  Firefox Pei does not start the Profile Manager. Firefox version: 50.0

  Have you tried; Type of topic: profiles in the address bar.

• Impossible to load profile, the Profile Manager are not available, firefox does not

  It is somewhat similar to the other listed problems with Profile Manager, but none of the answers worked for me. OS is Win 8-64 bit. Have 2 user accounts. Admin and Limited. In Admin, Firefox works, can access the Profile Manager, there's this profile.ini etc. All right.

  But in the limited account cannot access Firefox. When you click it, it says "Firefox your profile cannot be loaded. It may be missing or inaccessible. Can't access the Profile Manager "C:\Program Files (x 86) \Mozilla"-p. gives the same error message (Firefox does not).

  Tried to copy the files in the Admin in Limited. But the error message is the same.

  Uninstalled and installed using the limited account (supply Admin password), no result.

  Please help me.

  Thank you for your time.

  Hi Cor - el, ideato,
  Thanks for the support.
  When I entered the command, it gave me the error "the file name, directory name or volume label syntax is incorrect."

  I tried the command in different ways, but the results were similar.

  When I tried in the Admin account, it worked. But not in Limited account.

  In any case, after a long period of time, I managed to solve the problem (well sort of).

  That's what I did;
  1 uninstalled Firefox from Windows Add/Remove programs
  2. manually deleted all the files that were there for Firefox.
  3 created new account limited ('Test')
  4. sign in to that account and then close.
  5 installed Firefox using the Admin account.

  She's. Inside this 'Test' (limited), Firefox works fine. Unfortunately, inside 'Limited' Firefox is still inaccessible. But it doesn't matter. What I need to work Firefox in a limited account. I can remove 'Limited' and rename the 'Test' in 'Limited '.

  Thank you for your continued support. I learned a lot from your instructions!

  Happy troubleshooting!

  Thank you and best regards!

• When the Profile Manager stores data profiles created?

  I have several profiles of Firefox that I created with the Profile Manager, but I find no where the Profile Manager stores data for profiles created because even if I delete all the firefox location of C:\Users\user\AppData\Local\Mozilla user data files and all the data in the registry though Firefox I start the Profile Manager still lists all created profiles.

  Then, where the data for profiles created is stored?

  Hello, these data are stored in subfolders of \Mozilla\Firefox\Profiles\ C:\Users\user\AppData\Roaming- profiles - where Firefox stores your bookmarks, passwords and other user data

• Firefox does not open, the Profile Manager does not, are not not in the Task Manager

  Firefox worked fine on two days back. Our norton expired so I downloaded Kaspersky Anti-virus 12.0.0.374. I don't know if that has a relationship with firefox does not.

  I click the icon, nothing happens. The task is not mentioned in the Task Manager.

  I try to start it in safe mode, nothing happens. I try to open the Profile Manager, nothing happens! What can I do to fix this?

  Can you run Firefox if you temporarily disable Kapersky?

  You can download and reinstall Firefox if the above does not work

• the call firefox.exe - ProfileManager does NOT open the Profile Manager does NOT create a new profile, KILLS the old session tabs, but all pinned!

  FF 7.0.1 on Win7 pro 64

  A behavior more bug / odd:
  calling "firefox.exe - ProfileManager".
  -do NOT open the Profile Manager,
  -does NOT create a new profile,
  -seems to do NOTHING (no change around records profile etc.).
  but...
  -KILLS tabs former session.
  -KILLS old session and leaves nothing to restore,
  -KILL all my pinned tabs!

  OK, I should downgrade to FF4.0.1, or same 3.6.x?
  These releases are much more reliable than 6 + 7 running!

  Try using this:

• Firefox, or the Profile Manager will start. In my task manager, the process uses 50% of my cpu but does nothing. I like browsing with firefox, how do I fix?

  I tried to restart my computer, the I tried to uninstall and reinstall uninstall, delete all files of firefox and folders, then reboot and then reinstall. Also, I tried to open the Profile Manager to edit my profile. After you have reinstalled several times and try to open the Profile Manager before launching firef0x, I got the firefox crashed window and the process in the Task Manager always uses 50% of my cpu. The most recent strike and then re - download gives me an error "the file is corrupt" and will not even install the program.

  Kill the process that you see, including any plugincontainer.exe, only once firefox has stopped running don't try to update.

  Completely unexpected instances of firefox running can sometimes be the result of malware activity.

• Firefox does not start (not safe mode), but uses the CPU

  I have the latest Firefox 25.0 (and the last Flash 11.9.900.117) on Windows 7 and the following behavior is reproducible. It started not too long ago.

  At first when I launch Firefox, nothing appears no matter how often, I restart. I see in the list of the process firefox.exe to 25% of the CPU, 2 x FlashPlayerPlugin_11_9_900_117.exe (CPU 0%) and plugincontainer.exe. No matter how many times I killed all of them, would not restart Firefox.

  The following also not help in this situation:

  • Starting in normal safe mode: Firefox opens a window but immediately freezes and does not respond. The process list shows the same process even if I find the unexpected FlashPlayer.
  • Disable plugincontainer: same results (just without plugincontainer.exe)
  • Uninstall Flash: Same results (just without FlashPlayerPlugin)

  The following can start Firefox only once:

  • Starting in SafeMode but select "Reset Firefox": Firefox does not start right away, however. Nothing happens, and you have to kill the process. However the very next time you launch Firefox in the normal way, it works fine (but it shows FlashPlayerPlugin.exe in the list of unopened Windows process despite the tab). Unfortunately, after closing Firefox the process (Firefox, FlashPlayerPlugin) are not deleted. I kill and the problem with Firefox do not leave reappears.

  In case you use "clear history of Firefox closing:

  • do not delete Cookies

  Note that compensation "Preferences of Site" clears all exceptions for cookies, images, windows pop up, installation of software and passwords.

  Use "Firefox > output" (Windows: Firefox/file > quit;) Mac: Firefox > quit Firefox. Linux: Firefox/file > exit) to close Firefox if you are currently doing by clicking on the X close in the title bar of Firefox.

  Create a new profile manually (and not via the reset) as a test to see if your profile is the source of the problems.

  See "create a profile":

  • https://support.Mozilla.org/KB/Profile-Manager-create-and-remove-Firefox-profiles
  • http://KB.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

  If the new profile works then you can transfer files from a profile in the new profile, but be careful not to copy files corrupted to avoid transporting on the problem.

• Firefox does not open. Hangs during 'connection '. Inadmissible even in the process of closing via the Task Manager.

  Yesterday, Firefox does not open. It hangs at the "stage of connection." For hours. It doesn't even turn off using the Manager of tasks for applications or processes, and it hangs almost all other applications. I thought that I managed to save a Word document opened yesterday - it looked like a slow, but normal save during the shot of Firefox, but the document was empty when I restarted my computer.

  Although my machine is not pentium 4 in service, I tried to start by using the configuration of Windows XP/M, I downloaded and re-installed (above) the existing version, I checked that no process of Mozilla turned before trying to start Mozilla and tried to create a new profile. Absolutely no success. Every time (dozens), I tried to start Firefox, I had to force a difficult to exit the application shutdown. I now have this marking Firefox in my taskbar, because I keep forgetting and hit by reflex.

  I am running version 11.0 (at least that's what I just downloaded - I am not positive of what I was running yesterday). My system is Windows 7 Home Premium, Intel Core i3 2.4 gHz, 4 GB of RAM, 64 bit OS.

  Next option is to restore to an earlier version. If this does not work, I uninstall and start again from scratch.

  I disabled AVG (antivirus free 2012) for 10 minutes, open Firefox and browsed a bit. Close the browser, whereas the temporarily disabled AVG activated itself again and restarted Firefox. Now, it connects perfectly - several times faster than prior to this incident (I have installed v 12.0; previous version was 11.0). I use the Microsoft Firewall, if while the firewall solution suggested above has not worked, he put me on the right track.

• I can't start Firefox (suddenly) or I can open the Profile Manager, what to do next?

  Windows 7, 64 bit. Experienced some Windows updates, but I restored before the updates and still failed to open Firefox. Can open Safari and IE.

  There is a problem early enough in the process if the Profile Manager does not start.
  You can try in Firefox safe mode then you can try in Windows safe mode using the F8 key.

  What you're saying, I wonder if you did a restore of Windows of some form and recreated Firefox like this. Firefox does not always correctly restores windows. You might be looking at re - install Firefox.

  If you are considering relocation do take all options of Windows or Firefox that offers to remove personal settings because that is going to destroy things like passwords and bookmarks.

• Firefox does not start after the places.sqlite opening in Notepad

  Firefox does not load again. I tried to create a large folder of bookmarks, but I wanted them to hide so I tried to be clever and create a copy of my current places.sqlite who had no bookmarks added and moved elsewhere, then I added bookmarks and once that replace the current places.sqlite then I created a copy of this and put it elsewhere for more security and then I replaced it with the first places.sqlite I had copied. I had to go through that much trouble because for reasons, I was unable to delete the bookmarks by right-clicking and selecting delete. I had already tried to open places.sqlite in Notepad and since then is when it started to happen. I tried to reset the file extension type, or rather detached, but I can't figure out how. I also tried to remove completely any Mozilla partner, restarted my computer and then reinstall Mozilla, but it didn't work and I prefer not to try again or uninstall it because my computer has a very difficult time even boot Windows 10. He likes to get on the desktop and then never hang while I have to restart the computer continuously until it works.

  Can someone tell me what to do or where it is that I was wrong?

  Do a clean reinstall and delete the program folder before Firefox to (re) install a new copy of the current version of Firefox.

  • Download the installer of Firefox and save the file to the desktop
    https://www.Mozilla.org/en-us/Firefox/all/

  If possible to uninstall your current version of Firefox to clean the Windows registry and settings in the security software.

  • Do NOT remove the "personal data" when you uninstall your current version of Firefox, because this will remove all profile folders and you lose personal data such as bookmarks and passwords including data profiles created by other versions of Firefox.

  Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

  • (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
  • (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.
  • It is important to remove the Firefox program folder to delete all the files and make sure that there is no problem with the files that were the remains after uninstallation.
  • http://KB.mozillazine.org/Uninstalling_Firefox

  Your bookmarks and other personal data are stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but do NOT delete personal data when you uninstall Firefox which removes all Firefox profile folders and you lose your data.

  If you keep the problems, and then create a new profile.

• Firefox does not open. Keep saying the profile is missing. There is no profile of AppData\Roaming\Mozilla\Firefox\

  I'm on Windows 7 OS.
  I read a lot of similar and related problems anywhere as my own, but none of them has a solution that works.

  I get the error message saying "unable to load your Firefox profile. It may be missing or inaccessible.

  I checked Windows: %AppData%\Mozilla\Firefox\
  C:\Users\ < user > \AppData\Roaming\Mozilla\Firefox\

  Only thing it is a folder called Firefox and in that one a file called crash report.

  There is no not called "profiles.ini" file so I have no way to access the Profile Manager and uninstall + remove manually all related Firefox folders/files and reinstall Firefox does not solve my problem.

  I have no idea what to do to get out of here to go to solve this problem or difficulty why Firefox doesn't work anymore even when the reinstalled.

  Have you tried to rename the Mozilla folder?

  Also try to delete the folder to the location of the cache in AppData\Local.

  • C:\Users\ < user > \AppData\Local\Mozilla\Firefox\Profiles\

• Firefox does not open and not get Profile Manager.

  I'm running Windows 7 Professional. So about two weeks ago, I had suddenly couldn't open Firefox and since then have tried to solve it myself does not. the process of Firefox opens in the Task Manager, however, the browser window does not appear. Trying to open Firefox again, another process opens and the same thing happens. Process just keep opening and that's it. I tried the Profile Manager, but it opens only once and I couldn't so he can reopen. Every once in a while Firefox actually opens when I run it, but when I close it to see if it works once again it does not work. Firefox opens in safe mode with network consecutively without any problem. While he was in safe mode, I ran a full scan of the system with Nortan Antivirus and allowed thirty or threats, but after restart of Firefox will not always open, treated only. I tried to remove the x 86 erased my local path and Mozilla appdata roaming Mozilla, then re installed with 34.0.5. I tried to open Firefox in safe mode, but it will not open at all, only the process again.

  It is possible that your security (firewall, antivirus) software blocks or limit Firefox or the process of plugin-container without you inform, possibly after the detection of changes (update) for the Firefox program.

  Delete all rules for Firefox and the plugin-container in the permissions list in the firewall and allow your firewall to ask permission to get access full and unrestricted, again to install for Firefox and the plugin-container and the update process.

• After installation or upgrade to Firefox 31, starting Firefox does not display the home page, personalize displays a blank page and the radio button does not work

  I am the admin of Windows for a University Department and install PC with Firefox all the time. This problem does not occur with every PC I would maintain, only a selection bit (model different laptops with Windows and update 1 8.1.) Until today, it has happened with the new user (with admin rights) accounts that I place on laptops for our staff. Today, this happened with the account administrator while setting up a new laptop. In all cases so far, I have install Windows from a registered image that was created by using sysprep.

  I tried many suggestions to reset Firefox, removing the profile of Firefox users, removing the Windows profile users, uninstalling/reinstalling Firefox, uninstall/reinstall of Firefox and the latest Java, but nothing helped. After uninstalling, I run an application to delete the caches and temporary files and even remove manually the keys to register HKLM\SOFTWARE\Mozilla and HKCU\SOFTWARE\Mozilla. I restart and make sure that the installation folder is deleted after uninstalling.

  Results are the same: after installing Firefox 31, the initial settings for migration, IE or Chrome pop up and after having clicked on the button finish, Firefox starts but does not display the home page of the new user, only a blank page. By clicking on the Options (3 bars) button does nothing. Right click in the appropriate box, the shortcut menu appears, so I can choose to customize, but which opens another tab with subject: Customize the URL and the page is blank. In the right click context menu, I can activate the menu bar and get options from that.

  My last attempt helped a little. I uninstalled Firefox 31, cleaned, removed the profile user Firefox, rebooted and then installed Firefox 30. Initial start-up runs and tells me that I'm not up-to-date and the works of button Options. But I can't always customize.

  Then I upgraded to Firefox 31, but then it's back to no start page, no options button and no customization. I can go down to 30 and get customize practically works again.

  Addon only is for McAfee Scriptscan to Firefox 15.1.0, just after installation is disabled.

  Any help would be appreciated. Thank you.

  You can try a different theme of Windows?

  Have you tried to start the computer using Windows safe?

  Start the computer in Mode safe mode with network support Windows (on the startup screen, press F8) as a test.
