When i close firefox it runs in the background consuming noticable processing power.why? and how do i stop it?

This only happens occasionally and the only reason why I found out it was firefox is by opening up task manager and selecting the Processes tab. There is no crash reporter or any thging to say there was a problem just a reduction in speed and performance.

This is generally caused by a problematic add-on. See this article on possible solutions: [[Firefox hangs#w_hang-at-exit]].

    when I set my screen saver to iLibrary it defaults to national geographic,why and how can I stop it

    Back up all data. Quit System Preferences if it's running.
    Triple-click anywhere in the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:
    ~/Library/Preferences/ByHost
    In the Finder, select
              Go ▹ Go to Folder...
    from the menu bar. Paste into the box that opens (command-V), then press return. A folder named "ByHost" should open. Look inside it for a file with a long name that begins "com.apple.screensaver". There may be several such files. Move them all to the Trash.
    Log out or restart the computer. Test. If the problem is resolved, empty the Trash and recreate your settings in the Screen Saver tab.

  • Firefox constantly runs in the background even when closed

    Hi
    I have Firefox 3.6.8 running on Windows Vista.
    I have found that Firefox constantly runs in the background even when i have just booted up the computer or when i have closed it.
    Firefox seems to constantly run with 5000-20000 K bytes in the memory.
    When i have Firefox running to look at webpages, there are two processes running. When i close Firefox there is one process running. If i end the process using the task manager, it only takes seconds before it starts to run again.
    I know this isnt normal because i keep a good eye on the processes running on my computer. So unless the latest version of Firefox requires this process running all the time, it looks like i have a probably.
    Ive scanned my computer with zonealarm, avast, superantispyware and spybot to scan my computer for viruses. One of the pieces of software found a virus and it deleted it successfully.
    Im not too sure if this is a virus that is hiding in my system or whether its part of the latest version of Firefox.
    Firefox isnt showing the usual signs of a virus. As in it doesnt try to redirect me to random websites and it doesnt try to get me to download something.
    I hope someone can help me please.
    Rob

    After talking to someone very helpful on the live chat support.
    It appears like i have a virus that is very good at hiding from detection from anti-virus/spyware software.
    No idea what intentions the virus has as its not showing any sort of virus like behaviour.
    I called the old installation a different name and closed the Firefox process. A few seconds later, instead of a Firefox process starting again a different executable started.

  • My firefox is running in the background, unvisible. It will not allow me to uninstall/ reinstall because it says it is running. I cannot create a new profile because it says that firefox is running? How do I fix this??

    I have tried restarting my computer, tried uninstalling, tried reinstalling but it always tells me that Firefox is open and running. When I select the task manager, there is no "firefox" under process. I have tried checking to make sure that the "read only" box is not checked under the profile properties. it seems like my only option now is to create a new profile. However, the profile manager won't even come up because it says firefox is running in the background. So frustrating!

    Do a clean (re)install and delete the Firefox program folder (C:\Program Files\Mozilla Firefox\).
    Download a fresh Firefox copy and save the file to the desktop.
    * Firefox 8.0.x: http://www.mozilla.com/en-US/firefox/all.html
    Uninstall your current Firefox version if possible.
    *Do NOT remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
    Remove the Firefox program folder before installing that newly downloaded 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.
    Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
    You can force Firefox to create a new default profile if you remove the profiles.ini file.
    * http://kb.mozillazine.org/profiles.ini_file
    You can find that file here:
    C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\
    The "Application Data" folder in XP/Win2K and the "AppData" folder in Vista/Windows 7 are hidden folders.

  • I keep having to restart my computer. It say firefox is running in the background but I cannot load another page

    I keep getting the message that Firefox is running in the background and I cannot load another page. I have to restart my computer to get Firefox back to operating normally. I have everything closed down as far as I can tell. But when I click on the Icon it will not start another page. It just keeps telling me to shut down all browser windows and that Firefox is running in the background. I even go to ctrl/alt/delete and look at the tasks running. Nothing! It is happening a lot more often now and I hate to use Internet Explorer. I have depended a lot more on Mozilla in the past few years now and I like it. This is driving me nuts. Please help. Thank You

    Did you check the Processes tab in the Task Manager?

  • For some reason when my daughter sends a text to someone else I get it and vice versa.  Also, when I send a text to her the text comes to me as well.  How do I stop this from happening?

    For some reason when my daughter sends a text to someone else I get it and vice versa.  Also, when I send a text to her the text comes to me as well.  How do I stop this from happening?

    This is iMessages, not an SMS/MMS, and this means the same Apple ID is registered for iMessage on each iPhone.
    You or your daughter need to activate your own Apple ID for iMessage and FaceTime. The same Apple ID can continue to be shared for iTunes store downloads - for music and apps.
    On the iPhone, go to Settings > Messages > Send & Receive.   Select the Apple ID at the top and sign out.   Sign in with the new Apple ID.
    Make sure the same email address is not available below You can be reached by iMessage at on each iPhone.

  • Why does my iMac display keep shutting off?  Computer still running in the background.  I've tried unplugging and restarting, to no avail.

    Why does my iMac display keep shutting off?  Computer still running in the background.  I've tried unplugging and restarting, to no avail.    The computer is well out of warranty - about 7-8 years old, running 10.6.8

    Checked.... the settings had not been inadvertently changed, but I did move the scroll and reset them back to the original.   Hasn't shut off again.... yet.   Will re-post with follow-up one way or the other.   Thanks.

  • I only see the phone numbers of my contacts when using iMessage on my MAC, whereas I see the names on my iPhone. Why, and how can I make it so I see the names (and pics) on my MAC?

    I only see the phone numbers of my contacts when using iMessage on my MAC, whereas I see the names on my iPhone. Why, and how can I make it so I see the names (and pics) on my MAC?

    Thanks Eric, but that was already turned on. I just now tried turning it off and on again, no change. Actually, I"m more interested in seeing the names than the pictures. I now only see the phone numbers and generic avatars where pics would be.

    AdaS_VZW,
    I'm not sure if the area has been surveyed; it's a large group of apartment buildings about a within a couple miles of Dulles International Airport in Northern Virginia, so I would imagine that it probably has, but I'm not sure. How would I find out?
    I understand that the Network Extender does not support LTE connections (I know there are two models, the 1x-only and 3g, both made by Samsung - I have the 3g model, SCS-2U01). I know that it can support a 3G data connection, but that should be irrelevant - I'm always connected to my wifi network in my apartment.
    What's particularly vexing, however, is that both a Galaxy S4 and Galaxy Nexus in my apartment (the other lines on my account) do not seem to have this issue. While I haven't done so with the S4, the Nexus exhibits this problem when my SIM is in it - and again, this is a fresh SIM from just a few weeks ago.
    I'm currently trying to disable Mobile Data when in the apartment to see if that will make it more stable. I'll post in a day or two with results from that.
