Firefox Community Forum

I'm a Chinese firefox user, so the following descriptions are translated and may not be so accurate. And the attached image is also Chinese, if necessary please use a translation app or somewhat to see it. I have only one default profile in my Firefox account, and I have stored a large number of passwords and bookmarks in this default profile. For certain reasons, I signed out of this profile while retaining the local data such as passwords—meaning that, apart from not being logged in, my browser state remains exactly the same as before. Now I wish to sign back in to enable synchronization. I can see a "Sync and Save Data" button prompting me to log in. After clicking this button, I am asked to enter my username and password, but then I receive a message stating that I have reached the account limit for this profile, and that this profile was previously synced to another account. This is absurd, as I do not have another account, nor have I ever synced this profile to any so-called other account. As a result, I am unable to sign in on this current profile.

Updated to FF 150 today on Win 11 desktop.

Q1: Can I remove Profiles from the FF toolbar which is located in between Bookmarks and Tools? Only need one profile on this PC. I tried to customize the toolbar but it won't let me drag Profiles off.

Q2: For some reason my FF profile is now on C: even though I had previously moved it to D: to free up space on C: boot drive.

So I created a new profile with exact same folder name on my D: drive today.

In Profile Manager, I renamed the old profile on C: to "name.old and the new one on D: to "name.new". I set name.new as the default profile and it works properly after exiting and restarting FF.

Now I want to delete the .old profile but FF won't left me, saying Can’t delete a profile that is linked to other profiles. There are only the .old and .new profiles listed. So how do I unlink .old so I can delete all of it to free up space on C: ?

Yes, I'd like to use the same account on both of my profiles.

I understand that for some users, this may be confusing.

In my case, the only reason for different profiles is that I need to use a Proxy Server for some websites, and no proxy for other websites. Manually switching proxy settings is painful, and doing so causes traffic for my other tabs/windows to go to the proxy, which I do not want.

I have a main (set of) windows (and its tabs) going straight to the internet, then I have a separate window (and its tabs) configured to go through a proxy (SOCKS5 in this case). I want all other settings, bookmarks, passwords, etc. to be identical to both. I end up having to logout of my main profile, log into the other profile to sync settings, log out of there, and log back into my main profile.

Is there a valid technical reason why an account on the same FireFox installation cannot be shared between two profiles?

I can do this on multiple computers (same account, different computers/profile), seems odd it is restricted to not allow on the same computer.

I have an alternative solution: Install FireFox natively, then install FireFox as AUR or FlatPak, but not sure this will collide as this both uses the same profile directory. Hum...

Здравствуйте, на одном из компьютеров которыми я пользуюсь браузер выдаёт всплывающее окно со следующим текстом " this profile was last used with anewer version of this application. Please create a new profile." скрин прилагаю. на всех компьютерах win10, с чем это может быть связано?

I have a Firefox/Mozilla account associated with one email address. That is my "original profile." When I try to create a new "personal" profile, and I try to log in with a different email address, it tells me that I have to log in using the primary email for my account. But I cannot do that, because I cannot be logged in to two profiles at the same time using the same account.

How can I create a different account for a different profile? I tried doing so, but it doesn't seem to allow me.

At some point recently, a 'Profiles tab has appeared in my menu bar. Presumably this arrived during an update. I don't want it, keep accidentally clicking on it instead of bookmarks & want it gone. How do I remove it?

I recently installed firefox on my Windows 10 laptop, but i cant pin it to the taskbar via right click (this bug wont go away no matter what i do) and also cant open the start menu (also wont go away). I also tried to pin it directly via the exe, but for some reason, it opens another version of firefox, almost as if it was in another acount was logged in (i only have 1 account in firefox).

The topic chosen is the best of a 'bad' list.

I have started using the Multiple Profiles feature in Firefox.

If I have two instances of Firefox running and I open the Bookmark Manager in both instances there is no obvious indicator as to which Firefox instance a Bookmark Manager belongs.

I have currently created a folder within the Bookmarks Menu folder that has been given the same name as the profile. Is there a better way?

Some day not so long ago, while I was busy with something else, something happened and I was asked to choose or create a profile. Since then nothing seems to be as I am used to during several years of Mozilla Firefox use, so I want to ask where have all my bookmarks and passwords gone? If it's because of the introduction of something called AI, then please let me rely on my own I. I don't trust the "A" version!

when i am in my browser how can i tell which email account this is for. i have two profiles each with a different email account, i want to able to see which one my current browser is tied to.

Today I got on my laptop and opened Firefox like I do every day. The browser looked different. It was an ugly purple color. A window showed me information about 'Profiles'. I didn't want any 'Profiles', I just wanted my regular Firefox Browser. So I deleted the Profiles. This also ended up deleting all of my bookmarks and passwords!! It took the last two hours and working with AI to recover my most recent backup which was two years old. Firefox hasn't been backing up any of my data that I actually need, and it actively deleted the things I rely on. Your devs and designers really messed up on this one. I bet no one uses Profiles, but everyone uses passwords and bookmarks to some degree. Why would you build it like that?! Shame, Mozilla. This was a serious error on your part. Bad product design. Make it easier to back up the things we need. Get rid of this useless 'Profiles' function that I bet no one uses.

I already signed in with my account, but it still pop up this:"

fire fox keep pop me this: This profile was last used with a newer version of this application. Please create a new profile.

How do I change a profile folder's name without causing any problems? I'm on a Mac.

I know I can change a profile's name for internal Firefox use (by going to about:profiles in the URL address section of the browser), but the cryptic folder names remain the same. I've read that you should never change a profile folder's name directly (inside ~/Library/Application Support/Firefox/Profiles/), so is there another way?

I run both the standard version of Firefox and the developer edition on the same computer, so it would be nice to immediately see which profile folder belongs to which Firefox version by their names.

When I click on a link in outlook recently, I have been getting an seperate firefox pop up but it has none of my passwords. How do i set up to have all the info as the regular firefox browser I use.

I have used the new and old profile system, and I use Firefox Nightly. On one of my profiles I am unable to delete profiles created with the new profile system.

When I use Manage profiles and click the delete icon I get about:deleteprofile but clicking the Delete button nothing happens. The display doesn't change, no message appears in the browser console, and the profile doesn't get deleted.

This is running Firefox Nightly 153.0a1. When I use Firefox 151 on the same system (different profile) the delete works fine. When I use the same version of Firefox Nightly on a different system about:deleteprofile works fine.

Both computers are running Ubuntu 24.04.4 LTS. The new profiles don't show up in about:profiles. I now have several profiles I can't delete following the instructions from https://support.mozilla.org/en-US/kb/profile-management#w_delete-a-profile . Most of them I created, closed the window, and immediately tried to delete.

Following the instructions from https://support.mozilla.org/en-US/questions/1572980 and https://bugzilla.mozilla.org/show_bug.cgi?id=2000125#c4 I looked at the toolkit.profiles.storeID preference. The preference is the same in the child profiles as in the original profile.

I tried starting the original profile in Troubleshoot Mode. That had no effect on the behavior.

You guys did an update that now makes me choose a profile every time I log in. WHY? Keep it simple. I tried to go into Profile and keep it simple. Can you tell me how to go back to reset the old way?

Sometimes, you should leave well enough alone. Right????? HMMMMM???

All I want to do is open Firefox and go to my default page. Okay?

I will wait for your response.
