I had a problem where FF 140.0 would not update, and in trying to get FF yo update, I used a re-install tool to which I was pointed in my problem report. This caused FF to wipe out my configuration, and I lost all my windows and tabs. I have gone to

    \Appdata\Roaming\Mozilla\Firefox\Proifiles\abnfpged.default

cleared all of the data therein, and restored that directory from a backup I made last Monday. But I cannot get FF to use that directory. "about:profiles" shows only two profiles, but the Profiles directory has five profiles:

03/10/2026 09:39 AM <DIR> qf00ka5x.default 03/10/2026 09:39 AM <DIR> v842ceue.default-release 04/11/2026 09:16 PM <DIR> .. 04/11/2026 09:16 PM <DIR> . 04/12/2026 03:08 PM <DIR> abnfpged.default 04/12/2026 06:29 PM <DIR> jdfj91sd.default-release-1775960183850 04/12/2026 06:48 PM <DIR> f1jq4mlq.default

Only the profiles beginning with "j" and "f1" are seen in the "about:profiles" screenshot I have attached. And I have attached a screenshot of my profiles.ini file. Also, in the abnfpged.default directory I restored, where is the list of all of my open windows and tabs? FF used to keep that in a sessionstore.jsonlz4 file, but that file is only written when FF closes. I tried to save a copy when I was having problems, but I stored the copy in the same directory, which FF changed during the re-install process. Here is my profiles,.ini file:

[Install308046B0AF4A39CB] Default=Profiles/jdfj91sd.default-release-1775960183850 Locked=1

I have not worked with the ;profiles.ini file in many years, as my FF configuration has not had problems. Thanks.

Again, folloed Mozilla Support directions from Konstantina Papadea of 10/22. I could not type or paste anything to then get to "Enter/Return". Could not get to "About Profiles".

I did get a warning page from Webroot that there "might" be security issues. Please advise.

Am I seriously supposed to enter windows safe mode to delete this folder, my machine requires a bitlocker password for me to enter safe mode in windows. I could probably do it, but I do not understand why I have to go through this insane process to remove a folder from my desktop.

I cant believe this software is capable of making a completely unremovable folder on my desktop, I don't have permission to remove a folder from my own computer? Seriously? I'm supposed to go into recovery mode in windows just to delete some firefox folder? THIS IS INSANE.

I tried restarting, changing permissions, I get access denied error. Is there anything else I can do?

Who decided to attach everything in my browser to a profile that can be easily deleted???!?!?!? Just lost all of my work shit because I tried to turn off this dumb feature I wasn't using and now everything is gone!!! History, passwords, bookmarks, sessions, everything! Never even created any profile, the browser just updated and necxt day all of my settings were tied to this dumb bullshit. Stop moving all of my data without notice or permission.

Almost locked my out of my work email because it thinks this is a different device now!!!!!!! Fucking dumb!!

Once again the latest firefox browser has issues so I rolled back the last stable version. It keeps prompting me to create a new profile. I want to use the previous profile that has all my setting and bookmarks. I got to about:profiles and selected the profile i want to make default and it will not add it to firefox. How can I do this?

At first deployment of multiple profiles in early 2026, my use was really intuitive and I was able to understand the FAQ and Community notes. Early October, the releases started to implement some refinements. I am not understanding these refinements and while I am seeing the error message (attached), I am not understanding what the fix is to use my additional profiles (two), int the past month, I have not found a way to get to my two additional profiles.

My environment: Windows 11 Pro - Firefox 158.0 (64 bit) I have Profiles "Original" and two others. I have one single Mozilla account. I copied my two profiles from original and had made great progress culling the profile passwords and bookmarks, I have only been syncing my original profile two my two cellphones. 95% of my use is from desktop Firefox.

Attached is a well documented result error but I am not locating how to get to the profiles I had created from the attached error message.

Every time there is an update, Firefox creates a new profile and hides all passwords etc. It is therefore impossible to work with it now. With 157 I now have a worthless Firefox, because all links, passwords, settings etc have been cleared and a new profile has been created.

On linux, in the past, firefox kept all its data in home/{user}/.mozilla. This was changed at some pont to spread the data out into /home/{user}/.config, /home/{user}/.cache and maybe another place but when the change was made existing data was not moved and remained in /home/{user}/.mozilla. For my purposes I prefer to see the data in the old location. I make heave use of profiles and I store them on an encrypted partition and I have firejail setup to give access to the old location. Whart does Firefox look at to determine whether to look in the new locations or the old location? What is the new location of profile.ini?

I just updated my browser and now I am unable to access my work profile because FF made me choose my original profile because they both use the same email. I would rather kill the original account and get back my work one. Can I do this?

Hi, I've three Browser profile, when I get new updates, no matter I at that moment be in which one of them but the update just reach one of the profiles. features like Built it VPN, weather widget and etc does not come to the others two. Please fix this one or if its a problem from me, guide me to fix it.

Title. Whenever I click the profile button on just this profile, it doesn't give me the option to switch to different profiles. This problem doesn't exist on my other profiles.

I upgraded Firefox on one of my computers and I cannot get my original profile back --- I want Fire fox my way not the way you think I want it -- How do I get my original profile back

For some reason, on my main PC (Windows 10) the icons for different profiles are not displayed over taskbar Firefox icons, while on my laptop (W11) it's properly displayed. Previously I've used Brave with multiple profiles and profile icons were properly showing on taskbar.

I'm not sure if it's related to system version or some settings, I would greatly appreciate any help as this makes it hard to work with multiple profiles open at the same time.

On the topic of profiles, I would like to suggest two handy changes: 1. separating windows on taskbar by profile would be helpful, like in Brave, where all profiles are not glued together as single row of icons on taskbar. 2. Changing browser icon by profile (the fox icon that can be changed in Appearance settings), they more larger and easier to differentiate, especially as profile icons are all white.

Hello,

I need clear instructions for completely disabling/removing Firefox's local profile system from my Firefox installation.

I want to use my Mozilla account only, without having separate Firefox profiles such as “Adina” or “Profile 1”. I do not want Firefox to create, display, or require local profiles, profile selectors, or profile-specific icons.

My current situation is:

• Firefox has created two profiles: “Adina” and “Profile 1”.
• My Mozilla account is the account I want to use.
• I want my Firefox data to remain associated with my Mozilla account.
• I do NOT want to manage separate local Firefox profiles.
• I want Firefox to behave as a single browser connected to my Mozilla account, without the new profile system.

Please tell me exactly how to disable the profile system completely, if this is possible in the current Firefox version. If it is not possible, please explain why and whether there is an official setting or supported configuration that makes Firefox use only my Mozilla account without these additional profiles.

Please do not just tell me how to switch between profiles or set one profile as default. I specifically want to disable/remove the profile system itself.

Thank you.

In "choose a profile" I have two profile and they have the same avatar. I would like to change one of the in order to differentiate them. I tried using edit but do not get a choice of avatars as I saw in a help article. What can I do?

Thank you for your help!
