    cannot restore old firefox profile


    I realise this post is not exclusively related to Windows 10, but someone out there may be able to help me.

    I carelessly ended up with a virus today and it played havoc with my Firefox browser. Fortunately a couple of weeks ago I had saved a copy of my Firefox profile with all the bookmarks, extensions and passwords etc. . The problem is that when I place this profile file in its correct location, Firefox will not open. I receive a message saying that 'Your Firefox profile cannot be loaded. It may be missing or inaccessible.

    This situation is probably due to the fact that shortly after saving my Firefox profile, I created a new user account for Windows 10, and then changed its name via the Control Panel. The original name for the new account however still appears in File Explorer under C:\Users as I could not change it there.

    How can I get my original Firefox profile to open? I cannot understand why it is not working as it was fine until I got the virus earlier today.

    All suggestions gratefully received!!



    :)

    Ok This is solved now and here is how I managed to correct it on my own.

    I tried to uninstall Firefox and reinstall, this had no affect. I tried creating a new profile under Firefox, again now affect.

    Next I created a new user account in Windows. This then worked properly when logging into my bank after the first time it remembered me and no longer asked the challenge questions.

    I figured at this point that it may have been something with my old user account but I wanted to try one more thing before going through the pain of making this new account like the old one. So, I copied the new Firefox profile from my new user account over
    to my old user account . Then logged back into my old user account, and selected to use that Firefox profile. After doing that it now works properly. Why creating a new Firefox profile under my old user account won't work, I have no idea.

    Anyway this is what worked for me.

    Once you put your profile in the correct location ("C:\Users\UserName\AppData\Roaming\Mozilla\Firefox\Profiles" and renamed the original profile which you can later delete if you wish) copy the full name of the profile you wish to use open the profiles.ini file which is in the same folder with notepad and change the name of the original profile in Path=Profiles to the one you want save and it should work. You might need to take ownership of profiles.ini
