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!

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 got a Firefox update recently and have not been able to access Flickr since then. I am getting a message that the page is not redirecting correctly. I am attaching the error message. I am running with standard firefox protection. I have cleared cache and cookies. I have also added Flickr as an exception to Firefox enhanced privacy tracking. Firefox is up to date (version 134.0.1 (64 bit)). Anyone else having this issue or know the solution?

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?

Hi,

I take a look to forums and docs but didn't find answer to it : just found informations about the use of firefox -P

Is there a way to change the defaults profile path.

For example, in the profiles.ini :

Name=default IsRelative=1 Path=Profiles/be7er9lz.default Default=1

this is a relative path referring to %appdata%\Mozilla\Firefox\[PathVariableValue]

Is there a way to change a config file or config to customise the path for all users a windows computer ?

For example :

setting this variable to \\nameofserver\Firefox\

will made all relatives profiles looking for : \\nameofserver\Firefox\[PathVariableValue]

without this option, I should be obliged to edit all users profiles.ini to change path to absolute

Thanks for your help

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

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?

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.

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 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 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?

I keep finding names in my account list with the name hakeem attached. I don't know who this hakeem is or how this name and the associated links became attached to my account. I have 3 firewalls and several antivirus/spam/etc blockers activated. Help.

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?

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 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

I am trying to set up a profile however when I click the account icon the profiles menu item does not show up like it says on the manage firefox profiles guide. I am updated to latest firefox version.
