Firefox does not open on my computer

For some time last night and today (11/18) Firefox does not open when I click on the quick link to my office. I tried to add another profile by clicking on start/run/firefox.exe, but it does not work yet. What would be the next step?

Error messages appear when you try to open Firefox?

In the Task Manager, is the firefox.exe process running?

Some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files, and then reinstall Firefox. Please follow these steps:

Note: You can print these steps or consult them in another browser.

  1. Download the latest version of Firefox from http://www.mozilla.org office and save the installer to your computer.
  2. Once the download is complete, close all Firefox Windows (click on quit in the file menu or Firefox).
  3. Remove the Firefox installation folder, which is located in one of these locations, by default:
    • Windows:

      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x 86) \Mozilla Firefox
    • Mac: Delete Firefox in the Applications folder.
    • Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
  4. Now, go ahead and reinstall Firefox:
    1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
    2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

The report please come back shortly.

    Do a clean reinstall and delete the program folder before Firefox to (re) install a new copy of the current version of Firefox.

    Download a new copy of Firefox and save the file to the desktop.

    If possible to uninstall your current version of Firefox to clean the Windows registry and settings in the security software.

    • Do NOT remove the "personal data" when you uninstall your current version of Firefox, because this will remove all profile folders and you lose personal data such as bookmarks and passwords including data profiles created by other versions of Firefox.

    Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

    • (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
    • (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.

    Your bookmarks and other personal data are stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but make sure that 'delete personal data' is NOT selected when you uninstall Firefox.

    If you keep problems also create a new profile.

    Please include more information, such as your operating system (Windows?) and the version, more exactly what is happening when you try to start Firefox. The information provided in a recent Firefox crash report, if any, can also help. See Firefox plant - troubleshoot and prevent assistance fixing crashes under help in setting this crash and post any crash report IDs recently (they start with bp - )

So that allows you to start Firefox, but if the problem comes back after the computer restarts, you should make another "clean reinstall" and then resolve your plugins by disabling all, as suggested by the troubleshoot and diagnose problems of Firefox article.

  • Firefox does not open. Hangs during 'connection '. Inadmissible even in the process of closing via the Task Manager.

    Yesterday, Firefox does not open. It hangs at the "stage of connection." For hours. It doesn't even turn off using the Manager of tasks for applications or processes, and it hangs almost all other applications. I thought that I managed to save a Word document opened yesterday - it looked like a slow, but normal save during the shot of Firefox, but the document was empty when I restarted my computer.

    Although my machine is not pentium 4 in service, I tried to start by using the configuration of Windows XP/M, I downloaded and re-installed (above) the existing version, I checked that no process of Mozilla turned before trying to start Mozilla and tried to create a new profile. Absolutely no success. Every time (dozens), I tried to start Firefox, I had to force a difficult to exit the application shutdown. I now have this marking Firefox in my taskbar, because I keep forgetting and hit by reflex.

    I am running version 11.0 (at least that's what I just downloaded - I am not positive of what I was running yesterday). My system is Windows 7 Home Premium, Intel Core i3 2.4 gHz, 4 GB of RAM, 64 bit OS.

    Next option is to restore to an earlier version. If this does not work, I uninstall and start again from scratch.

    I disabled AVG (antivirus free 2012) for 10 minutes, open Firefox and browsed a bit. Close the browser, whereas the temporarily disabled AVG activated itself again and restarted Firefox. Now, it connects perfectly - several times faster than prior to this incident (I have installed v 12.0; previous version was 11.0). I use the Microsoft Firewall, if while the firewall solution suggested above has not worked, he put me on the right track.

  • Firefox does not open in full screen on the task bar and I have to go over it to see the web page.

    Firefox does not open in full screen on the task bar and I have to go over it to see the web page.

    Firefox window is sometimes "off screen" somehow. Often, you can force it to appear on the screen by right clicking on the thumbnail image just above the taskbar and choose expand. Does it work?

    A possible cause for this is that the file that stores the positions and sizes of window is corrupt. You can delete this file and Firefox will return to standard window resizing.

    #1 method: If you can get a zoomed window:

    Open the settings folder (AKA Firefox profile) current Firefox help

    • button "3-bar" menu > "?" button > troubleshooting information
    • (menu bar) Help > troubleshooting information
    • type or paste everything: in the address bar and press Enter

    In the first table of the page, click on the view file"" button. This should launch a new window that lists the various files and folders in Windows Explorer.

    Leave this window open, switch back to Firefox and output, either:

    • "3-bar" menu button > button "power".
    • (menu bar) File > Exit

    Pause while Firefox finishing its cleanup, then rename xulstore.json to something like xulstore.old. If you see a file named localstore.rdf, rename this to localstore.old.

    Launch Firefox back up again. Windows normally appear again?

    #2 method: If you can not get a Firefox window for all:

    Close Firefox by right clicking the icon in the taskbar > close all windows.

    Using the Run dialog box (windows key + R) or the start search bar menu type or paste the following and press Enter to drill down to the profiles folder:

    %APPDATA%\Mozilla\Firefox\Profiles

    Here you can see a folder - in this case, double-click that - or more than one case - in this case, double-click on in what looks like the most recently updated.

    Scroll down and rename xulstore.json to something like xulstore.old. If you see a file named localstore.rdf, rename this to localstore.old.

    Launch Firefox back up again. Windows normally appear again?

    Then, to re - light bars, you can use one of the following methods to view the list of the toolbar, and then select the desired bars it:

    To activate the menu bar, toolbar bookmarks or other bars, click it in the list.

  • After you download the update of Firefox 25.0.1 Firefox does not open. Help! Thank you!

    I downloaded the update for 25.0.1 and he ran. Instead of restarting, I stop the laptop (Vista Home SP2, 64-bit).
    When I started the laptop again, I tried to open Firefox, but Norton Internet Security leader Insight could not check the update as a reliable file and did not allow for Firefox open.
    I tried to disable file Insight but got the same results.
    I ran Live Update to update Norton Internet Security and then tried to open Firefox again.
    This time this Norton Internet Security displays a message saying that updater.exe wasn't careful and eliminated.
    When I try to open Firefox, Norton now detects Updater 25.0.0.5046, said he trusted, but Firefox does not open.
    I want to save the history if possible.
    How can I get Firefox to work with recorded history again?
    Thank you!

    Hi iamjayakumars - I was not able to create a new profile, because the Profile Manager does not open. A message from Norton seems "Updater.exe is sure.", but nothing else would happen.
    But - the links you sent were very helpful, and I was able to solve the problem by making a UN-installing and then re - install Firefox:
    1. backup of the profile.
    2. download the installer of Firefox from Mozilla.org with another browser.
    3. un-install Firefox from the control panel (ensuring "Delete my personal Firefox and customizations data" was NOT selected.)
    4 reinstall Firefox.
    Firefox starts successfully with all my old settings and all the tabs I had open the last time it was used appeared as I had hoped.
    Thanks a lot for your help!
