• Firefox does not start - claims that it is already open

  Firefox does not start. He claims to be already running, but that doesn't seem to be the case.

  I tried to create a new user profile, but when I try to open Firefox now, the menu "choose user profile". I tried the new profile and they old, and both give the same error message. "Firefox is unable to use the"Default user"profile because it is in use. To continue, close the Runspace of Firefox or choose a different profile. »

  There is an entry for firefox.exe in the menu of "details" to my task manager and nowhere else. When I try to put an end to this task, I get the following error: "the operation could not be performed - access denied."

  Due to some troubleshooting research, I tried to delete the parent.lock my profile folder, but I get this error: "the action cannot be completed because the file is opened in Firefox."

  I tried to transfer my bookmarks and preferences from Firefox to Chrome, but I had a similar error suggesting that Firefox was already open and I have to close first.

  I also turned off my computer and uninstalled and reinstalled Firefox several times.

  I'd really rather not lose all my bookmarks Firefox, modules, and preferences. I also prefer to use Firefox for Chrome, so if anyone can help me I would really appreciate it. I don't know what else to try.

  My PC runs Windows 10, incidentally.

  Try to delete the parent.lock file in the Firefox profile folder.

I don't usually to reinstall immediately because I need my passwords and username back. I can't find a solution on the forums, or if there is I have not found or I simply did not understand the solution itself. Please get back to me as soon as possible

  Thank you!

  Is a restoration of the system to a cancellation of the recent updates or something more radical?

  You can do the following type of reinstall without touching your settings files. Important: uninstall NO Firefox first. That is not necessary.

  Clean reinstall it

  (1) download a fresh Installer for Firefox 36 of https://www.mozilla.org/firefox/all/ in an ideal location. (Scroll down your preferred language).

  (2) the release of Firefox.

  (3) to rename the program folder

  (Windows 64-bit folder names)

  C:\Program Files (x86)\Mozilla Firefox
  

  TO

  C:\Program Files (x86)\OldFirefox
  

  (Windows 32-bit folder names)

  C:\Program Files\Mozilla Firefox
  

  TO

  C:\Program Files\OldFirefox
  

  (4) run the installer you downloaded in the #1. It should automatically connect to your existing settings.

  When you start Firefox, you may need to use the Profile Manager to return to your regular profile. Ignore: copy/paste glitch.

  Any improvement?

  Note: Some plugins can only exist in this OldFirefox file. If it is missing something essential, present in these files:

  • \OldFirefox\Plugins
  • \OldFirefox\browser\plugins

• Firefox does not start after the computer restarts

  Install Firefox, works great. Restart the computer, Firefox does not start, or finally when it tries to start the script errors occur. If I reinstall Firefox after restart of a computer, it works fine, once again when the computer is stopped at the next startup it is, will not be able to use Firefox. Firefox does not start in Firefox Safe mode, does not start in windows safe mode. Do not add now, nothing has been added, just the Firefox installer played complete the system restore on the computer, same problem. Windows 7 Pro. Remove Firefox from windows control panel, restart your computer, install firefox, will take place. shut down the computer, put on the computer, firefox does not start, or crashes. I am exploring now Web interface.

  I reinstalled Firefox, so it will run in order to perform the steps below.

  Here is the answer which took care of the problem,

  "Site Web TrueSuite Log On" plugin (AuthenTec), is the question.

• 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 start. Error oxc0150004

  Firefox will not start. I uninstalled and reinstall.
  Nothing has changed. I have used Firefox for years. This first
  time, I have a problem.

  Hey Horrie.

  Have you tried to start Firefox in Mode safe? Key 'shift' startup of Firefox. If the accident is not in Mode without failure, you should read the extensions, themes and problems of hardware acceleration to resolve common troubleshooting Firefox problems.

  There are also a lot of useful things in the article Knowledge Base of Firefox does not start . If you have recently upgraded, you can check out this article as well.

  Hope this helps!

  Disable the extension "McAfee Site Advisor" who has just updated 3.4.0 that probably out of block of addons list.

  • 'Ctrl + Shift + A' > find McAfee Site Advisor and use 'Disable', and then restart Firefox.
  • Do a Google search without problem
  • It seems that if you re - enable new Site Advisor and restart Firefox you agree. At least you know where to look if you get the error again, or research on Google to slow down.

• AiOSoftwareNPI (* .ms) the Setup program does not start when I start my computer.

  original title: AiOSoftwareNPI

  I'm having a problem with a software AiOSoftwareNPI problem (* .ms) the Setup program does not start when I start my computer.

  I know it's a Windows Installer but I don't have a disc with this route. I even tried to reinstall the windows xp disk and it does not work, I still

  get the same box when I shutdown and restart. The box allows me not to leave him continues to appear.

  Thank you

  Ms. C

  After doing a Google search for AiOSoftwareNPI and followed by the reading of many different threads in various forums, I found that it is for drivers for an HP all-in-One printer.

  You have an HP printer?

  If so, the usual suggestion was to place your HP printer disk in your CD/DVD drive and restart. After reboot would be installed the necessary files and the pop - up would more appear at startup. I don't know if it will actually work because in all the discussions I've read, none of the original poster never responded by saying that it worked or not.

  The next most common suggest was to download the latest driver for your HP printer to your version of Windows (including at the level of the ILO) and install it. Yet, not a single original poster has responded.

  In fact, if you have an HP printer I suggest to visit the web site of HP support below the link to get the latest drivers and their installation. Visit the support for the correct installation method and if you need to remove the old driver first. You can also visit the communities of Support HP for assistance (a link for communities is also on the next page).
