Firefox won't start on computer with Windows x64 installed

Thank you for your help!
I have been having trouble with Firefox starting on my 64-bit Windows 7 computer for months now. It opens the process, but the browser window doesn't appear. Sometimes I have to close the process and restart it multiple times before the browser window opens. The browser process does in fact close when I exit the program, so this isn't the issue.
I have tried everything on the following webpage, as well as other suggestions posted on the Internet to no avail.
http://kb.mozillazine.org/Firefox_:_Issues:_Firefox_Won%27t_Startup
In addition, I have had the exact same profile installed on two separate computers running 32-bit Windows XP and they have never experienced this problem.
I'm really frustrated by this, because I absolutely love Firefox in every other regard. I must, given I'm still using the browser, despite dealing with this nuisance for so many months.

it does not work even in windows safe mode with networking. same issue. if i wait for some time firefox comes but in not responding mode. then a pop shows up with - script: chrome//browser/content/tabbrowser.xml 2123 .

    You need to discard or save to an external disk and then discard some of the stuff we all tend to keep forever (movies, music, pictures, docs, apps no longer used, etc.). A clogged up disk also does not function ideally either.

  • Firefox won't start. Everytime I end the process/close the last window, it keeps getting stuck at about 2500k memory in the task manager. (continued)

    Firefox won't start. Everytime I end the process/close the last window, it keeps getting stuck at about 2500k memory in the task manager. The only way I have to fix it is to change some kind of compability settings or try and access it in a new way, and every time it crashes/closed/computer blue screens that setting will no longer work.
    That is a short term solution, but eventually I'll run out of ways to access firefox successfully. I've tried many solutions, and some worked, but only once. I have yet to find a permanent solution for this problem.

    First please update your plugins to make sure you are up to date. Shockwave Flash player has a newer version 16. In order to better manage the memory that Firefox uses please see these troubleshooting steps: [https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-ram Firefox Uses too much RAM]

  • Firefox won't start after windows update

    After windows Updated my computer Firefox won't start. I tried a clean reinstall two times, won't work. When I tried to start the firefox the first time after booting my computer it comes with the following message.

    I do not see much about coloum 14, but I am guessing this file is stored somewhere and its corrupt. Update.xul suggests that it is the update file. Do you still have this in your downloads folder? There are two places for update and for a clean reinstall:
    [http://www.mozilla.org/en-US/firefox/new/] in a private window will give you a new install or you can choose from here: [https://www.mozilla.org/en-US/firefox/all/]
    This is what the file should look like; [http://hg.mozilla.org/mozilla-central/log/7a2edc5171e6/toolkit/mozapps/extensions/content/update.xul] If you can copy and paste that file from a working browser we can see the issue, but it will just look the same as the error.
    if you can replace the contents of the file locally with what it should look like it will fix the error, but who knows if there are other errors. May be best to delete the updater and save all the profile folder contents.

    You should probably just download the trial version of pse 12 and see if you can live with it.
    Download a free trial or buy Adobe products | Adobe downloads
    That being said, have you tried to install pse 1 on your computer?
    How much free space is on your hard drive?
    Do you have Internet Explorer 10 or 11?
    Pse 1 can run on windows 7 x64, provided certain conditions are met.

  • Bold 9700 won't let me sync with Windows 7 computer using BlackBerry Desktop Software version 6

    I just got a new computer with Windows 7.  I installed version 6 of BlackBerry Desktop Software.  It installed just fine.  When I connect my Bold 9700 to it the software recognizes the phone and has the list of model, PIN, and phone number.  It allows me to backup the device - but not sync it.
    I went to configure my sync settings.  It goes to the screen for me to set the sync options for calendar, memo pad, etc.  I selected calendar.  It asks me which application I'm using and I select Microsoft Outlook (I'm using Outlook 2010).  I choose 2 way sync.  So, up to this point it's working correctly.  But, then when I hit "next" on this screen it gives me an error message - the operation terminated unexpectedly.  I have no clue what's going on.

    I have the same problem and have tried one way sync's, deleting and re-entering the calendar entries made around the time the problem started. If it is a corrupted entry, I can't find it.

  • I just bought a new computer with Windows 7 . How do I start a new account?

    I bought a new computer with Windows 7. I installed itunes, and I downloaded some podcasts. When I try to sync, it begins syncing and then stops.
    Any suggestions?
    Also - is there a way to upload my music from my ipod onto my new itunes?
    Thank you.

    The easiest thing to do is backup your old computer with an external hard drive. Then import all of your files from the external hard drive to the new computer. I just did this about two months ago myself. The biggest problem I had was that it did not keep any of my playlists that I had spent many years developing. However, there is a supposed way to be able to keep the playlists if you do your research on this website (which I did not do first, only after the fact) and follow the steps they guide you with.

  • After reboot firefox won't start. runs in task manager, but won't pop up. reset, safe mode and uninstall/re-install won't help. ok if no reboot.

    win7 Pro. has been running firefox ok. but lately with 25 and now 26, the firefox won't start. I can see firefox is running in task manager. but it just won't pop up.
    if I download it again and install it, it will run, but every time I reboot the system, it just won't run again.
    try: reset, safe mode, uninstall & reinstall, new/clean profile, none of those work.

    There may be a corrupted file on Firefox.<br>
    Please attempt to perform a clean reinstall. <sup>[https://support.mozilla.org/en-US/kb/forum-response-clean-reinstall (More Details)]</sup> This is different than a regular uninstall.
    If a clean reinstall does not fix the issue, please try starting your operating system in safe mode.<br>
    To do so, please do the following:
    #Ensure that your computer is shut down completely
    #Press the power button
    #Tap the <code>F8</code> key repeatedly before the Windows logo and startup screen is displayed
    #Select Safe Mode With Networking for the advanced startup options list
    Please report back with the results of both solutions.

  • Firefox won't start in any form

    I have never had any real problems with firefox not starting in the past, but today I adjusted my internet settings to allow firefox to delete cookies, cache, etc whenever the program was shut down. After doing that, I went to re-open firefox and it would start up, but always "not respond". After 2 or 3 attempts of this with the same result, I restarted my computer and now Firefox will not start at all. The hour glass will pop up for a few seconds, then disappear. The firefox window will not open, but it shows up in the process' list in Win. 7's task manager.
    things I have done:
    Ran Malware check's using 4 different programs (malware bytes, hitman, etc)
    Ran rootchecker
    Ran my norten antivirus.
    Everything that was found (not allot) was removed.
    The Firefox window Does NOT open at all
    I cannot open Firefox's "Safe" mode
    Firefox will not open in Window's safe mode
    I have un-installed and done a clean re-install, and the problem is still there.
    Can someone please help, as I have a few hundred bookmarks I can't lose, and I hate using IE, Safari, Chrome, etc.

    Hello,
    Please see the 'Firefox Previously Worked' section of the support article below.
    [https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions#w_firefox-previously-worked Firefox won't start] (previously worked).
    You need to use the [https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles Profile Manager] to create a new profile. This should allow Firefox to open. You can then migrate your bookmarks, personal data etc across to the new profile.
    I hope that helps. Please let me know if not.

  • Firefox won't start, there is no error message and it is not already running.

    Hi,
    When I try to click on firefox, the little wait icon appears and then disappears. Nothing opens, not even safe mode. I've looked at the "Firefox won't start and there is no error message" help section and looked at my task manager processes. It seems that when I click firefox, it briefly appears on my processes and then disappears. This happened yesterday while I was in the middle of using it. At the same time, my Skype also crashed, which makes me think the two are correlated. The two programs still don't work. The only way that I can open firefox is if I install it all over again with the "launch firefox now" option checked at the end. When I have a firefox window open, I can open other firefox windows just fine. When I close it, nothing opens. Thanks for your help.

    1) Start Task Manager
    2) Open Processes (make the description area large enough to see)
    3) look for a description that says ''firefox''
    4) Select it and press End Process
    '''Now Firefox should work properly.'''

  • Firefox update failed, so I re-installed. Now firefox won't start up at all?

    ''locking as a duplicate of https://support.mozilla.org/en-US/questions/969557''
    So I ran firefox, and it was updating. While updating, firefox crashed for no apparent reason so I had to close it. Afterwards, every time I tried to start up firefox, it gave me the update failed error, followed by a crash less than a second later. I followed some instructions, uninstalling and re-installing firefox (without removing personal data), but now firefox won't start up at all!
    Now what?

    We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
    #Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
    #In that text field, enter %APPDATA% and press Enter. An explorer window should open.
    #From that explorer window, double-click on the ''Mozilla'' folder, then double-click on ''Firefox'' and then on ''Crash reports''. Double-click on ''submitted''.
    #Now, you should see a list of files that contain reports. Go to ''View'' > ''Arrange Icons by'' > ''Modified'' to get the most recent files at the top of the window.
    #Open the most recent 5 files with a text editor and copy the IDs.
    #Paste each ID with '''bp-''' into the reply window on the forums.
    Thanks in advance!

  • Why won't my printer print with Windows 8?

    Why won’t my printer print with Windows 8?
    Have you just upgraded, or purchased a new computer with Windows 8, and now you can’t get your printer to work?  If so, this may help you.  A lot of people have questions about installing their printer on a new OS.  This will help you answer those questions and make sure that you get everything installed. 
    Before You Start
    Before you try to install the printer on a Windows 8 computer, you should check to make sure the printer is compatible with the new OS.  The link below will give you a list of the printers that will work in Windows 8.
    http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03168175&lc=en&cc=us&destPage=document&dlc=en
    If you have upgraded your computer to Windows 8 form another version of Windows, make sure to completely uninstall all of the software for your printer.  It should still print, but to use all the functions you will need to reinstall the software, if it’s available.
    Another thing to consider is how you want to connect the printer to the computer. 
    USB.  You should make sure that you have a USB cable that is no longer than 6 ft. (roughly 2m).  Make sure to connect the printer directly to the computer.  Do not use a USB hub. 
    Ethernet cable.  Make sure you have the network setup, that you have a free cable port on the router, and that you have an Ethernet cable available.
    Wireless.  You should make sure that you have the wireless network setup, and that you have the password for the wireless network. 
     1.     Installing Via USB
    Installing via USB in Windows 8 has become much simpler for HP printer users.  In other versions of the Windows OS you had to start the installation and wait for it to ask you for the USB connection.  If you didn’t, you would have to uninstall the printer from the Printers/Devices folder, and then start the install.  In Windows 8, that will not be a problem.  If you plug the printer’s USB cable in and then install the printer’s software, it will still work.  Now for in depth instructions on installing the printer via USB click the link below.
    http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03460670&tmp_task=solveCategory&cc=us&dlc=en&la...
    2.     Installing Via an Ethernet Network Connection
    For an Ethernet network connected printer the install is amazingly simple.  All you have to do is connect the printer to the network.  Once you have that done, Windows 8 will automatically install the drivers for you.  Then, all you have to do is install the rest of the software, if it’s available.  It’s really that easy.
    http://www8.hp.com/us/en/support-drivers.html
    3.     Installing Via a Wireless Network Connection.
    For a wireless network connected printer the install is amazingly simple as well.  All you have to do is connect the printer to the network.  Once you have that done, Windows 8 will automatically install the drivers for you.  Then, all you have to do is install the rest of the software, if it’s available.  It’s pretty much the same as an Ethernet install, just wireless.
    http://www8.hp.com/us/en/support-drivers.html
    Alternate Install Methods
    With Windows 8, many printers’ drivers are installed with the OS.  These are known as InOS drivers, since they come built into the operating system.  If you have one of those printers, all you should have to do is connect it to the computer via USB, or connect it to the network via Ethernet or wireless.  Once you have that done Windows will handle the rest.  There are alternate methods of installing your printer if the normal methods are not working for some reason.  You can install the printer either using the Printer Install Wizard, or through Windows Updates. 
    Printer Install Wizard:
    http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02681060&tmp_task=solveCategory&cc=us&dlc=en&la...

    http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03460648&tmp_task=solveCategory&cc=us&dlc=en&la...
    Note: The Laserjet drivers for the Asia-Pacific and Japan won’t be released until a later date.  Check the support site linked below for driver availability.  I will update this post once they become available.
