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Now I get this error message: "This profile was last used with a newer version of this application.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.

Hi, I am having a problem with the recently introduced Firefox profile system. In the Windows taskbar, different profiles stay grouped under the same icon. The only workaround I found is going into taskbar settings and setting it to 'Never combine,' but that causes every program to show text labels, which looks ugly. I also tried modifying taskbar.grouping.use_profile in about:config, but it didn't solve anything

I’m running into a limitation with Firefox profiles involving the original Profile Manager (about:profiles) and the new Profiles menu in the toolbar.

I previously created multiple profiles using the original Profile Manager (about:profiles), for example profiles A, B, and C. These profiles still function normally and can be launched through about:profiles, but they do not appear in the new Profiles menu in the toolbar.

I also tried using the “Copy this profile” option available from the new Profiles menu. This made it clear that the feature does not work with profiles created via about:profiles. For example, when I open profile A, I expected that I could use “Copy this profile” to copy profile A into an existing profile like profile B (which was also created using about:profiles). However, this is not possible. Profiles A, B, and C remain isolated from the new Profiles menu and cannot be accessed, copied, or managed through it.

At the moment, profiles created with the original Profile Manager (about:profiles) can only be accessed through that manager and cannot be transferred into the new Profiles menu in the toolbar.

Is there an official fix or a workaround that achieves the same result—specifically, transferring or integrating all existing profiles created with the original Profile Manager (about:profiles) into the new Profiles menu accessible from the Firefox toolbar?

I keep receiving the following pop-up. How do I get rid of it?

Pop up: This profile was last used with a newer version of this application. Please create a new profile

Just lately, Firefox has been going on about Profiles, I don't know why. I have no need for such things, yet in my Windows menu, everything says "– Original profile" at the end. All this does is make things difficult to see. How can I get rid of it, please?
