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:

  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.

  I have no navigation bar since I closed it to have more space on the screen. It will not re - open.

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.

• 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.

• Firefox does not save previous seession Web sites, even if the box is checked.

  I recently upgraded to Firefox 5.0. I'm having two problems since the upgrade:

  1 Firefox saves more websites that I left 0pen from a previous session even if the box is checked to do. In addition, I am never given the option to 'restore previous session' in the menu background. It is always 'ghost' out and cannot be selected in the menu.

  2. when I open Firefox, I use a shortcut or go to the Web browser in any other way, multiple instances are open automatically. I suspect that the number of instances is the number of tabs that I left open in the previous session, but I'm not sure about this. They all open to a blank page, however and do not open Web sites that have been assigned to each tab in the previous session.

  Thank you for your help.

  You can check if the session restore is activated [1].

  It is possible that there is a problem with the sessionstore.js and sessionstore.bak files in the Firefox profile folder.

  Delete the sessionstore.js file [2] and sessionstore.bak in the Firefox profile folder.

  • Help > troubleshooting information > profile directory: opens showing the file
  • http://KB.mozillazine.org/Profile_folder_-_Firefox

  If you see files sessionstore-# .js with a number in the left part of the name as sessionstore - 1.js then delete those as well.
  
  Delete sessionstore.js will cause App Tabs and groups of tabs and all tabs open to get lost, so you will need to create them again (take note or bookmarks).

• Firefox does not open a link after the first; Open ok in new tab front.

  In the last week or two, for reasons not clear to me, Firefox does not open the new links after the first; It is used to open a new connection in new tabs (according to my preference) without problems in the past. Now it does not blink again.

  Over time, I've added new applications and others removed, and, of course, I can't exclude from their role in the problem that I have now. I would appreciate some help to solve this problem.

  In addition, tracks of internet explorer, but I don't like the browser...

  Hello

  > Okay, one last thing, I have glary utilities and I ran that same day before that happens.
  This utility isn't known to me so maybe the reason of this problem. You should try to remove this tool and try again. You may have to reinstall Firefox too. Check this box!

  But Firefox doesn't normally make problems. I use this browser for years now and never had a problem. I guess there's something blocking the browser. Make sure l aren AntiVirus and firewall blocking this program.

• 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:

  • Right click on a place empty on the tab bar (or the button '+')
  • Press the Alt key to activate the classic menu bar > view > toolbars
  • in customize mode > show/hide toolbars (see: Customize Firefox commands, buttons, and toolbars)

  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
  "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 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. "

  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.
  you might want to try running a scan with some various other security like the free version of malwarebytes and adwcleaner tools that are specialized to remove the adware and browser hijackers.

• 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!
