Firefox Community Forum

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]

Help! I updated my account to a new email months ago. I have been trying to set up a new different profile. Copying a profile or trying to add a profile adds the newly made profile to my old email address instead of my new email address. In the new profiles created, I am unable to login to my new email and password.

I have a problem with the browser automatically starting when I start my PC. I have this feature disabled (!) ("Open Firefox automatically when your computer starts up" turned OFF) Everything was fine, but then I started using the "profiles" feature - browser start's to open automatically when i start up my pc.

when I created a new profile (in addition to the main one). The problem appeared, and that was a long time ago (at least half of year ago it was already as now). I hoped that it would be fixed and didn't write to support. Windows and the browser itself have been updated several times since then - this did not help.

Changing the settings in different profiles, creating / deleting them, and other basic actions did not help. What happens is that the browser ALWAYS opens when I start the PC (Profile selection tab, i have turned ON "Select profile when Firefox start up")

I tried turn off \ delete all plugins, turn on\turn off almost every default setting, no effect. What should i do?

Browser version - 150.0 (64-bit) (from "settings-about firefox") Windows 11 Pro 25H2

Currently have 4 profiles in Firefox - but problem appeared after creation on 2nd profile. "Open Firefox automatically when your computer starts up" turned off in every profile.

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.

Hi! I love Firefox, but on updates when my account signs out. I also lose all my Firefox profiles. Even when I sign in again, and sync everything on my Firefox account, I lose my primary and secondary profiles. Whilst it restores my bookmarks and extensions on my account. I lose my bookmarks etc. on my secondary profile.

I'm using FF on both Windows 11 and android, but this problem only effects Windows 11.

Cheers :)

new firefox update today plus windows update - get message "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." Have tried to restore - no luck. Other bookmarks - empty.

Lost all bookmarks

Hi all, I used to run two Firefox instances on the same computer, each one using a different account (as I mentioned in the Subject), but I don't remember how I managed this, so now that I moved to a new computer I can't reproduce it! Thanks for helping, if anyone knows. Regards, Mike

Pinterest has been slow to load for the past month. Now it will not load at all. It works fine in safe mode. A fresh install of Firefox did not help anything? I see other folks are having the same problem. Amazon and Facebook are now doing the same thing in Firefox. These 3 programs work without issue in Chrome Brave and Edge. Any one have a fix?

Thanks, Wayne
