    1. This has been very useful. I have really searching for very long until I came to this post. Now I am able to run firefox 8 on my Cent OS 6.

      Thank you very much.

    2. Worked great in PUIAS 6.1 too.

    3. […] Re: CentOS 6 – VMware Player Basta installare il pacchetto da YUM, qui un link a posta per te, esiste comunque alche il wiki di CentOS Install Firefox 8 on Fedora 16/15, CentOS/Red Hat (RHEL) 6 […]

    4. Does not work as written for Fedora 13.

      ## Remi Dependency on Fedora 14, Fedora 13, Fedora 12 ##
      rpm -Uvh
      rpm -Uvh

      When I run these commands I get the following error:
      # rpm -Uvh
      warning: /var/tmp/rpm-tmp.ITQqFV: Header V3 RSA/SHA256 Signature, key ID f09d8368: NOKEY
      error: Failed dependencies:

      system-release >= 14 is needed by rpmfusion-nonfree-release-14-2.noarch

      I’ll try doing an update to my system…

      • Hi Susan,

        Thanks for the notification. Actually yes, there is no more RPMFusion repositories for Fedora 12 and Fedora 13. So try to skip this RPMFusion part and install just Remi repository directly, with following command:

        rpm -Uvh

        Then continue installation normally.

        And if you could confirm is this working normally? I update then this guide and other guides too.

    5. Gracias, funciona perfecto en fedora 14.

    6. Thank you for your helpful guide. I love CentOS 6 more than anything else, unfortunately however, it is very difficult for me to get my ZTE 3G modem to work in it….so I had to go back to Fedora, no more ubuntu….

    7. […] install Chromium. To update to the new version of Firefox you need to follow the instructions here worked perfectly. I didn’t bother trying to install Chromium as I already had my eye on […]

    8. Installed this onto CentOS 6.1 as root. Works fine if you launch it as root. However if you launch as a user it still launches the old version. Even after I have completed removed the old firefox 3 RPM. Still trying to track down why this is:

      yum list firefox
      Loaded plugins: fastestmirror, refresh-packagekit
      Loading mirror speeds from cached hostfile
      * base:
      * epel:
      * extras:
      * updates:
      Installed Packages
      firefox.x86_64 8.0-1.el6.remi @remi
      Available Packages
      firefox.i686 3.6.24-3.el6.centos updates

      • Hi Brad,

        Are you running 32-bit (i686) or 64-bit (x86_64) system?

        Your yum list firefox command shows that you have firefox.i686 3.6.24-3.el6.centos available and firefox.x86_64 8.0-1.el6.remi installed…

        • 64 bit.

          rpm -qa | grep firefox

          I completed removed firefox from my system. Would not launch any longer. Then installed the firefox-8.0-1.el6.remi.x86_64 rpm. When I launch firefox as a user it still launches the 3.6.24 x86_64 version. However when I su to root it launches the 8.0.1 version. I modified the firefox script to turn on debugging and here is the exec line:

          /usr/lib64/firefox/ /usr/lib64/firefox/firefox

          Which is identical to the root exec line.

          Additional debugging:
          /usr/lib64/firefox/ -g /usr/lib64/firefox/firefox

          /usr/lib64/firefox/ -g /usr/lib64/firefox/firefox

          I’ve done a lot of debugging of startup scripts, etc. And still can’t see where it launches this version from.


          • Hi again Brad,

            Ok, this sounds that the old version of Firefox is running on background…so that’s why normal user always starts old version and root new. If reason is this, then try following:

            killall firefox

            and then try to start it again…?

            Or alternatively logout/log in…or even reboot your box? :)

    9. hi,

      I’m using F16 x86_64 and firefox x86_64 8.0-3.fc16 (says yum list firefox)

      today on appeared an update

      I tried to update firefox with “yum update firefox”, but yum says “no packages marked for update”

      Am I missing something or doing wrong?



      • Hi RFederer,

        If you want to install Firefox 9 on Fedora 16 now, then you have to download that build manually and just install it…

        I update this guide when it appears updates-testing repo / remi repo.

        • thanks for your quick reply,

          all right, then…looking forward to your new guide :)


          • You are welcome!

            I think that the Firefox 9 is coming soon on updates-testing repo… :)

    10. Hi, first of all thanks for this guide & this is very useful especially for new linux users like me, ok now I’ve installed firefox 9.0 as per instructions in RHEL SERVER 6.2, when I launched from the command line it was launched, but when I try to create shortcuts in main menu & desktop it didn’t work. So I was able to use it only by launching from command line “/opt/firefox/firefox”, now after I restarted the system I’m getting the old dreaded error of “/opt/firefox/firefox: error while loading shared libraries: cannot open shared object file: No such file or directory” for which I couldn’t find any solution on the internet so that I could install firefox in my linux system until I come to this post.

      So can you suggest me on the possible reason of firefox not working after system restart & how to get rid off error

      • Hi Satish,

        If your install Firefox with this guide on Red Hat (RHEL) 6.2, then you should have/run /usr/bin/firefox not /opt/firefox/firefox…?

    11. great guide, thanks a lot!!!

      • You are welcome! :) Soon you can get Firefox 9 also from f16-updates / f15-updates repo…

        • is there any difference?

          I mean, I’m using fc16.x86_64 and yum says I installed this:

          Firefox.x86_64 9.0-2.fc17 @rawhide

          for the next update it’s pretty simple, just using:

          yum –enablerepo=rawhide update firefox

          Is there any danger using rawhide repo, fc becoming unstable?


          • Actually you could just use your Firefox, without updating it from rawhide repo. If example Firefox.x86_64 9.0-4.fc16 build is first build on Fedora 16 updates repo, then it should override your Firefox.x86_64 9.0-2.fc17 version just with normal yum update or yum update firefox, because it’s newer version… :)

            If you update your Firefox using rawhide, then next version is soon Firefox 10 beta and so on…so rawhide version might be latest stable or totally unstable version… ;)

            You could check Fedora Firefox builds from here. Example currently newest build is Firefox.x86_64 9.0-3.fc17 / Firefox.x86_64 9.0-3.fc16, but fc16 build is still marked as f16-updates-candidate and f16-updates-pending, so it’s not updating your Firefox now, only if it’s moved f16-updates repo.

            • thanks for the infos :)

              like you said, I’ll try to update to Firefox.x86_64 9.0-4.fc16 over yum update firefox if it’s moved to f16-updates repo…


    12. Works like a charm!

    13. I have just installed Fedora 16 (64 bit), plus Firefox 9 has installed and all updates applied. It seems to work ok, apart from the problem none of the many Firefox plugins can be installed. I usually find they do install under other O/s versions, but on Fedora 16, they won’t even attempt to download.
      Is there another method to install Firefox plugins ?

      Do I need to add my user account to administration group?

      • Just found my own answer.
        For each plugin link, I need to right click it and choose open in new tab.
        Then the new tab actually runs the download and installs the plugin.

        Slight bug I think in the way Firefox 9 works links.

        Firefox 9 also seems to jump from one of my screens to the other when firefox is restarted.
        I have my main screen as the VGA port and the secondary screen on DVI.

        When I restart Firefox after adding a plugin or other, Firefox is not opening up again on the same screen it was running on, (even my default screen which is on the VGA port of the graphics card), instead firefox isjumping to the other output screen.

        Then if I right click on the Firefox title bar and click on unmaximise, firefox minimises to the the other screen.

    14. It happens that we have to re-register the damned java plugin for each machine that have upgraded its firefox.

      I’d say do not upgrade to firefox9 unless you can afford the downtime or the oracle and Mozilla team produce an automated solution .

      • Hi tony,

        Really? I have upgraded some Firefox installations to Firefox 9 version and all existing Java (plugin) installation works ok…

        • I think he could be refering to the 64-bit versions.

          • Hi chen,

            I have of course upgraded 64-bit systems and no problems at all.

    15. Thanks a lot! It works great! Great explanation!
