I just updated my browser and now I am unable to access my work profile because FF made me choose my original profile because they both use the same email. I would rather kill the original account and get back my work one. Can I do this?

Hello,

I need clear instructions for completely disabling/removing Firefox's local profile system from my Firefox installation.

I want to use my Mozilla account only, without having separate Firefox profiles such as “Adina” or “Profile 1”. I do not want Firefox to create, display, or require local profiles, profile selectors, or profile-specific icons.

My current situation is:

• Firefox has created two profiles: “Adina” and “Profile 1”.
• My Mozilla account is the account I want to use.
• I want my Firefox data to remain associated with my Mozilla account.
• I do NOT want to manage separate local Firefox profiles.
• I want Firefox to behave as a single browser connected to my Mozilla account, without the new profile system.

Please tell me exactly how to disable the profile system completely, if this is possible in the current Firefox version. If it is not possible, please explain why and whether there is an official setting or supported configuration that makes Firefox use only my Mozilla account without these additional profiles.

Please do not just tell me how to switch between profiles or set one profile as default. I specifically want to disable/remove the profile system itself.

Thank you.

I had two profiles set up in Firefox that are not showing up now after restarting my computer. One I have been using for YEARS. I have hundreds of bookmarked pages and saved passwords that I cannot access now. I also have a second business account that is not showing up anywhere and I need for an extremely important meeting in a half hour. This is disastrous and I do not understand why your browser did this.

I've been using Firefox for the past few months, and I've noticed a strange issue that happens occasionally when I launch the browser. It's almost like Firefox partially resets itself. My extensions are still installed, but they stooped working and their stored sign-in info like in Bitwarden or Raindrop.io is gone. I have to go into the Extensions settings, disable them, and then enable them again to get them working. For example, I use a Speed Dial extension. After one of these sudden resets, my homepage is still set to the Speed Dial page, but it just shows a blank page. I have to go to the extension settings, disable the extension, and enable it again before it works.

Some of my Firefox UI settings also revert to their defaults. For example: - The bookmarks bar, which I have set to never show, appears again. - The sidebar, which I moved to the right side, moves back to the left. - Other UI elements and customization are also reset to their default states.

I'm not entirely sure what triggers this. I think it happened once after a Firefox update, but the next time it happened there was no update involved. Has anyone experienced something similar? What could be causing this, and is there a way to prevent it from happening again?

Lost my original FF profile when I created a new 2nd profile. Opened FF. clicked profile icon. in drop down menu, I clicked on " create new profile". Set color, skipped most of the rest,then "set default browser to Firefox" using the button in FF dialog box, NOt Windows settings. Found and clicked on box " choose profile at startup". CLosed all instances of FF. Opened FF, box saying choose profile does not show my original profile, only the new one.

Help? I need to get back to my original profile, and keep the new one as choice at startup. How do I do this?

I’m honestly fed up with this issue. **How is this even acceptable?** Every time I update Firefox, or sometimes completely randomly, my entire Firefox profile gets logged out.

And it’s not just my Firefox account. **All the websites and services I’m logged into get logged out as well — including my email accounts and other websites where I have active sessions.** I then have to go through the ridiculous process of logging back into everything again.

This has happened **8 TIMES already.** Eight times! This is not a one-time bug or a minor inconvenience anymore. It is seriously disrupting my work and wasting my time.

I need to know **WHY Firefox keeps doing this** and why an ordinary browser update is apparently capable of destroying all my active login sessions. If this is a bug, it needs to be fixed. If it’s caused by a setting, update, or profile issue, then tell me exactly what is causing it and how to stop it.

I’ve used Firefox expecting it to reliably keep my profile and sessions intact. Having to repeatedly log back into my email accounts and every other website is completely unacceptable.

• • Please don’t just send me a generic “restart Firefox” or “clear your cache” response.** I’ve already dealt with this issue 8 times. I want an actual explanation and a proper solution.

Please take this seriously and investigate what is happening to my profile and login sessions.

Thanks.

When I restarted firefox on my mac, it opened up a new window with no profile/bookmarks as if I was starting firefox for the first time. It doesn't have my old profiles. I suspect there's a "hidden" version of firefox someplace that does have my profiles, but I'm not opening the right version -- which is why it is opening as if I'm starting anew. My dock often shows two firefox icons, but there are not two firefox applications in my applications folder. The only one available on the dock right now is the one that opens a blank profile. And if I open firefox from the applications folder, it also opens a blank profile.

Hi, When I click on the profile icon in the top right, I can no longer edit one of my profiles ("School"). I can still open it, bookmarks/passwords are still there, but I have to log back into everything and in the School profile, I can't switch back to "Personal" by clicking on the profile icon like normal.

I'm on Windows, and yesterday was showing something on my laptop to a mac user. They kept right clicking or something, and some tabs greyed out before I had to just close firefox. When I opened it again later using the "School" profile shortcut on my desktop, it opened a blank/new page. I was able to sign back into the account since I have sync on, so my passwords/bookmarks/etc are there, but I can't edit it any longer and can't make a new profile shortcut for my desktop. And when I open Firefox from my taskbar, it automatically opens my Personal profile instead of letting me choose which. Any ideas on what might have gone wrong & how I can fix it? Thank you!

Hello.

Has the profile logic been thought through?

When I set a default profile, I would expect

A) all new pages open into the default B) That firefox always opens the default without request.

This does not happen.

firefox.exe -P is set correctly.

Any ideas? I feel after the profile choice was improved, the basic logic may of been broken.

Thanks

TL;DR: I am dumb, but not an idiosyncratic web browser user, and it was too easy for me to accidentally permanently delete all of my browser data. Deleted profiles should be moved into system trash when deleted, not rm'd entirely.

I have never used "profiles" and somehow, after updating firefox, seemed to have created one. I have no interest in using the feature, and therefore went to delete the new profile and disable the feature. Somehow, I instead deleted the profile I had implicitly been using all along. I clicked too hastily through the warning about deleting files, because it simply did not occur to me that deleting something related to this net-new feature should clear all of my *old* data. My goal was to restore the experience I've had in firefox for years (without profiles), but because I failed to adapt to the new feature, I lost everything instead.

I apologize for maybe shouting into the void about this, but I am posting on the off chance that this will reach someone who's involved in the implementation of these features and can save some other dumb person like me from making the same dumb mistake. It's quite painful to suddenly lose years of accumulated bookmarks, extensions, history, etc. The easiest and least intrusive solution would be to always move profiles into system trash when they are deleted, and never permanently delete them.

all my icons keep wanting to sign me in i lost all n y icon mey extensions are there are enabled

enabled but not in  toolbar   ehat is going on     firefox is screwed p everytime  i hit any icons  i have to  reload or reinstall please help

I'm using the latest version of Firefox on macOS Tahoe. Over the past 2–3 days, Firefox has started behaving unexpectedly.

Issues:

   Firefox automatically creates additional Dock icons while I'm only using a single Firefox window. Even if I remove the extra icon, it reappears after some time.

   When I open a different Firefox profile, it launches under a new Dock icon instead of using the existing Firefox icon. As a result, I end up with three separate Firefox Dock icons simultaneously.

   Firefox also fails to play pronunciation audio on some dictionary websites (e.g., JapanDict). Clicking the speaker icon produces only a brief click with no spoken audio. The same pronunciation works correctly in Safari, suggesting a Firefox-specific issue.

Expected behavior:

   Firefox should use a single Dock icon (unless intentionally running separate app instances).

   Different profiles should not create unexpected duplicate Dock icons.

   Pronunciation audio should play normally, as it does in Safari.

Environment:

   macOS Tahoe (latest version)

   Firefox (latest version)

My Windows 11 PC crashed but i was able to recover copy of my firefox profile. I copied previous profile folders and i am able to access those profiles using firefox.exe -P command.

But profiles don't show up in the new profile switcher. How can i restore them to modern way profiles work.

i don't want to setup accounts and sync for my profiles.
