I did the profile thing and there's only one blank profile showing.

I did the CMD prompt -P and there is only Default showing.

This new upgrade has destroyed everything

Hello I got a pop up or it was new tab informing about new firefox functions. It was about profile creation and management. Now i have two profiles and cant switch back to my old one. I cant seem to be able to delete new profile to return to my old one.

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?

Hi folks -

I've just seen the update that firefox now allows "profiles" for different purposes (e.g. work, fun, etc.) which seems really handy. But I'm trying to wrap my head around how to approach restructuring my current setup. In particular, do these profiles *all* sync with my mozilla account? Or do I need a separate mozilla account for each profile? (if so, that sort of defeats some of the utlity here unless you're sharing the PC).

I can't tell from the support article, doesn't seem to address this, but you do need to login again if you set up a new profile.

Thanks, Patrick

Hello, When I went to launch Firefox after starting up my PC this morning, I was greeted with: "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

I went right to the Mozilla forums and found the help page [https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing...] . In this article it detailed how I should go into my AppData, then Mozilla, then Firefox, and look to see where my profile.ini file is. My profile.ini file was there, alongside the installs.ini and a few other folders. I attempted also to launch the profile manager using run and the "firefox.exe -P" command, but I got the same profile error as when I tried launching the app. The help page then recommended deleting the profile.ini file and then launching Firefox to hopefully remake the default profiles.ini file and enable me to launch Firefox, so I attempted that. When I tried relaunching Firefox, the profiles.ini file did not re-appear in my Firefox folder.

I then tried deleting the Firefox folder itself, and relaunching Firefox. This resulted in it being remade, but with just 2 folders left: Crash Reports and Pending Pings. Obviously that's not ideal, so I right clicked the Firefox folder and used the Windows "Previous versions" feature to restore the Firefox folder to a backup of how it was this morning. I then re-tried launching and I still got the same missing profiles error message. I also briefly attempted manually making a new profiles.ini file with notepad, and pointing it towards my Profile withing my Profiles folder, but that still resulted in the same missing profiles error.

This is basically where I am at now. I have confirmed that I do in fact see my actual profile in my "C:\Users\****\AppData\Roaming\Mozilla\Firefox\Profiles" folder, and as far as I can tell my profiles.ini file correctly points towards it. I did another reset of my Firefox folder to a backup of where I was at this morning before attempting anything. I can confirm my Windows account (Admin, and only account on the computer) has full read and write access to all Folders and files within the Mozilla folder, although I will mention some of the files in the Firefox folder were marked with the "Read-Only" attribute (not sure if that matters, but I tried unchecking those and still no luck)

As far as I can tell I have thoroughly exhausted all the easily accessible tips on the internet for solving this, so I am wondering what to try next?

TLDR: Error: Your Firefox profile cannot be loaded. It may be missing or inaccessible" Already Attempted (And failed): -deleting and prompting a remake of the profiles.ini folder -using firefox.exe -P to launch Profile manager -deleting Firefox folder to prompt a remake of that -multiple uninstalls and reinstalls of Firefox -manually remaking profiles.ini file after it didn't come back after deletion

Will link images of (1) profiles.ini file. (2) Profiles folder.

Hi - I wanted to migrate all my changes made in the flatpak app to the aur version. I noticed the profile content has a different structure in both - aur and flatpak configs. And any attempts to replace profile content with the other resulted in browser ignoring these and initing new config files. Was wondering if my config can be ported over or thats not possible thanks.

I have been using Firefox profiles for years, long before the announcement of the new profiles UI. The new profiles UI launhed with FF 144. I'm on the latest version, which is 149.0.2 and I still don't have the new UI. Specifically, I do not see my profiles in the new UI.

When FF launches I see the new UI but my profiles are nowhere to be see as you can see in the screenshots:

https://postimg.cc/gallery/tFXz00m

I have 2 profiles and they each have their own name.

Instead I am presented with 2 option "Original Profile" and "create new Profile". When I click on orignal profile, Firefox opens my default profiles which has its own original name. However, when go throught the new UI o switch profiles, I do not see my other profile. Moreover, if I click manage profiles, I don't see either of my profiles.

The only way I am able to launch my 2nd profile is the old fashiong via "about:profiles".

Why can't I see my profiles in the new UI?

On my 2nd profile, I don't even have the new profiles UI.

Why dont't I have the new profiles UI months after you launched it?

Please help!

I made the mistake to following Mozilla's advice on why my tabs stopped coming back after I closed out, despite the fact that I had that selected in my settings. Now I'm stuck with an "Old Firefox Data" folder on my desktop and I can't remove it because I need administrator privileges -- but it's my personal PC. WTF

I opened up Firefox just now to find that my two profiles currently in use are completely inaccessible. I was faced with a "Create Profile" dialogue that launched me into a brand new profile with none of my settings, keybinds, cookies, extensions, anything. Despite this, I know for a fact that my old profiles are *still* there. As you can see my profile folders are right there, with all their data intact as far as I can tell from inspecting their contents, yet they are not accessible from the about:profiles.

Please help me. What is happening with the profile manager? How do I access those old profiles?

I have Firefox installed on both my desktop and my laptop. On my laptop, I am able to create and manage profiles; however, on my desktop, there is no option available in the menu (the hamburger menu) to do so.

I have verified that both devices are running the latest version of Firefox, which includes the profile management feature, but I am still unable to access it on my desktop.

Hello,

I am using Firefox in Malaysia. I updated with the latest browser, but I do not see the new profile management (https://blog.mozilla.org/en/firefox/profile-management/).

Is this feature available in certain countries?

Good morning, after today's FF update - right click dropdown menus are terrible! Nothing works for me... Opening new windows, new tabs, adding to bookmarks, copying, pasting, etc... How can I turn it off because I can't use it. I need to have a menu like in version 133.0.3. If I can't change it, I will have to change the browser because I can't use it! Thanks for your answer and best regards! Arthur

At startup, Firefox starts with an account setup screen. I have been using current setup for 3 years. Tried troubleshoot mode to no avail. Had same problem 3 years ago.

Hello All,

I'm using Firefox (149.0.2 snap) with LUbuntu 24.04.4 LTS. Because of a wrong graphic driver, I had to turn off hardware acceleration in FF.

When FF is started the Initial "Firefox - Choose User Profile" is unreadable (see attached : wrong_screen.jpg), but if I continue (click somewhere in the window) , all the opened tabs are readable.

Once in FF, if I want to select another profile from the application menu -> .. -> manage profiles, then the "Choose User Profile" window is fine (see attached : good_screen.jpg).

I tried to start FF with the "-P" option to specify wanted profile but it continues to start with the unreadable "Choose User Profile" window.

Could someone give me a solution, except finding the good hardware driver for my computer?

Thanks Bouilla.

This morning when I started up Firefox it had a pop-up about the new profiles feature, asking to create a new profile. Just out of curiosity I clicked the create profile button to see what the interface would look like. Since I didn't actually want to create the profile I hit the delete button, but nothing happened. So I closed the window. I then tried delete the new profile (then called "Profile 1") by hitting the trash can from the choose profiles screen. Still nothing happens. At this point my original profile window is still open, but I close everything to restart Firefox in hopes that it will allow me to delete this profile I never wanted to begin with.

The Choose profile window comes up, I select original profile and nothing happens. I can open the new "Profile 1", which I have since labelled "Bad Profile".

D:\Users\<USERNAME>\AppData\Roaming\Mozilla\Firefox\Profiles doesn't appear to have my original profile anywhere.

I'm deeply concerned this beta feature I never asked for has deleted my original profile when it should have deleted the new profile.

New OS LMDE7 (trixie debian 13 base) Installed Firefox from the Mozilla Firefox Debian Package mozilla-debian- 1.0 Firefox 148.0

I've just installed LMDE7 alongside LMDE6 and want to move the 6 profile into 7. I've exported the 6 profile into backup and then moved it into the new Firefox Home folder (\home\...\.config\mozilla\firefox) Found both profile.in and installs.ini there AND many different profiles. (I had tried to use the profile manager and seem to have created lots of profiles beside the default-release from 7. Installs.ini shows both the original profile from the 7 install and one created with the Profile Manager and both are locked. They are also in profile.ini as installed.

So my Question is how do I install the old profile into profile.ini?

I have moved my profile to a different location on the hard drive to make backups easier. How do I tell firefox where the profile is now located. c:\users\med\my data\PROFILES\mozillA\*.deFAUlt

Unimportant and mildly disruptive issue: I've been using the about:profiles method to maintain separate profiles. I am aware that this is distinct from the new way to manage profiles (about:profilemanager; https://support.mozilla.org/en-US/questions/1543697 ).

I normally use my default profile (let's call it profile A) to open other profiles (of which there are 6 + a Nightly profile).

However, recently I've noticed that if I open another profile (B) from profile A: Refreshing profile A's about:profiles makes it inactive, with the "Another copy of Firefox has made changes to profiles" error. Now, B's about:profiles correctly displays the different profiles, and I can launch more profiles from here. But A is still shown as the default profile. I've tried this with a few other profiles (C, D), but even with those open, B still seems to have the functional about:profiles page.

Is there any way to reset this, i.e. to make A's about:profiles functional even when profile B is launched?

Edit: I think this is because profile B has the new profile manager enabled, and under this, B is the original profile. I tried setting browser.profiles.enabled to false in the about:config settings but this doesn't seem to help. Oh well!

The article explaining why one should not downgrade ignores a critical reason why one needs to downgrade and that is when it turns out that the new version breaks an existing website!

I got bitten by this when Firefox "upgraded" me to V143 after which point the ticket system I use to support my customers stopped working. That same ticket system continues to work fine in Safari, Edge, Chrome and Brave, etc.

Worse, when one does try to downgrade, the old profile gets removed which means you lose EVERYTHING you had (tabs, bookmarks and presumably all the settings and saved passwords, etc). You need to be keeping the old profiles around so that they can be accessed again should someone NEED to downgrade. Fortunately I was able to use Time Machine to recover the old profile --- but somebody just didn't think this through.

Much as I have loved Firefox over the years, I'm starting to feel that it's time to give up on it and move to something else.

Turning off automatic updates is not a solution because eventually one will choose to upgrade manually and most people won't remember to make a copy of their existing profile. Should one then encounter a problem, you're back to square one

Very disappointing .
