching the sources

Download Mozilla Firefox For Windows 10 2017

Mozilla Firefox

The last command will start fetching the sources, this will take a very long time, possibly hours since it basically downloads 14GB of data.

Build

Building takes quite some time and displays a lot of warnings.

Flashing

Www-client/firefox-bin – Gentoo Packages

If all goes well, your phone should reboot on the new version of Firefox OS
