Hi, I'm running FF 149.0 (64-bit) on Windows 11. I've used profiles for a while now and on several occassions I've "lost profiles". Currently I have three profiles which I set up and edited the icon and colour associated with each. When I launch FF I see the Profile Manager and can select any of the three and I can create a new profile which shows here. However, once in any one of the FF profiles I don't see the others - by which I mean that when I go via the hamburger lines top right and click on the current profile, the 'other profiles' section is blank. I also cannot edit the profile from using the edit pencil top right (after clicking the hamburger lines and clicking on the current profile), it takes me to about:editprofile but the page is completely blank. Confusingly, if I go to about:profiles I see two profiles, neither of which shows up in the Profile Manager! I'm going round in circles trying to understand where to edit my exisitng profiles and make sense of the five profiles that don't all show up in the same place!

Just this week I found it was impossible to get to firefox browsing until I chose an upsetting blob as my profile. Is there anyway to skip this step or at least to change that blob to something that makes a more pleasant experience?

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 am not a native English speaker, so I used translation. Please excuse any awkward phrasing. I previously updated my Firefox to version 150, but my tabs kept crashing roughly every 5 minutes. To solve this, I tried installing the Firefox ESR version. However, my profile had already been upgraded to the new version format, so ESR could not read my data. I then reinstalled version 150, but now I'm having profile issues again. I can access and launch my old profile through about:profiles, but I can't seem to save it directly as the default profile. I don't want to have to repeat this process every time I restart the browser. Is there a way to transfer all my data (bookmarks, saved passwords, add-ons, settings, etc.) to a new profile that works with the current version? Or, can I downgrade my profile so that ESR can read it? I have tried copying the files from %APPDATA%\Mozilla\Firefox\Profiles, but it didn't work after many attempts. Please help me. I really don't want to set everything up from scratch again. Thank you!

Hello everyone,

I’ve been using Firefox for 5 years now and I absolutely love it. I recently bought a new laptop, but I’ve run into an issue. On my old laptop, I was able to use multiple Firefox profiles at the same time—similar to how Chrome handles profiles.

On the old setup, when I clicked the three-line (menu) button, I could see my second profile there and switch between profiles with just one click. After installing Firefox on my new laptop, I can’t find that option anymore.

I know some of you might suggest using about:profiles to switch profiles. Yes, I’m aware of that method, but I find it inconvenient because I’d have to type about:profiles every time, which is a bit of a time waste for me. I really want the same quick-switch option I had before.

How can I get that functionality back? Any help or suggestions would be greatly appreciated!

I’m already using the latest version (142.0.1, 64-bit).

Thanks

I made the mistake to following Mozilla's advice on why my tabs stopped coming back after I closed out, despite the fact that I had that selected in my settings. Now I'm stuck with an "Old Firefox Data" folder on my desktop and I can't remove it because I need administrator privileges -- but it's my personal PC. WTF

This afternoon, I clicked on a link from an email and for the first time got a choose a profile pop-up. I do not want this; I have read info on Mozilla and elsewhere about its purpose but it doesn't say how to just stop the pop-up - there should be an option just stop the pop-up because I don;t want to have to choose amongst options. I have started copy-pasting the links in emails and going to Chrome and will seriously have to reconsider using Firefox of this continues. I don't want to have to type about:config or anything - this should have been an opt out or opt in thing and I want out. Thank you for your help.

No matter what I've tried, I cannot figure out a way to edit or delete the profile from the new profile manager. Both about:editprofile and about:deleteprofile show up as a blank page (with how it looks on my normal profile for comparison). I have tried deleting the folder multiple times, but the icon still shows up in the manager and clicking it just creates a new profile with the default settings. It also does not appear when using firefox.exe -p. I had previously been using the about:profiles to manage my profiles and wanted to see if I liked the new version (I didn't), hence why I was using it in the first place.) I'm currently using Firefox version 149.0 and Windows 11 on the latest version. I have found no solution that gets rid of it. I would also be fine getting rid of the profile manager UI so it stops bothering me.

With the profile system, which I just used to try and fix another problem. Deleting them doesn't work I've tried manually deleting the profiles as well but they still show up in the UI and it just recreates the folder again if you try to delete it or open it. If you use the UI to try and delete it the instance and page it opens is simply blank. And now the profile I'm trying to delete isn't open. I'm trying to delete it from "original profile" and when I do it opens the a new instance of firefox with the profile I'm trying to delete with in the address bar: about:deleteprofile but the screen is empty.

Hi - Firefox placed an 'Old Firefox data' folder on my desktop and I am unable to delete it. I'ver tried third party apps, logging in as administrator, command line delete, uninstalling FF but am still stuck with it and my network settings are wrecked so I can't re-establish connection to the internet on that machine. Anyone with any suggestions as to how I get rid of the 'Old Firtefox data' folder ? Many thanks...

Mozilla made an update of my Firefox installation on my Win11 laptop. all my password disappeared as well as my history and bookmarks.

I have now a virgin installation and is starting from scratch.

Now I get this error message: "This profile was last used with a newer version of this application. Please create a new profile." I deleted met shortcut and I opened Firefox by using Windows search. Now I see 4 profiles! I think I do not need to create a new profile. Maybe delete 3 of them ? What to do ? And, how?

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.

Hi,

My Firefox had auto updated to the newer version with AI built-in and auto-enabled, which meant the browser would crash EVERY. SINGLE. TIME. I would launch it.

For perspective, I am running an old Lenovo Thinkcentre mini PC with an Intel i5 6th gen and 16gb of ram; its got Windows 11 installed, and always running out of memory with the simple things like browsing and word processing. This is NOT a PC or use-case that needs or warrants AI.

So, I uninstalled Firefox (149) and installed the latest version WITHOUT AI built-in (147).

I then synced my profile, and things ran fine. An hour passed, and then i kept getting an error, saying my profile was created with whatever and I need to create a new profile.

So, I created a new profile and synced, again, and I got the error, AGAIN...

I'm about to boycott Firefox on all the devices I control, and opt for an older version of Opera or something more obscure, so that I don't have to deal with this nonsense.

In "manage profiles" I see where to delete the extra profile that was created and I don't want. Thanks to Cetaseus1. my question is does deleting a profile delete all the bookmarks? there is an info box that warns that bookmarks will be deleted including my 30,000+ bookmarks that were rolled over to this unwanted profile that just appeared. My intent is to have one remaining profile and all my bookmarks. I am hesitant to delete a profile and loose all those bookmarks. I won't delete until Mozilla assures me that I won't lose the bookmarks in the other profile. Thanks.

With the new update came profiles, which is pretty useless for me. However, it bugs me that the firefox icon on the taskbar now has the profiles' star on it. Is there a way to remove this?

bold text Firefox has been my browser forever. When I tried to open it this morning I was invited to create a profile, so no profile, no Firefox..... I've never had to do this before and am reluctant because of the apparent threat of losing all my passwords and bookmarks. I'm 85 years of age so don't need this complication. Any help would be appreciated, complicated high tech answer will probably be beyond me. Brian.

I want to restore a previous profile which I can see on File Explorer, but no previous profiles appear on the About Profiles page. How can I access this previous profile?

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?
