Firefox does not open on Windows 10 no matter what I try. Is there something that can solve this problem?

I tried to contact support Windows 10 and they were useless. It was working fine all day and does not open all of a sudden.

This sounds like a file in your Firefox profile may be damaged or not valid. To check if this is the case, you will need to create a secondary Firefox profile and test to see if you can open Firefox with this profile.

This can be done using the Manager of profiles for Firefox which can be downloaded from Mozilla's FTP server. There is no installation required, the program is contained in a ZIP file. Simply extract the ZIP file and run the executable file inside.

How to create a second profile Firefox, please see this support article:

Note: Do not delete the old profile because if it is damaged, you may be able to recover your bookmarks and settings. For more information on how to proceed, please read the article of the recovery of data from an old profile .

    I've never tried it myself, but the forum has a series of measures for a "clean reinstall" Firefox. Even if you do not delete the record of your personal settings (AKA profile) during this process, a backup of this folder is always a good idea in case something goes wrong.

    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.

    Please report back to see if this helped you!

  • Firefox does not open more than one window, only opens new tabs. Firefox does not open in safe mode.

    Firefox does not open more than one window at a time, and then opens only new tabs. When asked to open the link in a new window - nothing happens, no error message or the page appears. Otherwise, it works great, but no new firefox window cannot be opened menu or the mouse. I tried to reinstall firefox several times, which did not help.

  • 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.

  • Firefox does not open after the update. Cannot open the profile technical, even when you use the directory in cmd line path

    I'm using Firefox on a Windows 7 computer. Firefox does not open after the last update. I read the help articles and it seems that I need to create a new profile because my settings were probably corrupted. I'm unable to open the profile technical, even when you use the directory in cmd line path. I tried the following commands in the command line:

    Firefox Pei

    Nothing happens with every order.

    I am also running Norton Internet Security. I read a help of virtual navigation features Re article that can cause a problem. The article says to check the setting of virtualization in the internet security software and to clear the virtual cache. I went through all the menus of settings in Norton Internet Security version 21.6.0.32 and I don't see anything that looked like in "virtualization" settings, so I guess that does not apply to me. "

  • 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.

  • I don't have a navigation bar and firefox does not open in safe mode to return to the default configuration. Does not work reinstall. Any help please.

    I have no navigation bar since I closed it to have more space on the screen. It will not re - open. Firefox does not open in safe mode, but immediately opens in normal mode with the new configuration incorrect, so I can't reset to default configuration. I deleted Firefox and re-installed and it always opens with the same faulty configuration. Why doesn't Firefox give me the safe mode dialog box, why can I not re - open the navigation bar, and how I can do those two things, please? Firefox is currently unusable for me without a navigation bar with no access to the default settings in safe mode. I can't search the extensions that I use since I have no navigation bar to go to tools, modules, Extensions.
