How to Install Firefox 4 in Fedora, RHEL and CentOS?

Mozilla Firefox 4 has finally been released after such a long development cycle, when compared to the development of the recent releases of Internet Explorer and Google Chrome.
For those who have been waiting all this time. It can be painful waiting for the new version of Firefox to show up on the default repositories.
Here is a way to install the new Firefox 4 without having to wait,

  • Backup Firefox Settings

  • Take a backup of your current Firefox user profile and settings. Even though it’s generally safe to skip this step, as the settings will stay on the computer even if your uninstall Firefox. It’s always better to be safe then sorry.
    tar cvzf firefox-backup.tar.gz ~/.mozilla

  • Install Third-Party Spot Repository

  • Install the Spot Repository. Third party repositories generally are updated faster then the default repositories. So sometimes third party repositories are needed if you wanted the latest software as soon as they are released.
    su -c 'wget http://repos.fedorapeople.org/repos/spot/firefox4/fedora-firefox4.repo -O /etc/yum.repos.d/fedora-firefox4.repo'

  • Remove Current Firefox Installation (Optional)

  • Remove your current Firefox installation. If you plan on having more then one Firefox installation then you can skip this step.
    su -c 'yum remove firefox'

  • Enable the Repository

  • The repository will need to be enabled before we can use it.
    su -c 'yum –enablerepo fedora-firefox4'

  • Install New Firefox 4

  • Install the new Firefox 4 package onto your system and enjoy!!
    su -c 'yum install firefox4'
