Firefox Community Forum

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.

When I try to browse or download another copy, the error message "Your Firefox profile cannot be loaded. It may be missing or inaccessible" appears.

How do I fix this?

Thanks

When I try to login with my Firefox account to configure Sync, I get a message that says that I am logged on to a different profile and asks if I want to switch. If I switch, I get the same result with the other profile. There is only one profile folder in the Profiles directory, there are no other files or folders. What should I do?

i am unable to open a specific profile as i want its always taking me to last profile i used .I tried getting help from AI chat bots and made a short cut for a profile but at the end even its opening the last profile i opened.

I'm trying to understand Profiles, especially since I am transitioning to a new laptop.

On my older machine, I have an Original Profile. Since I've never specifically created a profile, I assume that Original Profile contains my current Settings, Bookmarks, etc. Is that a correct assumption?

My new machine also has an Original Profile. Do I need to copy my Original Profile from my older machine to the newer machine? Should I rename the profile on the new machine or leave it as Original Profile?

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.

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?

Hello! I just installed F-Fox yesterday and want to delete Google Chrome. However, my husband and I both used Chrome and I would like to add him to Firefox, so his history, passwords, etc can be imported but I don't know how to add his profile to Firefox along with mine.

Please help.

When I try to edit a profile (name, color theme), about:editprofile returns a blank page.

It was working just a few minutes ago, but stopped while I was trying to select a new theme.

I've restarted the browser a couple of times and looked at help articles but cannot figure out how to fix it.

I used Firefox this morning and it worked normal. This evening however it will not open as normal. It appears to want me to create a new profile. It does not have a toolbar or any of my bookmarks What do I need to do to restore

I did the profile thing and there's only one blank profile showing.

I did the CMD prompt -P and there is only Default showing.

This new upgrade has destroyed everything

At some point recently, a 'Profiles tab has appeared in my menu bar. Presumably this arrived during an update. I don't want it, keep accidentally clicking on it instead of bookmarks & want it gone. How do I remove it?

I already signed in with my account, but it still pop up this:"

fire fox keep pop me this: This profile was last used with a newer version of this application. Please create a new profile.

Some day not so long ago, while I was busy with something else, something happened and I was asked to choose or create a profile. Since then nothing seems to be as I am used to during several years of Mozilla Firefox use, so I want to ask where have all my bookmarks and passwords gone? If it's because of the introduction of something called AI, then please let me rely on my own I. I don't trust the "A" version!

I start the Firefox Browser from an icon on the desktop. This icon does not have a padlock symbol in the upper right corner of the icon. When the Firefox Browser starts an icon with a padlock symbol located in the upper right corner of the icon appear on the taskbar. What is the significance or the padlock symbol? What causes the padlock symbol to appear? How do I disable this option? Is this a feature added with a recent update to Firefox?
