**ramsun** · 28-04-2012

I wanted to install the latest version of Firefox and it promises for the first time, manage memory much better and so do not consume all computer resources within hours of work with this browser. In one of my computers I use GNU / Linux CentOS 6 which is mainly focused on servers and updates directly from Red Hat line. For this reason the software versions are slow to update. Unfortunately the version of Firefox that includes the current version of CentOS is 3.6.9 so you can assume it will take quite reach the 6.0.

This article explains the steps to manually install Firefox 6.0 on CentOS 6, but these steps can be implemented generically in most major Linux distributions.

Get Firefox.
Download the latest distribution package of Firefox for Linux on the language you want. In my case I got firefox-6.0.tar.bz2 file after download.

Install Firefox.

This will install the newly downloaded version of Firefox under / opt.

Code:

# Firefox-6.0.tar.bz2 tar xjvf 
# Mkdir-p / opt / firefox / 
# Mv firefox / / opt/firefox/6.0 /

It removes the executable displayed by the previous version of Firefox.

Code:

# Mv / usr / bin / firefox / usr/bin/firefox_3.6.9

Establish alternative versions.

Alternatives are used to differentiate versions of Firefox installed and choose one as active as desired. To do this you create the two alternatives.

Code:

# Alternatives-install / usr / bin / firefox firefox / usr/lib/firefox-3.6/firefox 1 
# Alternatives-install / usr / bin / firefox firefox / opt/firefox/6.0/firefox 2

Finallyversion 6.0 is configured as an active alternative.

Code:

# Alternatives-config firefox

There are 2 programs Which Provide 'firefox'.

Code:

Selection Command 
---------------- 
1 / usr/lib/firefox-3.6/firefox 
2 / opt/firefox/6.0/firefox

Enter to keep the current selection [+], or type selection number: 2
