I thought original profile would save all my bookmarks, history, passwords, etc. I created a second profile for work, but that also does not contain any of my bookmarks, history, passwords, etc. I imported my bookmarks and other history/passwords from EDGE. I did this in my work profile because I couldn't get my original profile to import anything. I signed into work with my main firefox e-mail and exported bookmarks to HTML so I could upload it in my original profile. The original profile now wont log in and says I need a different e-mail account, so I'll lose everything on my original profile. It is ridiculous that my profiles don't have the same log on and don't use the same e-mail. I need someone to help me recover my system to normal working function. This has been a horrible experience and profiles are unusable.

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

[Profile1] Name=default IsRelative=1 Path=Profiles/f1jq4mlq.default

Updated to FF 150 today on Win 11 desktop.

Q1: Can I remove Profiles from the FF toolbar which is located in between Bookmarks and Tools? Only need one profile on this PC. I tried to customize the toolbar but it won't let me drag Profiles off.

Q2: For some reason my FF profile is now on C: even though I had previously moved it to D: to free up space on C: boot drive.

So I created a new profile with exact same folder name on my D: drive today.

In Profile Manager, I renamed the old profile on C: to "name.old and the new one on D: to "name.new". I set name.new as the default profile and it works properly after exiting and restarting FF.

Now I want to delete the .old profile but FF won't left me, saying Can’t delete a profile that is linked to other profiles. There are only the .old and .new profiles listed. So how do I unlink .old so I can delete all of it to free up space on C: ?

Yes, I'd like to use the same account on both of my profiles.

I understand that for some users, this may be confusing.

In my case, the only reason for different profiles is that I need to use a Proxy Server for some websites, and no proxy for other websites. Manually switching proxy settings is painful, and doing so causes traffic for my other tabs/windows to go to the proxy, which I do not want.

I have a main (set of) windows (and its tabs) going straight to the internet, then I have a separate window (and its tabs) configured to go through a proxy (SOCKS5 in this case). I want all other settings, bookmarks, passwords, etc. to be identical to both. I end up having to logout of my main profile, log into the other profile to sync settings, log out of there, and log back into my main profile.

Is there a valid technical reason why an account on the same FireFox installation cannot be shared between two profiles?

I can do this on multiple computers (same account, different computers/profile), seems odd it is restricted to not allow on the same computer.

I have an alternative solution: Install FireFox natively, then install FireFox as AUR or FlatPak, but not sure this will collide as this both uses the same profile directory. Hum...

I have a Firefox/Mozilla account associated with one email address. That is my "original profile." When I try to create a new "personal" profile, and I try to log in with a different email address, it tells me that I have to log in using the primary email for my account. But I cannot do that, because I cannot be logged in to two profiles at the same time using the same account.

How can I create a different account for a different profile? I tried doing so, but it doesn't seem to allow me.

The topic chosen is the best of a 'bad' list.

I have started using the Multiple Profiles feature in Firefox.

If I have two instances of Firefox running and I open the Bookmark Manager in both instances there is no obvious indicator as to which Firefox instance a Bookmark Manager belongs.

I have currently created a folder within the Bookmarks Menu folder that has been given the same name as the profile. Is there a better way?

Some day not so long ago, while I was busy with something else, something happened and I was asked to choose or create a profile. Since then nothing seems to be as I am used to during several years of Mozilla Firefox use, so I want to ask where have all my bookmarks and passwords gone? If it's because of the introduction of something called AI, then please let me rely on my own I. I don't trust the "A" version!

Today I got on my laptop and opened Firefox like I do every day. The browser looked different. It was an ugly purple color. A window showed me information about 'Profiles'. I didn't want any 'Profiles', I just wanted my regular Firefox Browser. So I deleted the Profiles. This also ended up deleting all of my bookmarks and passwords!! It took the last two hours and working with AI to recover my most recent backup which was two years old. Firefox hasn't been backing up any of my data that I actually need, and it actively deleted the things I rely on. Your devs and designers really messed up on this one. I bet no one uses Profiles, but everyone uses passwords and bookmarks to some degree. Why would you build it like that?! Shame, Mozilla. This was a serious error on your part. Bad product design. Make it easier to back up the things we need. Get rid of this useless 'Profiles' function that I bet no one uses.

I have used the new and old profile system, and I use Firefox Nightly. On one of my profiles I am unable to delete profiles created with the new profile system.

When I use Manage profiles and click the delete icon I get about:deleteprofile but clicking the Delete button nothing happens. The display doesn't change, no message appears in the browser console, and the profile doesn't get deleted.

This is running Firefox Nightly 153.0a1. When I use Firefox 151 on the same system (different profile) the delete works fine. When I use the same version of Firefox Nightly on a different system about:deleteprofile works fine.

Both computers are running Ubuntu 24.04.4 LTS. The new profiles don't show up in about:profiles. I now have several profiles I can't delete following the instructions from https://support.mozilla.org/en-US/kb/profile-management#w_delete-a-profile . Most of them I created, closed the window, and immediately tried to delete.

Following the instructions from https://support.mozilla.org/en-US/questions/1572980 and https://bugzilla.mozilla.org/show_bug.cgi?id=2000125#c4 I looked at the toolkit.profiles.storeID preference. The preference is the same in the child profiles as in the original profile.

I tried starting the original profile in Troubleshoot Mode. That had no effect on the behavior.

The Issue: I want to copy all bookmarks/Logins/PW from original into two additional already created but not used Profiles. Hence, I have created 3 desired profiles.

I want to copy into each profile the "Original" Bookmarks/Logins/PW nothing else matters to me, i can go to each profile and modify its settings after that and I have read the device Sync considerations.

At this stage, do I abandon the already created 2 additional Profiles and follow the Copy to New Profile procedures outlined in FAQs?

The benefit to my current state is I could copy in "Original" Bookmarks/Logins/PWs to the newly create profiles that are vacant I could then go into each profile to delete the non-relevant data.'

I have read the FAQ differences for Containers vs Profiles and still feel Profiles is best for me. I have also read Sync and the associated threads in FAQ. I have also read Copy from "Original" profile but it seems to apply when creating a Profile.

In the Original profil, I have three Bookmark sub-folders and over 200 bookmarks, plus over 480 Login/PWs. I wanted something like Profiles feature, to put my personal (PW, Bookmarks & Logins) into its own areas' Profile. The use case is Original I use for learning, Personal for banking and medical, the 3rd I have setup one Not For Profit Organization Profile. Each has relevant bookmarks/Logins.PW.

So I created my Profiles. Then realized the PW/Bookmarks/Logins are truly separated.

I'm a bit puzzled here. Initially, I tried to use the new built-in VPN for only a single domain. That doesn't work at all. Until it does, I tried to get it through other ways. Containers don't work, private windows neither, they both just inherit the global VPN setting.

So I moved on to profiles. The web found me a Mozilla support topic that suggested to open about:profiles and create a new one. Did that, opened a window for it, but couldn't get it to reopen on any easy path, just through opening about:profiles and clicking one of the many buttons again.

Then I found another description that used the "Profiles" menu. Never seen that before (probably because the menu bar isn't visible by default). Created a new profile there, too, and opened it. After restarting Firefox, all was gone! My original profile with everything was totally inaccessible, like a full data loss. Google search AI in a Chrome browser helped me out and explained what I need to do (in about:profiles, select the old one as default, then restart) to get my environment back. After that I deleted all newly created profiles and then their directories again.

Started over with a new "new" profile and continued there. Now I wanted to activate the VPN in there. It asked me to log in again, which was a good sign because finally I got a Firefox window that didn't know about the other window. But then the next failure: I couldn't log in with my credentials because that profile was already used in the other window/profile. Again, they're not completely separated from each other and there's some hidden link between them.

So, do I need a new Firefox/Mozilla account only for a separate Firefox profile? I can happily use my one account on different devices but not on the same device? Can I unlink the main profile from my account again? I don't see a logout button anywhere, I'm just logged in invisibly.
