Firefox Community Forum

In the before times I had a default profile (for fun) and an alternative profile (for serious stuff).

Now - even with the "-p" set in the shortcuts properties I'm always asked,

OR from the taskbar it's a lottery as to which is opened.

Simple request: have the shortcut respect the "-p" it has been fed in the shortcut & Have the taskbar ALWAYS pen the DEFAULT (fun) 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.

How do i get my original profile page to always open when i open firefox instead of a new page without my bookmaks. This started right after my visit to Mozilla so i must have changed something. I don't know what!.

The last 2 days when I have shut down my computer then restarted, my Firefox profile has disappeared, along with all my bookmarks, passwords etc. I spent several hours yesterday following all the advice here to get everything back, but nothing worked. I had to create a new profile and then import an old passwords file, which I luckily had saved in Excel. This morning when I switched the computer on, the same thing has happened. I cannot even open Firefox without creating a new profile. I get a pop up box (screenshot attached), which shows no profiles, and i have to create a new one to even open Firefox. Every time I close out of Firefox and want to go back in, I am asked to choose a profile. This has never happened before.Before i give up forever on Firefox and go over to another browser, do you have any ideas how i can stop this from happening, and get my original profile, passwords, bookmarks etc back? Thanks.

It has been two times now where I will open firefox and suddenly all my profiles are gone. I have tried everything to try to get them back like trying to get "old firefox data" back or about:profiles, but there is literally nothing to recover. All of my bookmarks and passwords are fine but I have to log in to everything all over again and reset my home page with all my shortcuts. it is extremely annoying, especially when I use up all the shortcut spaces. It prompts me when I start firefox to create a profile, sign in again, and set firefox as my preferred browser. I have been using firefox for about a year and havent had this problem until a couple of weeks ago. What can i do to avoid having to do this again in the future?

First off - love Mozilla's work, thank you all for your efforts!

The problem: I f'd up with the Profiles option. I wanted to set up a Work profile on a new windows laptop associated with a new work email (msta....), and then separately have my personal profile connected to my gmail (mstn...).

Well somehow I managed to make my Work (default) profile connected to my overall Firefox + Google personal profile, and have spent a month in my ignorance saving away settings and bookmarks on this machine. Is there anyway that I can disconnect my Gmail account from the profile Work, and connect it to the secondary profile on the same machine titled 'Mel'? Or will I need to export the last month of bookmarks, implode my Mozilla install on this machine, and start over with new profiles and better practices?

Help, multipass!

Thanks, Mel

WHAT THE HELL IS MOZILLA DOING?!?! THEY KICKED ME OFF MY PROFILES AND PUT ME ON A DELETED ACCOUNT. I've been asking for one month and no one ever responded. This company is trash and wont even provide support for their mistakes. Some even replied to me making fun of my situation... The worst service I have experienced....

I got a popup when I opened a new window asking if I want to try out a build in VPN and I logged in to my Google account and after that it did a thing I wasn't expecting, it almost reset my browser but I left another Firefox window open and my data was still there and when I open Firefox my data wasn't there only my account which basally meant from guessing when I login to a Google account it created a completely new profile and mistaken it as the main one then hidden my old one to a point where I think it could get deleted if I close my old profile's window also because I checked profiles and there was only one on all the windows.

Oh and I was trying to export my browser data on the old profile but I didn't found a option, and I tried seeing what the sync feature does and I think when I actually added an account Firefox somehow changed it's mind and now thinks this is a different device or whatever because one of the things in the Connected Services says "Elbey (my username) Firefox on elbey" then another said "Firefox 149, Linux" which these two sound like my devices also because I tried out the sync feature on my old profile and needed to login and it actually worked without doing unexpected stuff which is also how I got this information.

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 recently set up an ex-Win10 PC as a Linux media player and was delighted it came with Firefox. I created a separate profile on my Win11 PC for use on the media PC. In this profile I have a few stored bookmarks, log on IDs * passwords, for sites such as BBC iplayer etc.

I did eventually manage to load it on the media PC but when I went back to my Win11 PC I couldn't find my original Firefox account. When I tried to switch accounts, it wanted to load all my original bookmarks etc and combine them in the new profile.

It's now evident that I didn't realise the difference between accounts and profiles (and I'm still somewhat confused). I can't find any clear help on how to switch between accounts and profiles. Why am I finding it so difficult? Perhaps Firefox is being too smart for me.

A windows update occurred this AM 04/15/26 and it has affected my browsing. Don't know if this update effected my G mail. My U tube profile changed form browsing to history. example: when I click on to my U tube profile it brings up the last view I was browsing. I cannot refresh Firefox like before from the help menu, of which would select the profile I desire.

Dear Sir, I am trying to set up firefox browser.I have received a notice 'your new profile is good to go' I cannot see what I should do next.Please advise. Many thanks Roger Dace

Today Firefox started acting up on YouTube. I couldn't use pause or play buttons. I rebooted my computer (though Safari works fine), I force quit Firefox and restarted it. No dice. I finally removed it from my Macbook Pro and redownloaded it. But it obviously wasn't a fresh copy because it still had all my bookmarks and extensions included. It worked for a short while and then started acting up again. I don't have any new extensions so I'm not sure what's causing the problem.

Since it seems corrupt, I don't want another copy of what I already have on my current Firefox App. I want to start over to see if it works better.

I would like to know how to do that since deleting the app and redownloading didn't give me a fresh app without all my other stuff included.

Any help would be appreciated. I found a great video addressing this but it was for Windows so I couldn't apply the info to my Mac. I checked my history but couldn't find that video which may have helped someone with Windows. Grrrr!

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).
