  • Firefox won't open, but also apparently won't close, and so won't uninstall--help!

    I'm using Windows XP, need to use Firefox as browser for work. I clicked on the icon which doesn't open, tried to run it in safe mode, no go. Can't bring it up, can't remove it through the control panel add or delete programs option. Can't uninstall it: setup message advises to close Firefox, but I can't see where it might be open. Can't download a more recent version, because I get the same message about closing open Firefox windows. please help.
    This has been consistent.

    Do a clean (re)install:
    * Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
    * 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 [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] (not in the Firefox program 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.

  • Firefox won't open, but the process stays in the task manager until I end it

    I've tried everything that has been proposed before by you guys and I'm hoping you've found a solution by now. I've tried re installing, allowing Firefox through my firewall, and running it as administrator. I still double click on the icon and nothing happens other than the process showing up in the task manager.

    Hello,
    Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
    '''Note:''' You might want to print these steps or view them in another browser.
    #Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
    #After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
    #Delete the Firefox installation folder, which is located in one of these locations, by default:
    #*'''Windows:'''
    #**C:\Program Files\Mozilla Firefox
    #**C:\Program Files (x86)\Mozilla Firefox
    #*'''Mac:''' Delete Firefox from the Applications folder.
    #*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
    #Now, go ahead and reinstall Firefox:
    ##Double-click the downloaded installation file and go through the steps of the installation wizard.
    ##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
    Please report back soon!
    Hope this helps!

  • Firefox won't open on WIndows vista & it has worked for years.

    Used task manager, closed firefox.exe & restarted, worked twice & I disabled Norton Toolbar. Now firefox won't open. I uninstalled firefox and redownloaded it & still won't open. Search for the Profile Manager doesn't show anything.
    I did download an HP update yesterday. I am using windows explorer for this since I have toahve that on my computer to access some citrix programs

    Right mouse click the iTunes icon and select "Run as Administrator"

  • Firefox does not open, but instead gives the error message, "Failed to read the configuration file." It has worked in the past, but not now.

    I REINSTALL 10 TIMES SO DON'T TELL ME THAT!!!
    I'm piss because i need firefox working again so i can finish reseaching my speech in 5 days.

    Which files do you have in the defaults\pref folder in the Firefox program folder?
    *(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
    *(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
    See also "Other solutions":
    *http://kb.mozillazine.org/Preferences_not_saved
    Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
    Download a fresh Firefox copy and save the file to the desktop.
    *Firefox 22.0: http://www.mozilla.org/en-US/firefox/all.html
    Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
    *Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you lose personal data like bookmarks and passwords from profiles of other Firefox versions.
    Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
    *(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
    *(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"

    Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

  • Tried to use Restore to return to pre-Firefox4 but now Firefox won't open and won't uninstall.

    After trying to maneuver the new Firefox 4.0 for a while and giving up, I wanted to go back to the 3.6.1.6 version. I used the Restore feature to try to go back to the pre-Firefox 4.0 dowload. Since then, Firefox won't open. I have tried to uninstall Firefox 3.6.1.6, which is listed in my installed programs in the Control Panel, but it doesn't do anything. At this point I don't know what to do. I want to re-instate the 3.6.1.6 version on my computer. Thanks.

    You're in a bit of a pickle here because you can't use System Restore to revert to 3.6.16. You probably now have version 1.9.2.x which is in part, files which were not removed when you installed FF4
    What you can try and do is use System Resore to undo the last restoration which should take you back to 4.0 again. If that fails, see this article: http://kb.mozillazine.org/Uninstalling_firefox
    If the undo restoration is successful, do the following to revert to 3.6.16
    Go to [http://www.mozilla.com/en-US/firefox/all-older.html Download Firefox v3.6.16] and download it to the desktop. If necessary, download the file with IE8 and choose to save it to your desktop when you see the prompt.
    Then go to Add/Remove Programs, scroll down to Mozilla Firefox and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box).
    Then reboot and delete the folder called '''Mozilla Firefox''' at this location: ''C:\Program Files\Mozilla Firefox''
    Finally run the installation file you downloaded to the desktop earlier.
    Your bookmarks, customizations etc., are maintained in a different location and will become available to you again once you complete the installation.

  • Firefox won't open when I click on the icon. I've tried uninstalling so that I can reinstall, but it says I have to close firefox (which isn't open), so I'm stuck.

    The problem: Firefox won't open when I click on the program.
    Solutions tried: #1) I tried to uninstall the program so that I can download it again, but the screen shows the message "firefox must be clsoed.. to proceed with installation". However, firefox is not open.
    #2) I tried to download firefox, thinking that possibly it would update and solve the problem. However, I get the same error message that "firefox must be clsoed.. to proceed with installation" Problem is that firefox is not open.
    I've done a screen shot, so you can see that I do not have the firefox browser open.

    Thanks for the reply. I tried repairing the permissions (as well as several other things like deleting the Finder preferences file), but no dice.
    Given that the problem cropped up right after updating OS X on two separate machines, it's looking to me like it's just a bug that needs squashing at this point.

  • Installed Inbox Dollars toolbar, now Firefox won't open- someone responded, but I forgot to bookmark the answer, now I can't find it

    I installed Inbox Dollars toolbar, now Firefox won;t open at all. Using OS 3.6.8. Someone responded but I forgot to bookmark the answer, now I can't find it.

    Will whomever posted the original reply, repost it today if possible. I am going tomorrow morning to try to have someone do this for me, and now I can't find what you said to do.
    Thanks!

  • Grab app. is present but won't open or work

    It's technically in the memory, but it won't open or work while a DVD is playing. What is going on???

    Am I the only one who has this problem???

  • Firefox won't open links from Mac Mail

    Like everyone else Apple Mail links will not open in Firefox if it is already open. Clicking a link brings FF to the front but no page loads. Links work if FF is not open. Links work if command is pressed whilst clicking the link (opens in new tab in background).
    Problem occurred after 32.0.2 update, it appeared to briefly resolve itself after 32.0.3 update, but stopped (I think) on next reboot.
    Have monkeyed around for ages with different combinations of default browser and rebooting.
    Will abandon FF and go back to Safari if this isn't sorted soon - shame.

    I just want to link to these earlier threads so you don't get a lot of duplicate suggestions that have already been covered there:
    * [https://support.mozilla.org/questions/1018542 Firefox won't open email links after update to version 32]
    * [https://support.mozilla.org/questions/1023202 No tab opens when I click on a link if any Firefox window is already open]
    (There might be others, but those are the ones I've seen)
    Work is proceeding on [https://bugzilla.mozilla.org/show_bug.cgi?id=1017595 Bug #1017595 – Links from external applications sometimes fail to open when Firefox is hidden] but as you can tell from the title, this is focused on the problem of Firefox not coming out of hiding from the dock or coming out of hiding but not loading the page. If this also occurs when Firefox is not hidden at all, there may be a secondary issue. But hopefully solving the one will solve the other. Unfortunately, I don't know whether it will be in time for Firefox 33.

  • Mac won't open pages in browsers. Chrome and Firefox won't open any pages - Safari will only open a selected few.

    I've had some strange browser issues, with Conduit being added to Chrome (which I've tried to remove via the browser settings). Chrome will open my Gmail account but no ther pages. Firefox won't open anything. Safari opens a few pages (this forum thankfully) but is very selective.
    Google is returning results to me via Google.es rather than Google.co.uk
    I can use all browsers freely on other devices on home network (although Google.es has popped up on my iPhone now). I've run anti-virus software which hasn't picked up any problems. I've tried uninstalling Chrome and Firefox, but am unable to do so.
    Any help or guidance would be really, really appreciated.
    I'm running the most recent version of Mavericks on  2012 iMac.

    Hi,
    First of all click Safari/Reset Safari, next click Safari/Preferences/Extensions and turn off extensions. The re-test
    If the problem persists, try using safari in safe mode:
    Use this link to see how to do this:
    http://support.apple.com/kb/HT1564
    If Safari works ok in safe mode, then your problem points to something 3rd party related.
    Have a look at this:

    I hope this helps

  • Firefox won't open because it says it is already open when it ain't

    Firefox won't open because it says it is already open. It appears Firefox is operating in the background. Tried to remove it but we get the same message to log out of Firefox. For 10 years we have been using McAfee with all features but it does not detect any virus or malaware etc. It appears it might be a malaware problem but even using all the latest Microsoft fixes hasn't helped. We used Vista Business Professional with all the latest service packs updated. We use the latest version of Firefox as of up to around 3 weeks or so ago when this issue first appeared.

    I suspect you need more expert help but here are a few things you can try.
    If you can't open Firefox(double click on Firefox desktop icon) try Safe Mode - Hold down the Shift Key as you double click on the icon>don't check anything on the page that opens>continue. If Firefox opens and works in this safe mode go to Add-ons> Extensions and look for "Ask". Then look at Add-ons >Plug-ins and again look for "Ask" . Remove, delete,disable any Asks. If you do remove any, close Firefox. And try again in Normal Mode.
    The Ask website has detailed instructions for removal but you need to find it on your computer and have your computer in working order.
    If there is no sign of Ask and Firefox is working well in Safe Mode you should work your way through this -
    https://support.mozilla.com/en-US/kb/Troubleshooting%20extensions%20and%20themes
    Eventually you might need to grapple with About:Config and even your Windows Registry but I would recommend a complete uninstall and re-install before that. Unfortunately that often doesn't work.
    That all sounds very daunting but taken step-by-step you might get lucky early.

  • Firefox won't open new tab

    Firefox won't open a new tab. It opens links on a new tab but if I try to open a new tab manually it does nothing. It was fine yesterday but not today.

    That can a problem with the Ask<i></i>.com toolbar (Tools > Add-ons > Extensions)

    I had the same problem when i dl-ed a new anti-virus softward, but what I did help me reconnect Firefox again!
    Here is what I did,
    Go to open firefox browser-->option-->advanced-->network-->settings-->and change it to auto-detect proxy settings for this network!
    It worked for you, hope it will work for you too =)!

  • Updated to 4.0 version and when it loaded I got 4 identical icons on my desktop. I went back in time on my computer and now Firefox won't open.

    Updated to 4.0 version and when it finished loading I got 4 identical Firefox icons on my desktop. I went back in time on my computer to go back to an order version and Firefox won't open or is very slow to open.

    Do a clean (re-)install:
    * Download a fresh Firefox copy and save the file to the desktop.
    * Firefox 4.0: http://www.mozilla.com/firefox/all.html
    * Firefox 3.6.x: http://www.mozilla.com/en-US/firefox/all-older.html
    * Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
    * Don't remove personal data if you uninstall the current version.
    * 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.
    * It may not be necessary to create a new profile, so first try if it works with your current profile and if not then create a new profile.
    Your bookmarks and other profile data are stored elsewhere (not in the Firefox program 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.
