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!

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?

I was interested in seeing how the profiles worked so I clicked yes to creating one, but once I set another one up I realised I would have to use a separate Mozilla account on it and I would prefer to keep everything on one browser and account. I tried to delete the profiles but it said it would delete all my bookmarks and data, is there any other way to hit undo or something and go back to the way it was before (without 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.

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 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 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).

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.

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.

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 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.

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.

After the recent update that added profiles to Firefox I have gotten them working on my personal computer but not on my work pc.

The option for creating profiles showed up once when launching the browser but I had to dismiss it at the time. Now I can't find the option to create profiles any more, I have followed the guides that mozilla have put out but the option physically is not there.

I have also tried reinstalling Firefox but that also did not work.

what do?

Thanks.

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.
