Firefox freezes every five minutes, "not responding" for about a full minute at a time then resumes, only to do it again five minutes later

It's just random, about every five minutes everything just freezes. It's not my computer, just the browser. I get the (not responding) in the upper left corner of the browser. I have to keep waiting about a full minute for the browser to resume. This only started happening after I downloaded Firefox 7

Did you give it a try to be sure that that isn't at least part of the problem?
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

  • It always says:Firefox is already running but not responding; what can i do to fix this problem; it has only started after having downloaded the latest verion.

    I downloaded the latest version of firefox and the problem has started; it aways says: "Firefox is already running, but not responding. To open a new window you must first close the existing Firefox process or restart your system; I have to do this about 3 times for the internet to come on again; what can I do, short of calling a technician??

    Please read this article: [[Firefox is already running but is not responding]]

  • Why does my Firefox freeze up and say Not Responding no matter if i`m on a website or e-mail?

    Every time I use my Firefox whether its for browsing online or using my e-mail, it freezes up and says Firefox Not Responding. It has become so frustrating and I would really like to continue running Firefox. PLEASE HELP!

    Try the Firefox SafeMode to see how it works there. <br />
    ''A troubleshooting mode, which disables most Add-ons.'' <br />
    ''(If you're not using it, switch to the Default Theme.)''
    * You can open the Firefox 4/5/6/7 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
    * Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. <br />
    ''Don't select anything right now, just use "Continue in SafeMode."''
    ''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
    If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one. <br />

  • Keep getting firefox not responding for about 2 months now Can any one help me figure out why and fix this?

    I'm using windows 7 64 bit system, for past 2 months keep randomly getting firefox not responding. Wait about 10-20 seconds for all tabs to respond.

    This is a bad hardware error, Baseband Error. Some have reported getting through this error by Restoring iPhone with the SIM Card removed. Try that. Try restoring with different computer. Search Web some more for other thoughts.

  • TB will download 1, display 'not responding' for about 30 sec, then repeat.

    This has become a recurring problem. TB will behave normally, then begin this action. During the not responding, the hourglass will display and the window will be unresponsive to any action. Frequently, downloading will cease completely after several are received and will have to be restarted by clicking the get mail button.
    Although not definitely related, it has been noted that when closed both TB and FF will usually leave behind an open process that will have to be ended before the app can be restarted.
    Please help!!!

    look to your anti virus program. It is almost certainly implicated if not completely the cause.
    Start by disabling email scanning and see how that goes.

  • When i want to go another from a tab,it shows firefox not responding, for a while then opens that tab!this is embarrassing me a lot by taking so much time!!why

    I have two inconviniences with fire fox..
    1)when i want to go another from a tab,it shows firefox not responding, for a while then opens that tab!this is embarrassing me a lot by taking so much time!!why it happens?
    2) every time when adobe flash player is updated, it shows flash player can't be installed and it crashes! it says 'disable real player' though i never installed real player!!
    plz Let me know why it happens to me????

    1. Update firefox to the latest version 2. and disable real player in menu->addons->plugins.
    Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox 13 are most probably caused by a recent Flash 11.3 update and/or a malfunctioning Real Player browser plugin.
    In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:

    First of all, why did you say yes to Nero Back up before researching what it does with files already on the HDD? When I install Nero, the Back Up is the first thing I disable, it is a nagging pain, there are much better backup programs available. There are several file recovery programs out there to recover deleted files, that is, if that is what happened. Also, if you haven't overwritten the files, so you should be able to find them.

  • Firefox keeps "not responding" for a few seconds - then connects

    I just upgraded to Firfox 4.0 because of my new computer's Windows 7.
    It started "not responding" for up to 20 - 30 seconds before it reconnects, and it is sometimes unresponsive to my mouse even when it is working. This did not happen before the upgrade and does not happen with Windows Internet Explorer

    check your system preferences to see if you have "ignore accidental trackpad touches" checked (or something like that). If you type on you keyboard then try to use the trackpad you have to touch it a couple of times so the computer does not think it was an accident while typing. Just uncheck the box if it is checked.

  • Firefox 29.0.1 on Windows 7 (64-bit): ALWAYS get "Firefox is already running but not responding..." error and need Task Manager to close/restart Firefox.

    I run Firefox 29.0.1 on Windows 7 (64 bit) and I get the "Firefox is already running but not responding. In order to open the program you must close the existing window." error. EVERY TIME I try to start Firefox. The posted solution works to start the program, but it is not a permanent solution. I go through the Task Manager and end the old Firefox process, then I can open a new window. While working, I can open multiple tabs and multiple windows, everything seems to (usually) work the way it should. Then after I completely exit Firefox, in order to open the program again I need to fix the SAME error again. Every time. It doesn't seem to hurt anything really, but it is quite annoying.
    I used to get this same error on some of the older Firefox versions but it was only once in a while. With the new 29.0.1 it is literally EVERY TIME I TRY TO RUN FIREFOX!!!!
    So, down to the big question: is there a permanent fix for this yet? Or will there be one included in the next version update? Or am I going to have to go back to Internet Explorer? I know I am not alone in this experience; i've seen several other users posting similar questions but none of them received satisfactory answers. So what's the story here, team Firefox?

    This is not a cure but will make it easier if Firefox locks up.

    == This happened ==
    A few times a week

    Firefox is shutting down windows I want to remain open. Example: I am done viewing one window. I click the X to shut the window and it shuts two windows. Every single time, attempt to close one windows, two windows close. Lately, I have been opening several windows with nothing but google search, just so it will shut that window and not something else I want to remain open. I could understand this if I was using tabs, but I am not. This has been going on for over two weeks. I don't like going back to history to open a window, I did not want closed in the first place. Isn't that what 'Windows' is all about? Any ideas?

  • "Firefox is already running but not responding" - have tried all the usual solutions.

    The message I'm getting is the standard: "Firefox is already running, but is not responding." I'm using a PC with Windows 7.
    I've tried:
    - Opening task manager and manually ending the process. This didn't work because the process is not listed in applications, processes, or services.
    - Deleting the parent/lock file. This didn't work because the file is not in any of the firefox folders. I've checked APPDATA/Local/Firefox as well as APPDATA/Roaming/Firefox, and the original install folder just to be thorough. It's not a hidden file either - I have those set to display.
    - Creating a new profile and importing settings from the old one. I can't import settings because the old profile is still running.
    - Restarting before and after each of these potential solutions, including restarting in safe mode, shutting off the computer and waiting a bit before restarting, etc.
    All I really want back are my bookmarks, which I've spent quite a while creating. Unfortunately, there is no file I can find for the default profile that has the bookmarks stored. When I created a new profile, a folder appeared with its name in the APPDATA/Roaming/Firefox folder, with all of the bookmarks, etc. There is no such folder for the default profile though - which is the one I want. I've even tried switching to Chrome and importing bookmarks, but that doesn't work because the bookmarks can't be imported while Firefox is still running.

    Does a new profile work?<br />
    * http://kb.mozillazine.org/Creating_a_new_Firefox_profile_on_Windows
    If there is no profile present then you also get that error about "Firefox is already running but not responding"
    If you uninstalled Firefox at any time in the past and removed your personal data or deleted that profile folder yourself then you no longer have a profile to start with or restore files from.

    The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
    Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
    To Reset Firefox do the following:
    #Go to Firefox > Help > Troubleshooting Information.
    #Click the "Reset Firefox" button.
    #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
    #Firefox will open with all factory defaults applied.
    Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

  • Firefox won't open when prompted the first time. Says "Not Responding". I have to hit cntrl/alt/del then try starting again. Sometimes multiple times.

    Sounds like a "hang at exit" problem. There are several possible causes for that error. See:
    * How to stop the running Firefox process
    ** In Task Manager, does firefox.exe show in the '''<u>Processes</u>''' tab?
    ** See: http://kb.mozillazine.org/Kill_application
    * What may cause Firefox to hang at exit

    ** http://kb.mozillazine.org/Firefox_hangs
    ** https://support.mozilla.com/en-US/kb/Firefox+is+already+running+but+is+not+responding
    * You may need to try Firefox Safe Mode
    ** You may need to use '''Safe Mode''' to locate the problem: http://support.mozilla.com/en-US/kb/Safe+Mode
    **Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes '''<u>before</u>''' starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
    ** If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it by enabling '''<u>one at a time</u>''' until the problem reappears. '''<u>You MUST close and restart Firefox after EACH change</u>''' via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.
