On a x86-64 64 bit Linux system, sometimes we may want to use the 32 bit Firefox, although the support to 64 bit Firefox is getting much better. Just for needed ones, this post introduces how to install 32 bit Firefox on 64 bit Linux (Fedora as the example).
Install 32-bit firefox
First, install firfox.i686 package.
# linux32 # yum install firefox.i686
Firefox can simply run now. But we still need to fix some issues.
When run firefox, we may get these warnings:
(firefox:4860): Gtk-WARNING **: Unable to locate theme engine in module_path: “clearlooks”,
Gtk-Message: Failed to load module “pk-gtk-module”: libpk-gtk-module.so: cannot open shared object file: No such file or directory
Gtk-Message: Failed to load module “canberra-gtk-module”: libcanberra-gtk-module.so: cannot open shared object file: No such file or directory
To fix these warnings, install needed packages:
# yum install libcanberra-gtk2.i686 gtk2-engines.i686 PackageKit-gtk-module.i686
However, there is no input method. To enable ibus-gtk2 input method in 32bit Firefox, install the ibus-gtk2 package
# yum install ibus-gtk2.i686
Install the flash-plugin
Enable rpmfusion repository: Enable RPM Fusion repositories
Install flash plugin
# yum install flash-plugin.i386
Set up flash plugin
There is no sound in flash. For sound support and curl support, install
# yum install alsa-plugins-pulseaudio.i686 curl.i686
You should have sound. flash-plugin works.
Firefox should complain nothing and work well now. Enjoy it.
Force to run firefox in 32-bit mode:
#!/bin/bash setarch i686 firefox -new-tab $*
