  • Firefox won't stop running unless I go into task manager and end process

    when I shut down firefox and then later try to start it again a box comes up that says it is already running but it won't come on. So I have to go into my task manager and end the process before I can start it again. How do I solve this problem?

    That is "hanging at exit". You can ignore the first part, since you already know how to do that.

  • When I close firefox (in windows 7), it doesn't fully close, I have to go to the task manager and end process before I can open it again.

    Every time I try to open firefox, a window pops up saying that another instance of firefox is already running (still open from the last time firefox was open) and that another instance can't be opened. To solve this, I have to go into task manager and end the firefox (32) process. I think this started happening after getting the newest version of firefox a couple weeks ago. My computer is a month-old thinkpad with windows 7 64 bit.

  • When I close firefox it doesn't close. I go to reopen it and it says that it is already running. I have to use task manager to end process to close it before i can log back on.

    After browsing and I close Firefox it appears to close.
    However when I go to reopen it later I get a message that Firefox is already open and I need to close it. The only wany I can close it is by using Task Manger to end process.

  • I use Firefox to access the internet-but when I go off the internet but don't shut down, then go back on Firefox it won't open because "it is already running". Task Manager doesn't show that it is operating so I can't shut it off. What to do?

    It is in the question but to repeat.
    1. When I go online I use Mozilla Firefox
    2. While I am doing other work, I usually close the internet.
    3. If I go back on the internet and click on Mozilla it won't come up, stating that "it is already running".
    4. Despite that, when I open Task Manager, it doesn't show that it is running so I can't shut it down or open it.
    5. If I log off or shut off the computer, then after I log in or reboot the computer, I can open Mozilla.
    Thanks from a Mozilla fan.

  • Firefox won't open PDF files after I removed older version of PDF-xChange Viewer and installed the lastest version of PDF-xChange Viewer. MS Explorer which I am now force to use works OK. I have checked the Applications window in Tools/Options and it l

    Firefox no longer opens PDF files. Explorer works OK. I have checked the Applications window in the Tools/Options and it says I am using PDF-xChange viewer....It just does not do anything. I get the message in the Download Error window which says...."could not be saved, because you cannot change the contents of that folder. Is the same error which I get when I attempt to open a PDF file on a webpage using the Firefox browser....Explorer works OK so I am now forced to Explorer to read PDF files via a browser.
    == This happened ==
    Every time Firefox opened
    == After removing a old copy of PDF-xChange Viewer and updating to the last version

    The error message suggests that the file (pdf) that you're trying to download cannot be saved in the folder Firefox tries to save it in.
    This can be due to several things - it could be a non-existing folder (could be a problem with the updated application), the hard drive could be too full to store the file (less likely if you can generally surf the net without error messages) or it could contain an error.
    To complicate things a little further, it seems to me that you have (at least) 3 different PDF-handling plugins in Firefox from different programs:
    PDF-XChange Viewer Netscape Gecko Plugin
    Adobe PDF Plug-In For Firefox and Netscape "9.3.2"
    Zeon PDF Plugin For Mozilla
    This shouldn't matter too much, thou, as it will most likely simply use either the latest installed or the first one it finds when looking up associations for files of type 'pdf'.
    First, in Tools > Options... > tab General > section File download, select "Save files in" and Browse your way to a (non-writeprotected!) folder on a drive where you're certain there is enough free space - like the Desktop folder to make the files end up on your Windows desktop.
    Second, under Applications as you mention yourself, find all document types related to PDF files, and set these to one of the programs. Check the entire list to be sure there isn't one hiding under one of the other programs' document types (Adobe Acrobat document, PDF X-Change and Zeon).
    Restart Firefox, and try opening a PDF again.
    If it fails once more, try changing the documents again to one of the other programs, like "Use Adobe Acrobat (in Firefox)".
    If it STILL fails, change it to simply "Save file". Then you can simply browse your way to the download folder with Windows Explorer, and doubleclick the PDF file to see which program actually handles PDF files as default on the machine, and if it works properly.
    If Firefox flatly refuses to save the PDF files in a folder which you're certain both exist and has space for the file, some (probably security related) program is most likely interfering with Firefox, preventing it in storing PDF files on the system.

  • Sometimes I have to use Task Manager to 'end process' Firefox before I can open it (not shutting down cleanly from previous use)

    Question seems self-explanatory

  • I close Firefox and then try to shut down my computer, but Windows says that Firefox is still running. It does not show up as running in Task Manager. I have uninstalled and reinstalled several times with same result.

    I have also had problems starting Firefox. I click the icon and nothing happens. That problem is intermittent. The Windows message that Firefox is still running after I have closed the Firefox browser keeps occurring and I do not know how to remedy this.

    The one thing that is locking up fire fox is the plug ins. You have to check to see if a plug in is locking up firefox first of all.
    To see the processes press : CTRL+ALT+DEL. then click the tab marked "Processes" Then look for Fire Fox and click on it. Click the Yes button when the warning box show up.
    Then do the say for "Plug-in Container" I believe that is called.
    this is because all ads are now flash ads or video ads. They lock my computer up all the time.
    When the CTRL+ALT+DEL are pressed. Keep this minimized and you can see if your computer is running at 100% memory near the clock. If the box is totally green, you are running a lot of programs on your system. Check the processes and find out what is not needed. Also watch your virtual memory. Rule of thumb is 1.5x total memory.
    Then now it would be able to shut down the computer the right way.
    Hope this helps you out.

  • I've had issues with Firefox hanging in memory even if I try to remove it using the Windows task manager's "End Process" button. My only alternative is to force a reboot on my PC.

    Since upgrading to Firefox 7.0.1 I've noticed the abovementioned problem. I usually have a couple of app tabs with GMail information on them (two different e-mail accounts, one of which is just the contacts page and the other is the inbox and one tab with a GMail calendar for one of the accounts) and my home page, which is Google News. While I cannot say for certain that it is related to multimedia streaming, it does appear to happen after I play some kind of video file like the videos for The Daily Show with Jon Stewart. My O/S is XP Pro SP3, my PC is a Dell Inspiron 700m w/2GB RAM. The Add-Ons that I have, as far as I can remember, are AdBlock Plus, Tab Mix Plus, WOT Safe Browsing Tool, and Download Statusbar along with the usual Java stuff. My Adobe plug-ins are always updated whenever I get an update message.

  • Firefox does not "close" when closed under Windows 7; Task Manager must be used to "End Process." How do I close Firefox and reopen it without getting a "Still Running" error message?

    Even though Firefox has been updated multiple times (currently using Ver. 3.6.13) since I started using Windows 7, I am still unable to totally close it from the toolbar or taskbar. Firefox does closeout on the screen but apparently continues to run in the background. If I open Firefox at a later time, I get an error message stating that Firefox is still running. I then have to go Task Manager to "End Process." Electing to do so allows me to restart Firefox. I never had this problem with Firefox when using Windows XP and I never have this problem with any other software under Windows 7.

    System: Toshiba Portege M750, Vista 32-bit SP2,4GB RAM
    I've been using Firefox up until last night when I shut down. This morning I did a cache cleaning using CA Internet Security Suite, ver 7.0.0.117. Firefox will not open a window, though it does show in the Processes list of Task Manager.
    I've uninstalled and reinstalled ver 6 from the web twice with the same results.
    Firefox has had a tendency to hang (never finding a new website, i.e. busy icon revolves endlessly) when left open over several hybernation cycles.
