I have an issue where the following operations with the "new" profile manager don't work: - setting up a new profile (about:newprofile in the new profile is just blank) (a new profile gets created though) - deleting a profile (about:newprofile is just blank) - editing any profile that is not the original profile (about:editprofile is just blank) (works with the original profile) - the select profile interface from the account or menu button is blank when opening it from any profile that is not the original profile

What works tho is calling about:profilemanager from any profile. From there any profile can be selected and switched to.

I'm using the Bazzite (Linux distro that is Fedora based). I'm fairly new to Linux so that could be a issue, the problem was there from the get-go though and since Firefox was preinstalled I don't believe I could've messed up much.

Firefox version is 147.0.4 Bazzite version is 43.20260211.0 (Kinoite)

Reboot doesn't fix these issues. Uninstalled Firefox with deleting user data, installed it again and same behavior appears again.

I also tried installing a Firefox fork (Waterfox). It had the same issues.

I would appreciate any help and would be willing to share more detailed date if it helps somebody help me.

The attached screenshots mostly show the UI that is not working as expected.

bold text Firefox has been my browser forever. When I tried to open it this morning I was invited to create a profile, so no profile, no Firefox..... I've never had to do this before and am reluctant because of the apparent threat of losing all my passwords and bookmarks. I'm 85 years of age so don't need this complication. Any help would be appreciated, complicated high tech answer will probably be beyond me. Brian.

I have a profile that I had copied from my main profile, which is connected to an email and synced. This second profile is unsynced, and it won't let me sign into my account because that account is connected to the main profile. It says I need a separate account for a separate profile. Fair enough. I try to make an account. It says I cannot sign in to the new account because the profile is synced to the old one. Very annoying to be given instructions that don't work. So, I make a new profile and sign in to my new account on it. It works. But now I don't have my bookmarks and passwords. So I find instructions on backing up my account and copy my secondary profile into the new profile with the new account. It logs me out and is now giving me the same error! (the backup was successful though) I don't want to have to copy and paste all of my passwords and things into a new account. Is there any way to make my secondary profile syncable?

firefox on mac seems entirely broken.

in about:profiles I see 1 profile (with custom name). after restart the profile is still there, but all settings lost( Passwords, links, addons )

the same as happened before: I restarted the computer for update. than there were multiple profiles in about data. i got cunfused an in the end i deleted firefox entirely and reinstalled.

Mozilla made an update of my Firefox installation on my Win11 laptop. all my password disappeared as well as my history and bookmarks.

I have now a virgin installation and is starting from scratch.

Now I get this error message: "This profile was last used with a newer version of this application. Please create a new profile." I deleted met shortcut and I opened Firefox by using Windows search. Now I see 4 profiles! I think I do not need to create a new profile. Maybe delete 3 of them ? What to do ? And, how?

Linux User So. I recently followed a Mozilla guide, previously posted, and something that I did, or changed, I now have a very annoying "profile" name in the title bar. Further to that, I now have an additional menu option called "Profiles", with --"profile --Add Profile

Manage Profiles

I have never had or seen these items, except when I've moved my profile from an old computer to a new computer, using the console of "firefox -P" command.

It is becoming very annoying as I only have one profile, and I don't want an more.

Question. How to I block the display of 'profile information' ? Thanks

Hi,

When I opened Firefox today, it asked me which profile I'd like to use. I named one Katy and then continued. Now, I can't see any of my bookmarks, none of my passwords are saved, none of my sites recognized. I've been using Firefox for years. Everything I have is saved there. I just want my old stuff back. I'm signed in on my account, but can't see another profile that I can choose. My phone still has all the passwords and bookmarks from before but I I can't see what profile I'm signed in under. Can anyone help?

Thank you!

Katy

With the new profile manager your have to choose a Profile that you have to open on system start. That is okay, but I often change between two main profiles, "Homelab" and Personal. That means if I close Firefox and open it again it defaults to open in the last profile use. When I get an idea, I like to start researching and testing before i get side tracked

Is there a way to specify to open a link in a particular profile, like with Edge you would do something like: "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Firefox.lnk" -profile-directory="Profile 2"

Thing I have tried:

• "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Firefox.lnk" -profile-directory="Profile 2"
• C:\Users\%USER\AppData\Local\Mozilla\Firefox\Profiles\vlfrd90t.default
• "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Firefox.lnk" -P [also -profile] "[Alpha-digits].Profile 1"

Any assistance would be appreciated.

Before the new profiles update in Firefox I was using the old version of creating profiles and I want to move that profile into the new profile method. Is that possible?

I have an account for standard support release versions, I am now using extended support release version 140.7.0 and a popup notification keeps nagging me to make a new profile. How do I do this?

My power just went out for a second, now Firefox its acting like I've never used it.

I've never had this problem. Firefox has worked just fine for years. I have never had an issue with FireFox. Now I'm being told to select a profile like there isn't a set of folders with files dating back to 2021 sitting next to these fresh new folders full of files all dated to today.—I don't know shit by the way, Google told me where the profile stuff is or something idk im pissed.

How do I get Firefox to recognize the same old mountain of files its been using to store bookmarks, passwords, and all the rest is right under its stupid nose? And no the about:profiles page just gives me another blank profile to choose.

funfunfun

Good Afternoon,

I am enjoying the easier profile management with the new profile system, and I am using it currently for splitting personal / work usage. I was just wondering if it is possible to set 'Choose a profile when Firefox opens' to always apply when running a Firefox shortcut, not just when Firefox is not currently running (similar to Chrome's 'New Window' option)?

Thanks, Robert

I got a message on my Win10 PC saying, "Your Firefox profile can not be loaded. It may be missing or inaccessible."

Mozilla help suggests looking in %APPDATA%\Mozilla\Firefox\Profiles\. I did this but don't know what to do next.

I have another Win10 PC where Mozilla still works, and they do sync. Should I copy some of the Mozilla folders from it to the first PC to restore the problem? Which ones?

BTW, I can still run the Mozilla TOR Browser on the first PC. Thank you!

If I'm not mistaken, between FF146 and FF147 it appears the location of the profile directory has changed. It was:

   /home/<user>/.mozilla/firefox  

and now is

   /home/<user>/.config/mozilla/firefox

Is that correct?

As the title says, when i go to about:support, and click the open profile folder, i wanted to install a customization to allow me to edit the default tab background, but for some reason i do not have admin privileges in that folder, i can't access anything, i can't edit anything nor create a new folder, even rename it. It says that my own computer does not have admin privileges inside that folder.

today I tried using a link from discord to go to a site. a window I was unfamiliar with stating it was firefox told me to pick a profile. I had 2 at that point but I saw none at that point. I ignored it and did nothing. I restarted my computer later on after a file browser issue and when I tried to find my profiles and my last session I found nothing. my entire fire fox account has been wiped and I only have a single profile in my app data thats onlder than 2026. I have no idea whats happened.
