Why do I continue to receive a message from Firefox after creating a New Profile?

Firefox This profile was last used with a newer version of this application. Please create a new profile. OK

A new profile PERSONAL #2 was created following the Steps to Create a New Firefox Profile.

What did I do wrong? how to correct, so that I stop receiving the error message?

TL;DR: I am dumb, but not an idiosyncratic web browser user, and it was too easy for me to accidentally permanently delete all of my browser data. Deleted profiles should be moved into system trash when deleted, not rm'd entirely.

I have never used "profiles" and somehow, after updating firefox, seemed to have created one. I have no interest in using the feature, and therefore went to delete the new profile and disable the feature. Somehow, I instead deleted the profile I had implicitly been using all along. I clicked too hastily through the warning about deleting files, because it simply did not occur to me that deleting something related to this net-new feature should clear all of my *old* data. My goal was to restore the experience I've had in firefox for years (without profiles), but because I failed to adapt to the new feature, I lost everything instead.

I apologize for maybe shouting into the void about this, but I am posting on the off chance that this will reach someone who's involved in the implementation of these features and can save some other dumb person like me from making the same dumb mistake. It's quite painful to suddenly lose years of accumulated bookmarks, extensions, history, etc. The easiest and least intrusive solution would be to always move profiles into system trash when they are deleted, and never permanently delete them.

I have been using the old firefox profiles system for ages. However, whenever I open my browser (in one of about 5 profiles), I always get this pop-up saying "Say hello to Firefox profiles". It is incredibly annoying and turning me off Firefox completely! Can somebody tell me how to turn this message off? I assume it's in the settings somewhere.

I created a new profile on my account. Whenever I am in the original profile, I can click on the new profile and it will open a new window with a new icon. However, I notice that under the new profile, it is not signed in. When I try to sign in, I get an error that says

Account already in use xxx@gmail.com is already signed in to the “original” profile

You can only associate this account with one profile on this computer.

Then it forces me to switch back to the original profile. This tells me that the profile is not syncing for access across devices.

This is happening on my macbook.

Been using Firefox for 20+years in poway, ca now in Oregon City, somehow I ended up with 3 profiles, I would like to merge at least the bookmarks and delete 2 To stop confusion, thanks Ralph Kirn

Hello All,

I'm using Firefox (149.0.2 snap) with LUbuntu 24.04.4 LTS. Because of a wrong graphic driver, I had to turn off hardware acceleration in FF.

When FF is started the Initial "Firefox - Choose User Profile" is unreadable (see attached : wrong_screen.jpg), but if I continue (click somewhere in the window) , all the opened tabs are readable.

Once in FF, if I want to select another profile from the application menu -> .. -> manage profiles, then the "Choose User Profile" window is fine (see attached : good_screen.jpg).

I tried to start FF with the "-P" option to specify wanted profile but it continues to start with the unreadable "Choose User Profile" window.

Could someone give me a solution, except finding the good hardware driver for my computer?

Thanks Bouilla.

First, I have very limited understanding of software. I need very simple explanations.

Here's my issue. I use Thunderbird on my desktop computer. I have used the Import/Export > Options > Backup Scheduling function to backup my Thunderbird email to my USB/flash drive. I have labelled the backup folder on my flash drive "Thunderbird email backup." That folder contains numerous subfolders including: 1) calendar-data 2) chrome_debugger_profile 3) crashes 4) datareporting 5) extensions 6) ExternalMailFolders 7) Mail 8) minidumps 9) saved-telemetry-pings 10) scheduled-notifications 11) settings 12) shader-cache 13) storage.

Again, these are the subfolders created/named by the Thunderbird Import/Export backup. I HAVE NO IDEA WHAT THESE FOLDERS MEAN.

Here's what I want - it's actually very simple. I want to be able to see (read) my backed up email on my flash drive without using the Thunderbird installed on my computer. I want complete interaction with the backed up email without my desktop Thunderbird - or my online email account - being involved at all.

My understanding is that Thunderbird Portable is supposed to be able to allow me to do that. I downloaded Thunderbird Portable (from https://portableapps.com) to my flash drive but when I tried to access it the first thing it did was try to force me to put in my online account (POP?) information.

I don't want to do that. I just want to open Thunderbird Portable on the flash drive and have it realize that all of my backed up Thunderbird email information is right there in the same flash drive. I want it to just access and use what's right there.

I was really hoping that Thunderbird Portable would simply ask me where to look - in a very user-friendly way! - and I could tell it to go to my "Thunderbird email backup" folder on my flash drive (WHERE ALL MY THUNDERBIRD INFO IS!) and it would simply do just that and provide me with complete Thunderbird service for the backed up email.

Am I missing something? Can someone give me a VERY SIMPLE walk through to do what I would think should be a very simple thing? Thank you. Chris (6/29/26)

PS - I've read the Mozilla Support ARTICLE: Thunderbird Portable (Mozilla Thunderbird, Portable Edition) and other portable apps as alternatives (https://support.mozilla.org/en-US/questions/1285834) and it alludes in general terms to exactly what I want to do but it does not give any step-wise instructions.

Recently a tiny icon of an empty shopping cart has been superimposed at the top right-hand corner of the Firefox icon in my system tray. I want to get rid of it. In addition, just in the last few days, I'm being asked to choose among profiles when I sign onto Firefox and I want to have only one default profile and to avoid that extra step in signing on.

Much to my regret, I clicked on New Profile, and now all my shortcuts are gone. How to I go back???? Or, I suppose I could find out how to add shortcuts. But, just so you know, I am ANGRY that I am wasting time on this! Why couldn't you have left well enough alone????

Suddenly I have to click passed something called a profile screen. Don't want it. totally useless. Absolutely annoying. I never want to see it again. How do I do that?

After closing Firefox, I often get a message for "creating a new profile". It seems difficult to do this and it would be very helpful to have a link where this can be easily done. Thanks for all your help. Alok Bhargava [edited email from community support forum]

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.

Out of nowhere today I encountered with Firefox seemingly crashing. My laptop said it needed to reboot. Once rebooted I began to get the missing/inaccessible profile error. I tried to uninstall / reinstall but continue to get the error. When I search through for the missing profile per all guidance and troubleshooting Windows says it's not found. When I use the "run" it doesn't bring me to a folder but to a notepad type screen (copy paste below). I do not see where I have any options. Would it be effective to just delete all Mozilla from my laptop? I uninstalled / reinstalled but same error.

is there any way to perform a dynamic backup of Thunderbird. By that I mean a regular (e.g. daily) backup of the profile or at least the mailboxes using a scheduler without closing Thunderbird down?

I'm getting frequent popup messages from McAfee, my email threat detector, that they've detected and stopped a threat, but none is identified. McAfee's chatbot wants me to create a new profile and add my email accounts to that profile. Will I lose access to all my currently saved email messages and calendar information?

I really don't need a profile in Firefox and if I delete the profiles listed, you will wipe out all my bookmarks/settings. Why do I need to see a yellow triangle on the Firefox app icon?
