Firefox: форум сообщества

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

I have a question about deleting a Firefox profile. When I access the profile screen via "about:profiles," I see two profiles: "default-release" and "Default User." The "default-release" profile is fine because it displays the message "This is the active profile and cannot be deleted." But is it okay to delete the "Default User" profile? Should I also delete the files in the root directory of the C: drive and the local directory? If I delete the "Default User", will it be deleted as well?

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 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.

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

[Profile0] Name=default-release IsRelative=1 Path=Profiles/jdfj91sd.default-release-1775960183850

[Install641D10338ABA448D] Default=Profiles/abnfpged.default Default=1 IsRelative=1 Locked=1

I have not worked with the ;profiles.ini file in many years, as my FF configuration has not had problems. Thanks.

How can I transfer my bookmarks to the new version of Firefox. The bookmarks are still available from the drop-down top bar "bookmarks" but they don't show on the Firefox page. I don't know how to get to the "about:profiles" page to change back to the profile that shows my bookmarks toolbar.

I imported my profiles from another machine to a new laptop. Now the profiles all work and I can launch into them using the shortcuts with -p "[name]" this now brings up the old wizard rather than launching directly into the profile, and the new profile manager does not see them at all.

about:profiles sees them properly.

The profiles were imported by using about:profiles to make new black profiles, then copying in the data as from the support article: http://mzl.la/1xKrFsk

Many thanks in advance for the help.

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'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.

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

With the profile system, which I just used to try and fix another problem. Deleting them doesn't work I've tried manually deleting the profiles as well but they still show up in the UI and it just recreates the folder again if you try to delete it or open it. If you use the UI to try and delete it the instance and page it opens is simply blank. And now the profile I'm trying to delete isn't open. I'm trying to delete it from "original profile" and when I do it opens the a new instance of firefox with the profile I'm trying to delete with in the address bar: about:deleteprofile but the screen is empty.

Just this week firefox has been demanding that I choose a profile before I gain access. Can I skip this step? And how can I change the unpleasant blob that I must choose. I have got one answer which requests a screen shot but I can't find my question to attach it. (I can't find the old search questions--but I'm most elderly.) and need links or reminders. Anyway, I'll put the screen shot here.

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.

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 folder/subfolder, Old Firefox Data/ukn05f6l.default-release, on my desktop created 11/30/2024.

Any ideas what it is? It is huge...940mb.

Can I delete it?

Thanks

Hi all, I used to run two Firefox instances on the same computer, each one using a different account (as I mentioned in the Subject), but I don't remember how I managed this, so now that I moved to a new computer I can't reproduce it! Thanks for helping, if anyone knows. Regards, Mike

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.

I want to restore a previous profile which I can see on File Explorer, but no previous profiles appear on the About Profiles page. How can I access this previous profile?
