follow site This will open up the Profile Manager. What you need to do is create a profile for each version you plan on running. So click "Create Profile", and then enter your profile name. I recommend naming it something like Firefox35, Firefox36, etc. so it's easily identifiable. Click "Finish" and make sure to check the "Don't ask at startup" box ;)

The key to making it work for us developers is to augment the shortcut target with a couple parameters that will auto-load a specific profile (i.e., -P, & -no-remote)

Right-click your shortcut icon, click Properties, and modify the "Target" value like so:

enter "C:\\Program Files\\Mozilla Firefox3.5\\firefox" -P FireFox35 -no-remote

The -P allows you to choose the profile, and the -no-remote allows you to run muiltiple versions at the same time. Also, remember to install each different version in a different folder. I have only ever done this for Windows however now that I'm running Mac OS X as well, I'll try and come back to this post and add some updates. I hope this was helpful!

    الخيارات الثنائية احتيال It’s not necessary to use the -no-remote parameter.
    This parameter is for running the same Firefox version multiple times with different profiles.

    الخيارات الثنائية انسحاب الفوري If you are running different Firefox versions you do not need -no-remote
    This has the added advantage that you can then start new windows by launching the shortcut again (with -no-remote you will get an error message if you try to do this).

    • Brad says:

      follow site So then, we don’t need to modify the shortcut/target at all, nor use the profile manager, if each version of FF is installed in its own folder? ie. We install FF 3.5 in its own folder with the installed shortcut on the desktop. Then we install FF 4 in its own folder with the installed shortcut on the desktop. Launching each of these shortcuts would run its respective version of FF simultaneously?

      • Rolf says:

        No, the default install will have a start menu shortcut follow url without the -P profile parameter. Extensions that only work with a certain Firefox version will mess up the install. Typically they will be de-activated if the (default) profile is used with the newer version … and stay de-activated also with the old version.
        You need an installation folder and a profile folder for each version.

    • This is incorrect. Without the -no-remote parameter, only the latest version you have installed will open regardless of the shortcut you click.

    thanks!
    it works perfect!

  8. Jong SP says:

    The instructions are clear. Actually, I’ve successfully created 2 profiles and successfully launch it with my existing Firefox3.

    However, when I tried to install the latest version of Firefox (Firefox Setup 8.0.1), it does not proceed with no error message. Would you know how to resolve this issue?

    Thanks.

  15. Skye_Wyven says:

    I’m currently running FF17 (at least, that’s what it tells me) and I just tried doing this so I can install and run an older version of FF. However, when I type the command to open the profile manager I get a message saying the path is invalid. I’ve tried looking for the file manually but I can’t seem to find it. Can you offer any suggestions?

    BTW I’m not a developer or programmer, this is for other reasons. Thank you!

    • @Skye_Wyven I’ll have to update my FF version and check. I honestly haven’t checked this in a while however I do have 3.6, 9, and 12 running at the same time just fine.

    • Scott says:

      @Skye_Wyven – It worked fine for me on Win7 using FF17.0.1.
      Make sure the command line path is correct for YOUR install location. For example, on my machine I have FF17 installed in it’s own folder, so my command looks like this:

      “C:\\Program Files\\Mozilla Firefox17\\firefox” -profilemanager -no-remote

      Good luck! -Scott

    WHOOT!!! Thanks for your advice.

    I’ve been trying to figure out how to run “stable” Firefox, “beta” Firefox, and Aurora for some time for a few years. I had given up until I started developing two web sites. I want to ensure that the sites work with every possible browser. This is great!
