Firefox will not start on limited account. Reports firefox already running but doesn't show in task manager. Adminstrator account work fine

Firefox will not start on limited accounts. It reports firefox already running. This happens even if no other users are logged on. Administrator accounts have no problems accessing firefox

Create a new profile as a test to check if your current profile is causing the problems.
See Basic Troubleshooting: Make a new profile:
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

  • Firefox will not start up, there is no other instance running, and profile manager will not start either.

    I try to start Firefox, but it just doesn't start. I have tried every way of starting it I can think of. Nothing that appears Firefox related shows up in the task manager process tab. I don't remember having any kind of crash. There is no error message. (If I click on a URL in an email or something, I get a "general failure" message -- I assume that's because my system is supposed to open FF and can't.)
    I rebooted, and tried uninstalling and reinstalling. One of the help thingies suggested using profile manager to change my profile, but it looks like profile manager is part of Firefox, and it won't run.

    Make sure that Firefox is completely closed, when you try to run the profile manager.

  • Firefox will not start because "A copy of Firefox is already open. Only one copy of Firefox can be open at a time".

    I had a major crash of Firefox - maybe virus or malware. I think computer is clean now. I deleted all Mozilla/Firefox files I could find and re-install Firefox. Will not run in safe mode (same error).
    Since I deleted Firefox/Mozilla files, I can not supply crash information/logs :(
    It runs fine on another computer on my network, this MacBookPro, same OSX and version of Firefox.
    Profile Manager?

  • Firefox will not start (crashes on opening) following upgrade to Ubuntu 10.10; crash report specifies IcedTeaPlugin.so

    After upgrading to Ubuntu 10.10 (Maverick Meerkat) beta, Firefox will not open. A crash report is generated each time. Looking at all the crash reports, they specify the IcedTeaPlugin.so @0x7cec as the point where the crash occurs.

    I was also having the same problem but it disappear once I removed the icedtea plugin from synaptic. After that I tried to re install the icetea plugin again and there was no issue in firefox, it started normally.
    My icetea6-plugin version is 6b20-1.9.1-1ubuntu3

  • Firefox will not start and any attempts to do so opens a crash report which neither properly closes nor restarts firefox.

    firefox was working this morning but in the afternoon, after i got off a game that did not require use of firefox, firefox would not start. it does not show up in the task manager and typing "firefox.exe -ProfileManager" into the search box opens a crash report which neither restarts firefox nor quits it. further attempts to do the same results in the same crash report.
    restarting the computer does not help.
    previously, in the past week, firefox has been frequently crashing. however, this afternoon was the first time firefox would not start at all. cannot uninstall firefox as my system provides no response.

  • After removing system fonts and reinstalling fonts, FireFox will not start

    After removing system fonts and reinstalling fonts, FireFox will not start! When I start FireFox the "Mozilla Crash Reporter" opens as if FF just crashed??? I don't see any records in event viewer. I am using FF v3.6.3 on a Windows 7 box. I tried uninstalling 3.6.3 and installing 3.0.18 and had the same problem!
    == This happened ==
    Every time Firefox opened
    == After a uninstalled all fonts including system fonts and then reinstalling system fonts. ==
    == User Agent ==

    The files with submitted crash report ids are inside the ''submitted '' directory, from the directory you found the LastCrash.txt timestamp file.
    The file names will begin with '''bp-'''
    There might be more information from the crash report, but it might just tell us you are crashing the first time Firefox tries to use a font.
    One thing I suppose you could do is select only those fonts you've got in Tools -> Options -> Content -> Fonts and Colors -> Advanced and then uncheck the '''Allow pages to use their own fonts''' option.

    To be honest, I can't find anything on this Netscape Font Navigator and it sounds highly dubious.

  • Firefox will not start at all

    New versions of Firefox will not start and only bring up the crash reporter. I've tried starting in safe mode, I've deleted/created new Profiles and I've uninstalled/installed Firefox over and over. I can still download 28.0 and it has no problem opening. Below is the latest Crash ID from 35.0
    Crash ID: bp-4ac8fb2d-9a2a-4a6a-a9e4-06cc42150125

    hello sid.robinson, this crash is caused by the "Digital Guardian" software by Verdasys that is running on your computer. Please see if there's an update available for that program.

  • Firefox will not start after computer restart

    Install Firefox, runs fine. Restart computer, Firefox will not start or finally when it tries to start script errors occur. If I reinstall Firefox after a computer restart, it will work fine, again when the computer is shut down the next time it is started, will not be able to use Firefox. Firefox will not start up in Firefox safe mode, will not start in windows safe mode. Not add on's, nothing added, just the Firefox installer Performed complete system restore on the computer, same problem. Windows 7 Pro. Remove Firefox from windows control panel, restart computer, install firefox, will run. turn off computer, turn on computer, firefox will not start or freezes. I am interfacing the internet via Explorer now.
    I have reinstalled Firefox so it will run in order to perform the steps requested below.

  • Firefox will not start any more.

    Firefox will not start. (reported as a hang)

    Try Application > Utilities > Activity Monitor and look in the Process Name column to see if there is a version of Firefox there.  If so, select it and then hit the Quit Process icon.
    Restart Firefox.
    Recently, Firefox has repeatedly started hanging on my 10.7.2 iMac.
    If that is not it, try Carolyn's suggestion.

    Thanks for your help. I had tried starting Firefox in safe-mode before I posted this request, but it did not work. I tried to restore the system to an earlier version, but that made everything worse. Two accounts were unusable and one sort of worked, so I reloaded the operating system and now firefox works, for how long, I don't know. But thanks again for your suggestion.

  • Firefox Will Not Start Up

    Firefox Will Not Start - I have tried the Profile Manager to create a new profile, but when I try, it goes to a different screen explaining that "Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts" But Firefox will not restart when we prompt it to.
    == This happened ==
    Every time Firefox opened
    == I was browsing videos online

    Make sure that Firefox is completely closed, when you try to run the profile manager.

  • Firefox will not start, after reboot.

    For a few months now Firefox will not start after I reboot my computer. In order to get it to start I click the exe then must go into task manager kill it, click the exe again, kill it again then, from there it will typically start, but sometimes it may take one or two more trys. When clicking the exe firefox will appear in the task manager under processes but will will start with ~7% CPU usage, then quickly drop to zero every time until it does actually open and start. I have ran a full system recovery and started anew after reinstalling mozilla several times failed to fix the problem. I run virus and spyware checks often and come up clean, and also run Chrome as a default browser.

    Hello Tom.
    You may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
    Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
    If you want support for one of your add-ons, you'll need to contact its author.

    Do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
    Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
    It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
