    4. what you are installing by installing fedora-release-rawhide is the rawhide repository. and you are enabling with yum a single time to update.

    5. Hi Brandon, nice to see you here,

      Nice tip, but a few problems what came to my mind when using rawhide repository. I guess that rawhide installation will replace Firefox 3 installation, because it’s named just a firefox? And another problem is installation on Fedora 12, Fedora 13 and Fedora 14 distributions, I guess that, this rawhide method is not working on Fedora 12? And soon it will not either work on Fedora 13?

    9. I guess this Firefox 4 (from remi) will use the previous profile (default). So, if i start Firefox 3.6.x again it may complain.

      Am I right ?

      • Hi Imtiaz Rahi,

        Yes this is true. If you have any problems with this, then it is better to use the Firefox Profile Manager and create a new profile for Firefox 4.

        Start profile manager with following command:

        
        firefox --ProfileManager
        

        Create new profile example with name FF4

        Then start Firefox with FF4 profile using command:

        
        firefox4 -P FF4
        

        And start Firefox 3.6.x with command:

        
        firefox -P default
        

        I updated this guide also. Thanks!

      • Hi culpritz,

        Did you make a new profile (example FF4) with ProfileManager?

        And note, you have to close all Firefox 3.5 windows before starting Firefox 4.

    12. Hey thanks for this info.

      I already knew about the profile manager, but do you know how to use -no remote in Fedora 14 for Firefox so that I can run multiple instances?

      There’s this here,
      http://kb.mozillazine.org/Run_multiple_instances_in_Linux

      But, I’m very green to Linux and was wondering if you’ve tried it and used it successfully.

      • Hi SIFE,

        CentOS 5 does not meet the Firefox 4’s requirements.

        Firefox 4 needs libstdc++ 4.3 or higher and CentOS 5.x and Red Hat (RHEL) 5.x distros have libstdc++ 4.1.2. And yes, it’s of course possible install manually newer libstdc++, but it might break something else. So if you want keep your CentOS stable, then I it’s probably better not to install newer libstdc++ package.
