  • Firefox does not start after the places.sqlite opening in Notepad

    Firefox does not load again. I tried to create a large folder of bookmarks, but I wanted them to hide so I tried to be clever and create a copy of my current places.sqlite who had no bookmarks added and moved elsewhere, then I added bookmarks and once that replace the current places.sqlite then I created a copy of this and put it elsewhere for more security and then I replaced it with the first places.sqlite I had copied. I had to go through that much trouble because for reasons, I was unable to delete the bookmarks by right-clicking and selecting delete. I had already tried to open places.sqlite in Notepad and since then is when it started to happen. I tried to reset the file extension type, or rather detached, but I can't figure out how.

    Can someone tell me what to do or where it is that I was wrong?

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

    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 do NOT delete personal data when you uninstall Firefox which removes all Firefox profile folders and you lose your data.

    If you keep the problems, and then create a new profile.

    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 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.

  • Firefox does not start (not safe mode), but uses the CPU

    I have the latest Firefox 25.0 (and the last Flash 11.9.900.117) on Windows 7 and the following behavior is reproducible. It started not too long ago.

    At first when I launch Firefox, nothing appears no matter how often, I restart. I see in the list of the process firefox.exe to 25% of the CPU, 2 x FlashPlayerPlugin_11_9_900_117.exe (CPU 0%) and plugincontainer.exe. No matter how many times I killed all of them, would not restart Firefox.

    The following also not help in this situation:

    • Starting in normal safe mode: Firefox opens a window but immediately freezes and does not respond. The process list shows the same process even if I find the unexpected FlashPlayer.
    • Disable plugincontainer: same results (just without plugincontainer.exe)
    • Uninstall Flash: Same results (just without FlashPlayerPlugin)

    The following can start Firefox only once:

    • Starting in SafeMode but select "Reset Firefox": Firefox does not start right away, however. Nothing happens, and you have to kill the process. However the very next time you launch Firefox in the normal way, it works fine (but it shows FlashPlayerPlugin.exe in the list of unopened Windows process despite the tab). Unfortunately, after closing Firefox the process (Firefox, FlashPlayerPlugin) are not deleted. I kill and the problem with Firefox do not leave reappears.

    In case you use "clear history of Firefox closing:

    • do not delete Cookies

    Note that compensation "Preferences of Site" clears all exceptions for cookies, images, windows pop up, installation of software and passwords.

    Use "Firefox > output" (Windows: Firefox/file > quit;) Mac: Firefox > quit Firefox. Linux: Firefox/file > exit) to close Firefox if you are currently doing by clicking on the X close in the title bar of Firefox.

    Create a new profile manually (and not via the reset) as a test to see if your profile is the source of the problems.

    See "create a profile":

    If the new profile works then you can transfer files from a profile in the new profile, but be careful not to copy files corrupted to avoid transporting on the problem.

  • Firefox does not open, and when I try to use the "run", it says that the file has been moved, etc. I use Windows 8 and I can't lose my favorites. Help?

    Firefox has been great to work on my computer for months and then suddenly he could not load pages. So, naturally, I restarted my computer, but when it restarted Firefox does not open. The icon lights for a bit as usual, then it fades and never actually opens. When I try to use the "run" command, I get this error:
    "C:\Program Files\Mozilla Firefox\ refers to a location that is unavailable. It could be on a hard drive on this computer or on a network. Make sure that the disc is inserted correctly, or that you are connected to the Internet or your network, and then try again. If it can't be located, the information may have been moved to another location. »
    I also tried the same thing for the file in the x 86 folder, but it gave the same error and I went and looked for the files in the given location and they were there.
    Firefox is not to fall down, so he isn't there an other error message, I can give you.
    The things that I had my favorites are really important, I can not lose those, but I am fine with anything else have to re-installed, etc..
    Help please?

    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 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. 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 display some things, for example the box for this text, but only on a logon - how to fix?

    Firefox does not appear certain things. For example, the area around the text, the above options (bold, italic, type inserting a link - I can see what they are just by moving the mouse pointer in the approximate area and reading the small text that appears). Other things, that it does not appear - the word 'Google' when I opened the page of search engine, icons in eBay. On eBay, when I log in, the words "sign in" appear as 2 different fonts superimposed on one another, both in black. In Internet Explorer, it appears as white text on a blue background and is quite readable. Now that this description has reached the length where the scroll box is needed, the scroll box appeared, but there is still no box around the text. Underneath, there is a box to a drop down menu ("what happened"), but not for "began when this" or "troubleshooting information. I don't know where to put the cursor to find these areas because it turns into a bar I when I'm in the right place. The really funny thing is: only, it has that way about my logon - works of fine wife! (Work that one!) It all started when I was running version 3.8.5 (I think it was). I downloaded version 4 hoping he could solve the problem, but it didn't. I uninstalled and reinstalled, but the problem is still there. I have several months now (I think - at least 2 months) while the computer was turned off and rebooted several times, without effect.

    Looks like a broken profile. Back up your bookmarks, create a new profile , and then import your bookmarks back in. Let me know if you need additional assistance.

    Thank you!

  • Firefox does not open a new, secure login page, on the site of my Bank

    Site Web of my Bank opens a new, secure, log in page from a link on its home page. When I click on this link to do, nothing happens. No window opens and Firefox does not all messages as to why. He used to work, but stopped in the past two months. I don't know if it something in my settings or not. I also use the Flock browser - which is based on Mozilla code and the link works in this browser. Settings in both browsers seem to be the same.

    URL of affected sites

    I get the login window in Firefox.

    It uses javascript to open the window. Try hitting control + F5 - that recharges all of the scripts in case one is corrupt in the cache.

    You have additional modules that may be blocking scripts? Adblock Plus, no Script...
    If so try to disable them.

  • 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.

    This has happened

    Each time Firefox opened

    I closed the navigation bar to make more space on the screen and I could not re - open.

  • 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:


    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.

    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
    "C:\Program Files (x 86) \Mozilla" 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 and I don't see anything that looked like in "virtualization" settings, so I guess that does not apply to me. "

    If you have any ideas, I had appreaciate that your expertise!

    Hello arcandl, at the launch of the firefox is not after you double-click the shortcut, it is sometimes also a sign of active malware on a system.
