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.

Running Windows 11. Recently there is a small gear symbol on the Firefox icon in the Taskbar. I don't want it there and it's irritating as hell. Apparently it has something to do with profile. I don't care what it has to do with, I want it to go away. I went to about:config and set browser.profiles.enabled to false, but every time I restart Firefox, it apparently gets set to true again.

There is no reason for Firefox to have forced this visual change on users. How do I make the gear go away permanently? The gear goes or Firefox gets uninstalled and I'll go back to Chrome.

HI there,

Glad you folks have included an update to the 'profiles'. However, I'm having trouble with it. I previously created two profiles using 'about:profiles' function. However, only of them has mapped on to the new profiles feature. When I try to add a profile in the new way to do it, I can only create a new one, I can't transfer a pre-existing.

See attachments. One shows the new profile manager with the 'work' profile. The second shows the 'about:profiles' with both 'work' and 'life'. How to I add 'life' to the new profile manager?

I've used Firefox as my default for years and years. Yesterday I got some popover telling me I had to create a new profile or I'd lose all my Firefox data, history, bookmarks, etc. It would not let me avoid this. So I did. Still lost all my history, started over. Today it's doing the same thing. What's up? I don't want to move to Chrome.

When i open firefox, i can choose what profile to open. I have two screens, so i was wondering if it was possible to be able to open both profiles i use, and have one on each screen. If not possible, would it be considered for an update in the future? It would make it easier, so i can have my personal profile on one screen, and my work profile on the other.

i previously set up profiles using about:profiles, but with the new profiles feature i don't see any of them showing up. i haven't found any articles that allow me to convert the files from about:profiles to use the new one.

i am not logged in to firefox on the others either.

is there a way to link the profile files on my computer to save my bookmarks and history? i don't know if there will be continued support for these files and want to make sure my bookmarks are saved for all of them. i would prefer to stay logged out of the other profiles.

Attached images include screenshots of the empty profiles (one from clicking the profiles from dropdown, one from clicking "manage profiles", and one with blacked out personal data from going to about:profiles).

I have previously made additional profiles on 'about:profiles', now Firefox has added an integrated profile manager accessible by clicking my profile on the top right. My old profiles are not available on this profile manager, but they are still available on 'about:profiles', so how can I transfer them without having to remake new ones?

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

I switched to Firefox a few months ago and I've been using the "about:profiles" page to mimic chrome's profile feature. I have 3 profiles, each with their own Mozilla account. How can I migrate these to the new profiles system?

Hi, I do not understand the new profile management feature of Firefox and how it relates to sync. I am logged into my Mozilla account that syncs bookmarks, and I use the default profile that I renamed to "personal". When I switch to a newly created "work" profile, I am no longer signed in.

Will the new profiles "personal" and "work" be synced to my account once I log on to both? I am using Firefox on several PCs and I don't want to recreate profiles such as "personal" and "work" on all the PCs manually?

Thanks for a reply.

new firefox update today plus windows update - get message "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." Have tried to restore - no luck. Other bookmarks - empty.

Lost all bookmarks

Hello,

I received a popup tab about creating separate profiles. I am still not seeing an option to create another profile, in my case keep personal and work browsing separate on my work computer. The articles I have read do not seem to fit my situation. Firefox is up to date. Thank you for your help.

Do I have to be logged into an account to use profiles? I'm on my work computer on which I don't log into my account and "Profiles" option does not show up on my toolbar.

Hello, I have two profiles, one for work and one personal. I used two different email addresses for them. How can I merge these together for the new profile management?

I don't have a Profiles menu under the Account button on the main toolbar. My Firefox was just updated and the update tab info talked about the new profiles feature as if it was available. Is this rolling out in phases or should I be seeing it?

I have version 144.0, updated on 10/14/2025.

Thanks.

I am using a very old system that is running out of storage space. There is an 8.73 GB folder that I would like to empty to free up space. C:\dtemp\Profiles contains several folders that were created 10.27.21: 2qzfs15q.default, eybandys.default, f81zrqic.default-release, pctnmazu.default-release-1, and yns5cb3s.default-release.

Can I delete any of these folders?
