I'm running Firefox 122.0.1 on a Windows 10 desktop PC, with a profile which includes a userChrome.css file which makes several layout and cosmetic changes.

I also have a laptop (also Windows 10) which has an old Firefox 97.0.1 installation, and I'd like to make the same changes on this machine which I'm used to on the main computer. I copied my desktop profile to the laptop, to the same directory as its present profile, but when I rebooted Firefox the transferred profile wasn't recognised.

While doing the transfer I received error messages about some of the folders: Destination path too long. This despite the fact that the registry flag to accept extended paths is set to 1. I had to skip several folders in order to complete the transfer.

Could this be the reason why the new profile isn't being picked up? Or is it because the two Firefoxes are of different versions?

I'd be grateful for any thoughts. Many thanks.

Hi, I'm running FF 149.0 (64-bit) on Windows 11. I've used profiles for a while now and on several occassions I've "lost profiles". Currently I have three profiles which I set up and edited the icon and colour associated with each. When I launch FF I see the Profile Manager and can select any of the three and I can create a new profile which shows here. However, once in any one of the FF profiles I don't see the others - by which I mean that when I go via the hamburger lines top right and click on the current profile, the 'other profiles' section is blank. I also cannot edit the profile from using the edit pencil top right (after clicking the hamburger lines and clicking on the current profile), it takes me to about:editprofile but the page is completely blank. Confusingly, if I go to about:profiles I see two profiles, neither of which shows up in the Profile Manager! I'm going round in circles trying to understand where to edit my exisitng profiles and make sense of the five profiles that don't all show up in the same place!

I just tried creating a new profile in Nightly, and I received the "Approve sign-in to Firefox" email with a code, twice, but the profile page kept saying that my email bounced or something. Now it's saying it's locked.

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

I am currently using FF v133.0 and I want to downgrade to v130.0. I tried this once before and could not get the 'Profile' to activate and reinstall all of my settings, bookmarks, add-ons, etc.

Please provide step-by-step instructions for doing this. Any assistance will be greatly appreciated.

I am using Windows 10 64 bit.

Thank you.

I just update firefox but all my none of my bookmarks loaded. I share my computer with my husband. He has a different account on this same computer and his bookmarks are showing up on my side, but mine are nowhere to be found. Previously we have had separate bookmark lists and all was fine. I don't know where my bookmarks went.

How do I get them back and put on "my side" and still have my husband's on his side?

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.

So I have a bunch of Firefox profiles I want to set up a new profile and I want to set up the profile switching with in that profile perhaps by creating a bunch of profiles from the about profiles page and then replacing those profiles with the old ones as I don't see a way to just import old profiles in the UI. How do I go bout doing that like copy and move exactly what exactly where.

My version of Firefox wont save History, Bookmarks or Downloads. I've made sure the privacy settings are correct and have tried reinstalling Firefox several times. It also wont let me drag a link from the address bar to the bookmark bar anymore like it used to. Any help with this would be much appreciated... Thanks!

Why is my browser stating that it is managed by my organisation.

I have never used it fr work and it is my personal laptop. Please kindly provide steps to remove this

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?

Can you add a configuration setting to Mozilla Firefox to disable Create New Profile, configurable in the policies.json file? (A second option but a much uglier one would be to disable being able to select a file location for a new profile. Then you could make the default profile directory write only, which would also accomplish the same thing.) (A third option would be to able to configure extensions by default upon installation in the ExtensionSettings policy.)

To explain, I use LeechblockNG on Firefox on Ubuntu. Very helpful. By placing a policies.json file (see at bottom) in /etc/firefox/policies/ directory, I can create a system wide policy. I can make the LeechblockNG extension mandatory and to be installed upon every new profile creation. That all works very well. HOWEVER, there is NO way to be able to set those options in the new profile. So LeechblockNG is installed with default options (which are no blocking at all), which effectively bypasses the addon.

I am also writing the author of the leechblock extension to see if there is any way to set the options for leechblock upon installation (the third option above).

But I know other people have this same question, and at present, if I am correct, there is no way to block new profile creation, or the Profile Manager window in Firefox.

So could you please add that option to the Firefox policies.json configuration? Something like "DisableNewProfiles": true would do it.

Thanks!

My current policies.json file in /etc/firefox/policies/ directory: { "policies": { "BlockAboutConfig": true, "BlockAboutProfiles": true, "PrivateBrowsingModeAvailability": 1, "DisableSafeMode": true, "ExtensionSettings":{ "*": { "installation_mode": "blocked", "blocked_install_message": "Prohibited install more extensions." }, "leechblockng@proginosko.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/4374316/leechblock_ng-1.6.6.xpi" } } } }

I recently reinstalled Debian 13 on my workstation. This included installing Firefox-esr from the Debian repositories so the version before and after the reinstall is the same. Despite this, Firefox refused to start until I created a new profile - insisting that my profile was from an older version.

To add insult to injury, it offers a method to import data from Chromium (which I use rarely) but not from a previous Firefox profile.

Firefox Sync works so far as it goes, but not everyone wants to use it. Importing from a local profile should be easier to implement than remotely syncing - especially given that Firefox clients may not be the same on different devices.

And, of course, the initial point is that Firefox should accept a user profile when it was created by the same version. After all, when I upgrade Firefox on Debian, I'm not required to create a new profile. Why should I be forced to do it when I reinstall the same version?

Just this week I found it was impossible to get to firefox browsing until I chose an upsetting blob as my profile. Is there anyway to skip this step or at least to change that blob to something that makes a more pleasant experience?

Hello everyone,

I’ve been using Firefox for 5 years now and I absolutely love it. I recently bought a new laptop, but I’ve run into an issue. On my old laptop, I was able to use multiple Firefox profiles at the same time—similar to how Chrome handles profiles.

On the old setup, when I clicked the three-line (menu) button, I could see my second profile there and switch between profiles with just one click. After installing Firefox on my new laptop, I can’t find that option anymore.

I know some of you might suggest using about:profiles to switch profiles. Yes, I’m aware of that method, but I find it inconvenient because I’d have to type about:profiles every time, which is a bit of a time waste for me. I really want the same quick-switch option I had before.

How can I get that functionality back? Any help or suggestions would be greatly appreciated!

I’m already using the latest version (142.0.1, 64-bit).

Thanks

No matter what I've tried, I cannot figure out a way to edit or delete the profile from the new profile manager. Both about:editprofile and about:deleteprofile show up as a blank page (with how it looks on my normal profile for comparison). I have tried deleting the folder multiple times, but the icon still shows up in the manager and clicking it just creates a new profile with the default settings. It also does not appear when using firefox.exe -p. I had previously been using the about:profiles to manage my profiles and wanted to see if I liked the new version (I didn't), hence why I was using it in the first place.) I'm currently using Firefox version 149.0 and Windows 11 on the latest version. I have found no solution that gets rid of it. I would also be fine getting rid of the profile manager UI so it stops bothering me.

Fire Fox - This profile was last used with a newer version of this App - Create a new profile.

After logging into my account, I saw a Fire Fox page showing new features. Upon downloading Fire Fox, I saw the the above message. I didn't want a new profile, but there wasn't an option to close the window and to just continue to use the newer version that was already installed ???

I tried Control / ALT / Delete . Upon restarting it showed the same message! I uninstalled Fire Fox, which surely has not helped things.

Am I able to restore the profile from the "newer version"? Otherwise, I will probably have to setup Fire Fox from scratch and have lost all bookmarks.

Thanks so much for your assistance. Myles
