Installing Firefox 7 on CentOS 5 and 6 and RHEL

Update: See newer post for instructions on installing Firefox/Thunderbird 10 on CentOS and RHEL.

As of writing, the latest version of Firefox for CentOS is 3.6.22, and the Mozilla team released version 7 of the Firefox browser earlier this week. Obviously, the CentOS repository is slightly behind in keeping Firefox updated. However, if you wish to upgrade to Firefox 7, the process is quite simple. This tutorial has been tested on CentOS 5 and 6, under both 32 bit and 64 bit.

Update: This has also been tested successfully on 64bit RHEL 6.

The installation process varies slightly based on whether you are using 32 bit or 64 bit.

Download Firefox

32 bit:

wget ''

64 bit:

wget ''

Unzip Firefox

tar xf firefox-7.0.1.tar.bz2

Move Firefox to the proper directory

32 bit:

sudo mv firefox /usr/lib/firefox-7.0

64 bit:

sudo mv firefox /usr/lib64/firefox-7.0

Modify the Firefox command to use the new version of Firefox

sudo perl -pi -e 's/3.6/7.0/g' /usr/bin/firefox

Clean up unnecessary files

rm -rf firefox-7.0.1.tar.bz2
