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.

I don't know if it was a glitch in a recent update or something else, but every time I close a Firefox browser and then open a new one, it takes me through setting up Firefox EVERY time and changes my toolbar setting and erases my extensions. HELP!

FF 148.0, Intel Mac, current 15.7.4 (Sequoia)

In the middle of a browsing session I needed to consult my substantial browsing history and found it to be gone. I quit FF using the dropdown and restarted. After restarting FF the browsing history showed only that session and the TST sidebar with many tabs didn't display so I concluded FF created a new profile for startup but using my home page. I have the profile in use at the time (profile_a) and a month old backup of it. profile_a seems to have all the expected data and the bookmarks are correct. I've hacked around within Profile Groups and profiles.ini but FF refuses to use profile_a in spite of my edits, and worse is silent about it so I'm stuck and need help.

Possible related issue: is TST sensitive to the number of tabs? I'm a hoarder and find TST easier to use than bookmarks so had about 700 tabs stashed in TST.

I believe Firefox invited me to add another partition to my Firefox system I do not like it, finding it interferes with my normal operation of daily events and also transfers unasked from my primary partition making, for instance emails l seeking a reply.

today I tried using a link from discord to go to a site. a window I was unfamiliar with stating it was firefox told me to pick a profile. I had 2 at that point but I saw none at that point. I ignored it and did nothing. I restarted my computer later on after a file browser issue and when I tried to find my profiles and my last session I found nothing. my entire fire fox account has been wiped and I only have a single profile in my app data thats onlder than 2026. I have no idea whats happened.

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....

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.

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

While transferring data from the old profile manager system to the new one, I accidentally created one more profile than I needed. I have tried to delete the extra profile on multiple occasions, it won't go away. I have attempted to delete it through the profile management ui, and I went into the files and delete the associated data. On both occasions, the profile remained in the UI. I am unable to edit anything about the profile either. Is there anything I can do to resolve this annoyance?

I keep receiving the following pop-up. How do I get rid of it?

Pop up: This profile was last used with a newer version of this application. Please create a new profile

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.

I have a profile that I had copied from my main profile, which is connected to an email and synced. This second profile is unsynced, and it won't let me sign into my account because that account is connected to the main profile. It says I need a separate account for a separate profile. Fair enough. I try to make an account. It says I cannot sign in to the new account because the profile is synced to the old one. Very annoying to be given instructions that don't work. So, I make a new profile and sign in to my new account on it. It works. But now I don't have my bookmarks and passwords. So I find instructions on backing up my account and copy my secondary profile into the new profile with the new account. It logs me out and is now giving me the same error! (the backup was successful though) I don't want to have to copy and paste all of my passwords and things into a new account. Is there any way to make my secondary profile syncable?

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.

Hi, I am having a problem with the recently introduced Firefox profile system. In the Windows taskbar, different profiles stay grouped under the same icon. The only workaround I found is going into taskbar settings and setting it to 'Never combine,' but that causes every program to show text labels, which looks ugly. I also tried modifying taskbar.grouping.use_profile in about:config, but it didn't solve anything

New OS LMDE7 (trixie debian 13 base) Installed Firefox from the Mozilla Firefox Debian Package mozilla-debian- 1.0 Firefox 148.0

I've just installed LMDE7 alongside LMDE6 and want to move the 6 profile into 7. I've exported the 6 profile into backup and then moved it into the new Firefox Home folder (\home\...\.config\mozilla\firefox) Found both profile.in and installs.ini there AND many different profiles. (I had tried to use the profile manager and seem to have created lots of profiles beside the default-release from 7. Installs.ini shows both the original profile from the 7 install and one created with the Profile Manager and both are locked. They are also in profile.ini as installed.

So my Question is how do I install the old profile into profile.ini?
