Firefox Community Forum

Once again the latest firefox browser has issues so I rolled back the last stable version. It keeps prompting me to create a new profile. I want to use the previous profile that has all my setting and bookmarks. I got to about:profiles and selected the profile i want to make default and it will not add it to firefox. How can I do this?

At first deployment of multiple profiles in early 2026, my use was really intuitive and I was able to understand the FAQ and Community notes. Early October, the releases started to implement some refinements. I am not understanding these refinements and while I am seeing the error message (attached), I am not understanding what the fix is to use my additional profiles (two), int the past month, I have not found a way to get to my two additional profiles.

My environment: Windows 11 Pro - Firefox 158.0 (64 bit) I have Profiles "Original" and two others. I have one single Mozilla account. I copied my two profiles from original and had made great progress culling the profile passwords and bookmarks, I have only been syncing my original profile two my two cellphones. 95% of my use is from desktop Firefox.

Attached is a well documented result error but I am not locating how to get to the profiles I had created from the attached error message.

Every time there is an update, Firefox creates a new profile and hides all passwords etc. It is therefore impossible to work with it now. With 157 I now have a worthless Firefox, because all links, passwords, settings etc have been cleared and a new profile has been created.

On linux, in the past, firefox kept all its data in home/{user}/.mozilla. This was changed at some pont to spread the data out into /home/{user}/.config, /home/{user}/.cache and maybe another place but when the change was made existing data was not moved and remained in /home/{user}/.mozilla. For my purposes I prefer to see the data in the old location. I make heave use of profiles and I store them on an encrypted partition and I have firejail setup to give access to the old location. Whart does Firefox look at to determine whether to look in the new locations or the old location? What is the new location of profile.ini?

I just updated my browser and now I am unable to access my work profile because FF made me choose my original profile because they both use the same email. I would rather kill the original account and get back my work one. Can I do this?

Hi, I've three Browser profile, when I get new updates, no matter I at that moment be in which one of them but the update just reach one of the profiles. features like Built it VPN, weather widget and etc does not come to the others two. Please fix this one or if its a problem from me, guide me to fix it.

Title. Whenever I click the profile button on just this profile, it doesn't give me the option to switch to different profiles. This problem doesn't exist on my other profiles.

I upgraded Firefox on one of my computers and I cannot get my original profile back --- I want Fire fox my way not the way you think I want it -- How do I get my original profile back

For some reason, on my main PC (Windows 10) the icons for different profiles are not displayed over taskbar Firefox icons, while on my laptop (W11) it's properly displayed. Previously I've used Brave with multiple profiles and profile icons were properly showing on taskbar.

I'm not sure if it's related to system version or some settings, I would greatly appreciate any help as this makes it hard to work with multiple profiles open at the same time.

On the topic of profiles, I would like to suggest two handy changes: 1. separating windows on taskbar by profile would be helpful, like in Brave, where all profiles are not glued together as single row of icons on taskbar. 2. Changing browser icon by profile (the fox icon that can be changed in Appearance settings), they more larger and easier to differentiate, especially as profile icons are all white.

Hello,

I need clear instructions for completely disabling/removing Firefox's local profile system from my Firefox installation.

I want to use my Mozilla account only, without having separate Firefox profiles such as “Adina” or “Profile 1”. I do not want Firefox to create, display, or require local profiles, profile selectors, or profile-specific icons.

My current situation is:

• Firefox has created two profiles: “Adina” and “Profile 1”.
• My Mozilla account is the account I want to use.
• I want my Firefox data to remain associated with my Mozilla account.
• I do NOT want to manage separate local Firefox profiles.
• I want Firefox to behave as a single browser connected to my Mozilla account, without the new profile system.

Please tell me exactly how to disable the profile system completely, if this is possible in the current Firefox version. If it is not possible, please explain why and whether there is an official setting or supported configuration that makes Firefox use only my Mozilla account without these additional profiles.

Please do not just tell me how to switch between profiles or set one profile as default. I specifically want to disable/remove the profile system itself.

Thank you.

In "choose a profile" I have two profile and they have the same avatar. I would like to change one of the in order to differentiate them. I tried using edit but do not get a choice of avatars as I saw in a help article. What can I do?

Thank you for your help!

When I try to open a link to an app or program from my Outlook account I get two tabs trying to open the same page. Big load time error. I believe this may be due to having two Mozilla/Firefox accounts and both are trying to open that link. I need to learn how to close one account to keep one open and able to access excess links. I'm open to any reasonable solution that leave me with my history and account info.

I had two profiles set up in Firefox that are not showing up now after restarting my computer. One I have been using for YEARS. I have hundreds of bookmarked pages and saved passwords that I cannot access now. I also have a second business account that is not showing up anywhere and I need for an extremely important meeting in a half hour. This is disastrous and I do not understand why your browser did this.

My bank had me reinstall firefox. NOW I keep getting messages to create a new user because it shows I have previously logged in on a more recent version. I had used a version of 60 something and now I have something in the 40's (140.16.0 .Windows 11) I really hesitate to change users because I do not have a clear picture of what I will lose. Like bookmarks and saved stuff.

I would like to just stop the messages.
