  3. Does not work as written for Fedora 13.

    ## Remi Dependency on Fedora 14, Fedora 13, Fedora 12 ##
    rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
    rpm -Uvh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm

    When I run these commands I get the following error:

    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:

      Then continue installation normally.

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

  5. 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….

  6. 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: http://ftp.osuosl.org
    * epel: mirror.chpc.utah.edu
    * extras: mirror.steadfast.net
    * updates: mirrors.easynews.com
    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…

      Reply
      • 64 bit.

        rpm -qa | grep firefox
        firefox-8.0-1.el6.remi.x86_64

        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/run-mozilla.sh /usr/lib64/firefox/firefox

        Which is identical to the root exec line.

        Additional debugging:
        /usr/lib64/firefox/run-mozilla.sh -g /usr/lib64/firefox/firefox

        /usr/lib64/firefox/run-mozilla.sh -g /usr/lib64/firefox/firefox
        MOZILLA_FIVE_HOME=/usr/lib64/firefox
        LD_LIBRARY_PATH=/usr/lib64/firefox:/usr/lib64/firefox/plugins:/usr/lib64/firefox
        DISPLAY=:0.0
        DYLD_LIBRARY_PATH=/usr/lib64/firefox:/usr/lib64/firefox
        LIBRARY_PATH=
        SHLIB_PATH=/usr/lib64/firefox:/usr/lib64/firefox
        LIBPATH=/usr/lib64/firefox:/usr/lib64/firefox
        ADDON_PATH=
        MOZ_PROGRAM=/usr/lib64/firefox/firefox
        MOZ_TOOLKIT=
        moz_debug=1
        moz_debugger=
        moz_debugger_args=

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

        Thanks!

        • 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:

          and then try to start it again…?

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

  7. hi,

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

    today on http://koji.fedoraproject.org/koji/buildinfo?buildID=279519 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?

    thanks

    • 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 :)

  8. 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: libstdc++.so.6: 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 libstdc++.so.6 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…?

    • 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?

        regards

        Reply
        • 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.

          Reply
          • 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…

  11. 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?

    Reply
    • 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.
      weird

  12. 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…

  15. Hi,
    will this work on Centos 5.7?

    Reply
    • Hi Rod,

      Sorry, Firefox 9 is not working on CentOS 5.7. Enterprise Linux 5 is just too old to run Firefox 9.

      Here is Firefox 9 minimum system requirements on Linux…
      Firefox will not run at all without the following libraries or packages:
      GTK+ 2.10 or higher
      GLib 2.12 or higher
      Pango 1.14 or higher
      X.Org 1.0 or higher (1.7 or higher is recommended)
      libstdc++ 4.3 or higher
