Hello, I have installed the latest Firefox on my Windows 11 desktop PC. I have created a shortcut to Firefox in the start menue Since a few week, I observed that I had to invoce Firefox twice in order to get is running once. The same happens if I double-click on firefox.exe in the intallation folder (C:\Program Files\Mozilla Firefox): After the first double-click, the windows activity circle appears for a few seconds and then dissapears again (without staring Firefox). After the second double-click, Firefox starts immediately.

I can repeat this several times.

• first double click > nothing happens
• second double click > Firefox starts
• closing Firefox
• third double click > nothing happens
• fourth double click > Firefox starts
• closing Firefox
• fifth/seventh/... double click > nothing happens
• sixth/eigth/.. double click > Firefox starts

I have no idea what might have gone wrong. Any suggestion from the community is appreciated. Best,

This problem just started with the latest version of Firefox that opens with two profiles. It worked for a short time and then failed. Firefox will not open if I choose the default profile. I can open Firefox if I choose Profile #2, but it has none of the history of the default profile. I lose all of my extensions, history, bookmarks - everything.

How can I get back to where I was yesterday? (Note: I'm just a user, not a computer geek, and don't understand the buzzwords or technospeak. I can follow clear instructions like copy, delete, rename, etc.)

I'm using an HP laptop with Windows 11.

Application error: a client-side exception has occurred while loading (see the browser console for more information).

where is the browser console? how do i fix it never had an issue with until the last two days?

Hi

I have tried to launch Firefox a number of times today and every time it has frozen and does not respond. When trying to select the option of opening the software in Troubleshoot mode, once again the software freezes and I am unable to open the software in Troubleshoot mode . I have tried shutting and re-opening both the software and my laptop but this does not resolve the issue. Can you please either resolve the issue of the software freezing or tell me how I can resolve the issue.

I always use Firefox Private Window when I go on the Internet. Today, while I was on Fidelity.com, I was suddenly logged out. When I tried to go back to Fidelity.com using Firefox/Private Window, a dialog box on Microsoft Edge appeared asking me to: "Choice: #1 Do you want to make Firefox to be your default" "Choice: #2 Not Now". Which ever I choice I choose, Microsoft Edge will appear with the two above choices. This has been happening repeatedly for several minutes now, so I tried to reach Firefox Support.

My main problem is I cannot access Firefox / Private Window anymore since I was suddenly logged out of Fidelity.com.

Would you please fix this problem. Also, I already selected Firefox to be my default browser long time ago. Why am I being this question every time I go on the internet using Firefox?

After installing Firefox on a new Windows 11 computer, when I click on the Desktop icon, a Firefox window opens but it doesn't open previous Tabs and the Application menus does not work. I can open new Tabs though and it downloads websites. If I click on the Firefox icon on the Windows Taskbar, Firefox operates normally.

Why doesn't the Desktop icon start Firefox so it works correctly?

Thanks

Here is what the message says: "Firefox is trying to install a new helper tool. Enter your password to allow this" I tried to install but Firefox won't open. Firefox icon just bounces around, I have to force quit to stop it. I DO NOT WANT THIS TOOL BUT I WANT TO USE FIREFOX. By the way this is sent from my other user, as the problem is on my admin. user and I can't open Firefox to do anything!

ich habe probleme firefox zu starten wenn ich den browser öffnen will erscheint die meldung das firefox nicht geöffnet werden kann weil er noch geöffnet ist obwohl er aber geschlossen ist ich habe schon versucht den laptop neuzustarten und Firefox neu zu installieren es kam immer die selbe meldung der laptop verwendet Windows 7

Firefox tab crashes whenever I try to open Firefox. I have AOL and Firefox browser. I've tried the close and reload, restart laptop, and redownloading Firefox to no avail. However, I was able to open my AOL and email. I reached this help page using Edge.

Whenever I click on the Firefox icon to start, instead of FF, AOL comes up. I looked on my C: program list and it is not listed so I can't delete it. It just started doing this in the last week. I tried downloading FF again with no luck. Its on an old windows 10 machine.

Hello, When I went to launch Firefox after starting up my PC this morning, I was greeted with: "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

I went right to the Mozilla forums and found the help page [https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing...] . In this article it detailed how I should go into my AppData, then Mozilla, then Firefox, and look to see where my profile.ini file is. My profile.ini file was there, alongside the installs.ini and a few other folders. I attempted also to launch the profile manager using run and the "firefox.exe -P" command, but I got the same profile error as when I tried launching the app. The help page then recommended deleting the profile.ini file and then launching Firefox to hopefully remake the default profiles.ini file and enable me to launch Firefox, so I attempted that. When I tried relaunching Firefox, the profiles.ini file did not re-appear in my Firefox folder.

I then tried deleting the Firefox folder itself, and relaunching Firefox. This resulted in it being remade, but with just 2 folders left: Crash Reports and Pending Pings. Obviously that's not ideal, so I right clicked the Firefox folder and used the Windows "Previous versions" feature to restore the Firefox folder to a backup of how it was this morning. I then re-tried launching and I still got the same missing profiles error message. I also briefly attempted manually making a new profiles.ini file with notepad, and pointing it towards my Profile withing my Profiles folder, but that still resulted in the same missing profiles error.

This is basically where I am at now. I have confirmed that I do in fact see my actual profile in my "C:\Users\****\AppData\Roaming\Mozilla\Firefox\Profiles" folder, and as far as I can tell my profiles.ini file correctly points towards it. I did another reset of my Firefox folder to a backup of where I was at this morning before attempting anything. I can confirm my Windows account (Admin, and only account on the computer) has full read and write access to all Folders and files within the Mozilla folder, although I will mention some of the files in the Firefox folder were marked with the "Read-Only" attribute (not sure if that matters, but I tried unchecking those and still no luck)

As far as I can tell I have thoroughly exhausted all the easily accessible tips on the internet for solving this, so I am wondering what to try next?

TLDR: Error: Your Firefox profile cannot be loaded. It may be missing or inaccessible" Already Attempted (And failed): -deleting and prompting a remake of the profiles.ini folder -using firefox.exe -P to launch Profile manager -deleting Firefox folder to prompt a remake of that -multiple uninstalls and reinstalls of Firefox -manually remaking profiles.ini file after it didn't come back after deletion

Will link images of (1) profiles.ini file. (2) Profiles folder.

Hello, I’m having trouble getting Firefox to work properly on my computer. During installation, the setup process becomes very slow, and once I manage to install it, Firefox hangs or becomes unresponsive within a few seconds after launching.

My system details:

Operating System: Windows 10 64-bit

What I’ve tried so far:

Reinstalling Firefox Running in Safe Mode Clearing profile data Disabling antivirus temporarily

None of these steps solved the problem. There are no specific error messages — the browser just freezes, and I have to close it via Task Manager.

For some reason every time I open Firefox the window closes. I can see it's open on my dock, but if I click on it, the window opens and closes again. It's so fast I can't even go to the setting for Firefox. Anyone knows what's going on?
