Compile Firefox

From MEPIS Documentation Wiki

Jump to: navigation, search

Reason: if you want to try the latest 64 bit version that is not yet available in MEPIS or community repository you need to compile it yourself because Mozilla doesn't seem to provide binary builds for 64 bit releases. Another reason is to customize the build to your needs.


Install prerequisites

As root, run these commands (you need to have src repositories enabled in /etc/apt/sources.list, if you just enabled them you need to run "apt-get update" first), and may need to add "deb-src mepis8cr main non-free" to your sources.list:

apt-get build-dep iceweasel
apt-get install mercurial libasound2-dev libcurl4-openssl-dev libidl-dev libdbus-glib-1-dev

Create ~/.mozconfig file

This is a file used to set compilation options for Firefox, a generic one could look like this:

mk_add_options MOZ_CO_PROJECT=browser
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/ff-opt
ac_add_options --enable-application=browser
ac_add_options --enable-optimize=-O2
ac_add_options --disable-tests
ac_add_options --disable-debug
ac_add_options --enable-official-branding
ac_add_options --disable-crashreporter

You can find more details about this file at and you can try different options that are better suited for your needs.

Download sources and unpack

  • Download the desired version from [1]
  • Untar the package
tar xvf packagename
  • Move resulting folder to ~/mozilla
mv foldername ~/mozilla


This will take some time depending on your computer.

cd ~/mozilla
make -f build

Making an installation tarball

Change directory to your object directory ("~/mozilla/ff-opt" in case you use ~/.mozconfig posted here):

cd ~/mozilla/ff-opt

and run:

make package

This will create a tar.bz2 file in ~/mozilla/ff-opt/dist which you can then unpack anywhere. After the tar.bz2 file is created you can use the instructions from this page (starting with the second point) to install it.
