  • Firefox is running in the Task Manager, but only opens a window.

    I can't get Firefox to open a window. I tried firefox-p (Profile Manager) and firefox-safe (safe mode), but nothing works to open a window. I uninstalled and reinstalled, but that solves nothing. I haven't changed anything recently, so perhaps there is a update (?) Here's what happens:

    I try to start Firefox, and the Task Manager indicates that Firefox is running. It employs about 32 k of memory, but the window never opens.

    I click Firefox again. Manager tasks indicates 2 Firefox process now. The second is to use about 4 k of memory. Running Firefox repeatedly adds additional tasks to Firefox, each using about 4 k of memory.

    After about a minute, the additional tasks of Firefox (the 4 k ones) start closing 1 by 1. I am now down to only 2 Firefox process, using 32 k and 4 k of memory, respectively. As far as I know, these processes will last forever, until I have shut them down manually. If I run Firefox again without closing the current process, it creates another 4 k process, which finally closes itself. If I close all the processes manually, I can start over from scratch. Meanwhile, Firefox never opens a window, or give a clue showing that it is running, with the exception of the processes listed in the Manager tasks.

    I deleted the one in my USER folder without change. There are a couple more in various C:\Mozilla\Firefox\Profiles files, so I deleted those too, without change.

    It's a custom location. Normally, the profiles are under AppData\Roaming, I think you already know. There is a shortcut:

    %APPDATA%\Mozilla\Firefox\

    This folder must contain a profiles.ini file (.ini file extension may be hidden), which shows the names and paths to your profile folder (s). If you check in a text editor such as Notepad, this file contains sound data?

    If this started right after an update, it could be a problem with security software, put an end to the commissioning (rules of program control) or program files has been corrupted.

    You can check your firewall and other security software for program restrictions.

    To meet possible corrupt files, I suggest:

    Clean reinstall it

    We use this name, but it isn't about deleting your settings, this is to ensure that the program, files are clean (no incompatible or exotic code files). As described below, this process does not disrupt your existing settings. Don't uninstall NOT Firefox, that does not need.

    (A) download a fresh Installer for Firefox 43.0 https://www.mozilla.org/firefox/all/ in an ideal location. (Scroll down your preferred language).

    (B) the release of Firefox (if any).

    (C) to rename the folder of the program as follows:

    (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

    (D) to run the installation program that you downloaded in step (A). It should automatically connect to your existing settings.

    A cleanly reinstalled Firefox starts up normally?

    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 is running in the Task Manager, but the browser does not open.

    This happened after the most recent update v 27. Gateway win8 running, working every day before this update, doesn't work now.

    Thanks for this information. I tried to move that file saved passwords, but while the instructions are clear... because the instructions lead in the new profile only... not how to copy files from the old profile (or maybe they did and I'm not) I think I'll just skip this step and just manually enter them as visited Web sites ask for them. .

  • 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":

    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, no error message, only works in the background

    I click on Firefox it does not start
    no error message it does not start
    It works in the background in 32-bit
    I have re installed it but nothing changes

    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 leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

    Hello Varshil07,

    Thank you for using communities of Apple Support.

    If I understand your message, by updating your Mac you have forced stop, or you have closed the lid, and now it does not start.  To start, I suggest that try you to start in safe mode by following the instructions below.  For later use, it's a good idea to not force the computer to shut down or close the lid while it is up to date, because it can cause problems.

    1. Choose the Apple menu > shut down.

    2. After your Mac stops, wait 10 seconds, then press the power button.

    3. As soon as you hear the startup tone, hold down the SHIFT key.

      You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.

    4. Release the SHIFT key when you see the gray Apple logo and progress indicator.

    To exit safe mode, restart your Mac, but no press during the startup.

    OS X El Capitan: start in safe mode

    Have a good.

    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?

  • Firefox does not start until the wifi is active

    I'm trying to use the latest firefox (v32) on Debian/testing/64-bit by using the 64-bit version of FF... This machine is a laptop and is used only with wifi. The wifi that is usually used is a Starbucks or McDonald's who require a click on a Web page before the connection is enabled... When I start FF to be able to select this check box, it does not start. a look at the ps - xua shows firefox as a zombie/missing process... How I work around this, is to use Google Chrome to shoot to the top of the Web page, click on the box, then almost immediately the instance FF I tried to launch rises... If I clicked on the icon of the FF once more, I get more window a FF... It seems that FF needs a pipe open to internet before it will start. I prefer FF on Chrome, but if I have to use Chrome to "Kick-start" FF, I might as well delete FF and just use Chrome... Any ideas?

    UH... This problem occurs on Linux... It IS not IE (thank God)... The proxy on FF and Chrome settings are identical, namely NO proxy configured...

    I've come up with a workaround.. Switched out the Linux drive with my pretty unused Windows 7 disk.. Where this problem with Firefox doesn't occur.. I'll check back in a few months with FF on Linux and see if one of the endless "updates" has magically fixed this problem.. Thank you for the help anyway..
