Windows 10 - 22 H2 - All updates applied AMD Ryzen 7950x + DDR5 64GB RAM + 3090 RTX GPU + Plenty of Disk Space Firefox

Hi,

To get myself off MS Edge (as its Chromium based), I've come back to FF. But after I tried installing firefox standard and even the Extended Support Release I can not run it for the first time - I get this error

Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I've followed the advice in the help pages, but it hasnt fixed the issue

https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

The same happens when I run

firefox -p

The firefox App Data folder contains no profile file at all....

C:\Users\marcu\AppData\Roaming\Mozilla\Firefox

Inside crash reports is an empty events folder, and two crash report instance files (once for each attempt to start up FF) For example

I've tried uininstalling and wiping all files, and I wanted to try an old versions BUT the link on the page is dead

https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/ - Gives me 404

Do I have some service not running that this relies on ?

@jscher2000 - You are correct, when using Windows explorer (with "show hidden" enabled) I can now see other subfolders. Looking at my user AppData subfolders I had a messed up Junction right here

C:\Users\marcu\AppData\Local\Mozilla

2021-08-08 06:17 PM <JUNCTION> Mozilla [X:\CUserMarcu\AppData\Local\Mozilla]

That was pointing to a missing folder location ie there is no X:\CUserMarcu\AppData\Local\Mozilla folder, I added a link to another disk for this folder a while ago in a previous install of Firefox, this was to reduce the backup sizes of my user folder.

Anyway I deleted this, and all sorted now, thanks a lot for being patient !

Do you have Firefox from the Mozilla server or the MSIX version Firefox from the Microsoft Store? The MSIX version has its profile in a different location.

You can check if you have an "Old Firefox Data" folder on the desktop in case the Refresh feature in Firefox has been used and a new profile has been created.

Hi,

I downloaded it from the Mozilla Server, and the folder that stores the profile has been created and is empty

C:\Users\marcu\AppData\Roaming\Mozilla\Firefox.old C:\Users\marcu\AppData\Roaming\Mozilla\Firefox

As I installed and uninstalled twice, both of these folders are from the 2 installs I have done where Firefox is failing to start due to the profile issue. Both do not have a profile in them, just the crash folder I mentioned above.

"You can check if you have an "Old Firefox Data" folder on the desktop in c"

I dont have any folder on my desktop from firefox, the folders are in the AppData folder.

Is there a registry setting thatcontains a path Firefox is using to find the profile ? Maybe from a previous Firefox installation, a reg entry that is maybe pointing to a folder where it is looking for my profile and that folder has now been removed ?

If you get the "profile cannot be loaded" message then this means that you have a profiles.ini that lists profiles and that the profile marked as "Default=1" is no longer present. You can remove profiles.ini to force Firefox to create a new default-release profile.

You can find the profiles.ini file in a hidden location:

  • Windows: %AppData%\Mozilla\Firefox\
    C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\

Note that Windows hides the .ini file extension.

Also I searched my entire C: partiton where my users folder c:\users is

C:\>dir /s profiles.ini

Volume in drive C is OSF
Volume Serial Number is EE6C-1E09

File Not Found

There are no file called profiles.ini anywhere on my partition where my users folder is. There is the folder the profiles ini is supposed to be inside, but no profiles.ini

I also searched the whole user folder as my user, and as an administrator

C:\Users>dir /s profiles.ini

Volume in drive C is OSF
Volume Serial Number is EE6C-1E09

File Not Found

All folders are empty? No installs.ini file either? Usually then Firefox would just create a new profile.

Although I think you should be seeing hidden files in the command window, "just in case", could you verify that Windows is not set to hide them in File Explorer:

Thank you for reporting back. I'm not familiar with junctions, and didn't realize a problem in the "Local" path could cause that error message. Always a new wrinkle.
