Firefox will not open again after crashing

Firefox crashed and brought up the Mozilla crash reporter. When I tried to restart firefox it just brought up another crash reporter and so on. I tried restarting my computer and it did nothing. When I look at the troubleshooting on this website it tells me to look in my menu bar, but I can't even open Firefox to get to that menu. Then it sends me to firefox won't start, and when I click on the part of that page about it crashing, it sends me in a circle right back to the page which told me to check my menu bar. My firefox also recently auto-updated.

Have you tried running Firefox with all add-on disabled (aka. safe mode)? Look in your start menu, there is an entry called "Firefox (safe mode).

  • Firefox will not open up after i restored to default settings

    i recently restored firefox to default settings on my profile on windows xp computer now firefox will not load on my profile but does on my fathers profile.whats up???????????

    Hi jonbeme,
    Thank you for your question. I understand after you reset Firefox, that Firefox will not open up on one of the accounts on this computer.
    This is what happens when Firefox is Reset [https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems].
    To test to see if the problem is the profile, use the Profile Manager to create a new profile. [[Use the Profile Manager to create and remove Firefox profiles]] If the problem goes away, you can then move your bookmarks and other important settings into the new profile.

  • Firefox will not open even after update or in safe mode using windows button + R

    Tried solitions given on site using IE. Firefox will not start at all, did latest update and tried safe mode start.
    Only get box stating it has encounterd a problem and crashed. I only use firefox and have so many bookmarks I really don't want to uninstall and start over.

    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!

  • Firefox will not restore session after crash

    Hello, I am writing because whenever I resume Firefox (like from a crash or restart), it will not reload my previous pages. Instead it will only open a new window and I have to dig through my history to find and reload the pages from my previous session. Firefox is set to remember history and to show my windows and tabs from last time.
    My Firefox version is up to date (although it seems that the version doesn't matter). I have gone into about:config, set browser.sessionstore.max_tabs_undo to 40, set browser.sessionstore.max_windows_undo to 10, and reset broser.sessionstore.resume_from_crash to true. None of that has helped and the latter kicks back to false every time Firefox restarts.
    I have had this issue occur a couple of times in the past, and if I recall, I had to create a new account. If told how to, I can do this again, but I would prefer to get to the root of the problem to prevent this from occurring again (plus I'd hate to lose all my history again). If anyone can help me with this, I'd greatly appreciate it. If you need to know anything else, feel free to ask. Thank you.

    I have finally found a working solution with help from Zzxc.
    You do have to create a new profile, but you can save everything from browser history to ad-ons to dictionary. It even restored the pages I had open in the old profile.
    https://support.mozilla.com/en-US/kb/Managing+profiles
    This shows you how to create a new profile. I left the old one and named my new one as "name" - New Default - "current date"
    http://support.mozilla.com/en-US/kb/Profiles#How_to_find_your_profile
    This shows you how to find all of your information and settings for both profiles. It shows you what file is what (so you can pick and choose), but if you just copy everything from inside the old profile folder and paste it into the new profile folder, you should be gold.
    This seems to have worked for me. If it turns out that I copied and pasted the problem as well, I will post it here, but as of now, everything appears to be in working order. Thanks.

    This was one of my first results on Google searching for this problem, so I thought I should give it a reply now that I can reply from Firefox.
    I'm really not sure what fixed it. One of the pages I read when I was reading about mswsock.dll suggested any issues with it might be caused by spyware or a virus. This seemed likely since I'm running a fresh install of Windows 7 64-bit and had yet to protect it. I downloaded and installed Microsoft Security Essentials, and when I restarted my computer to finalize the install of MSE, Windows updated. When I got back into Windows I immediately started a scan, but the second thing I did was try to open Firefox, which actually opened. So three possible fixes:
    -Merely installing Microsoft Security Essentials. Least likely to have fixed it.
    -Updating Windows. More likely to have fixed it, but still doubtful.
    -Restarting my computer. Most likely to have fixed it. It seems to me that rebooting hasn't been a magic fix since I ran Windows 98, so I often forget to try it, but honestly most of the time that's all a computer needs is to be turned off and on.
    Good luck.

  • Firefox will not open and keeps crashing when I attempt to open it, why?

    I have had several crash reports sent to me by firefox and I have not gone to any sites that I don't normally go to. I want to know why it keeps to this and what I need to do to get this situation fixed. I have sent crash reports and uninstalled/reinstalled this program and nothing has been fixed. I need to use this site so that I can use my bookmarks and do my work.

    How to Enter iPhone Recovery Mode
    1) Connect the USB cable used to sync your device to your computer, but do not connect it to your iPhone.
    2) Turn your iPhone off by holding down the sleep/hold button in the top right corner until the slider appears at the top. Slide it. If your phone won't respond to that, hold the sleep/wake button and the home button together until the screen goes dark.
    3) When the phone is off, hold down the home button and connect the USB cable (which should still be attached to your computer) to the dock connector. The iPhone will turn on and display the Apple logo. Keep holding the home button until the iTunes logo/USB cable appear on the screen. You can let it go then. The phone is now in recovery mode.
    4) If the red empty battery icon appears onscreen, let the phone charge for a few minutes and then restart this process.
    5) When the phone is in recovery mode, a window will pop up in iTunes saying that the phone is in recovery mode and needs to be restored.

  • Firefox will not open again once it is closed

    When I close firefox and then later try to open it I get a message that it is already open. It then says I have to close firefox before I can open a new one for use. This is very messed up because I have to restart my computer and I have other programs running.
    How can I fix this problem?
    Thanks,.

  • Firefox will not open unless I run it in compatibility mode (Windows XP SP 3), run it as an administrator, or launch it immediately after a reinstall (the reinstall thing only works once.) How do I fix this?

    This morning, Firefox crashed. After this, when I click the Firefox icon, the hourglass appears and then nothing happens. Firefox does briefly appear in the task manager when I do this.
    I tried rebooting. I tried reinstalling multiple times. (Firefox will run when I select "Launch Firefox" from the installer. Then the problem occurs again.) I tried safe mode. I have found that Firefox will work if I select Windows XP compatibility mode from the icon properties menu or if I run the program as an administrator. When I do this, Windows asks me if I want a program to be able to make changes to my computer.
    I have noticed that a Windows Error Report is being generated each time Firefox will not open.

    A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

  • I upgraded from 3.6.13 to Beta 4.0 and now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing.

    I uninstalled Beta 4 and re-installed 3.6.13 now Firefox will not open at all I tried to uninstall to start again but it will not uninstall either it does nothing, I have been using Firefox for a long time but cannot resolve this problem can anyone help and give me a solution please. As I use Firefox as my web browser it is very frustrating.
    The fact it will not uninstall appears to be something completely new as nobody I know who uses Firefox has ever encountered this in the past.

    Did you check your security software (firewall)?

  • Firefox will not open after unlocking Sempron

    After upgrading to a new motherboard and unlocking Sempron processor, Firefox will not open. I have tried Firefox (safe mode) and rolled back to a previous version, but to no avail. It worked fine when I ran the Sempron 140 as a single core (even overclocked to 3.17ghz) on Biostar A785GE motherboard. I cannot find a crash ID to link to.

    Maybe you restored to a version of Firefox that crashes or still have a virus problem.
    (irrc some Firefox versions specifically had problems after Windows restores)
    Follow up checking for malware and then try re-installing Firefox. I would also suggest you make a copy of your [[profiles|profile]] including all folders and sub files and put it somewhere safe as it may assist in restoring your bookmarks and information.

  • Firefox will not open at all. I only get the Mozilla Crash Reporter over and over.

    After updating yesterday, Firefox will not open. I repeatedly get the Mozilla Crash Reporter. I've scanned my computer for malware, I've tried to open it in safe mode (it won't), I've completely uninstalled and reinstalled Mozilla, but nothing works. Each time I reinstall, I still get the Mozilla Crash Reporter. The program will not open at all.
