  • Everytime I use firefox to connect to the internet I get an alert saying that firefox could not initialize the applications security component. What does this mean and how do I fix it?

    When I use firefox to get on to the web I get the following message everytime: "Alert: Could not initialize the applications security component. The most likely cause is problems with files in your applications pforfile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security feactures." Once I click the "OK button" at the bottom of the alert box firefox starts but does not act right. For instance it will not let me look for software updates. When I click on "Check for Updates" from the "Help" drop down menu I get a message stating: "There were problems checking for, downloading, or installing this update. Firefox could not be updated because: Update XML file malformed (200). You can update firefox manually by visiting this link and downloading the latest version."

    The following support articles should help:

  • On startup I get a warning "Could not initialize the application' security component...", click OK Firefox starts but I cannot navigate to any URL but home.

    Click the Firefox 4 icon. A window opens with the warning:
    "Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features"
    (There are no read/write restrictions on my Applications folder and plenty of room on the hard drive.)
    Click OK and Firefox opens at the home page, but I cannot navigate to any other URL or link. I had the same behavior when I tried FireFox 3)

    First, use a specific [[Managing profiles|profile]] for Firefox 4.0 Beta and keep your current one for Firefox 3.6 to prevent interferences between both versions.
    Then, see [[Could not initialize the browser security component]].

  • What should I do about the alert "Could not initialize the application's security component...." Firefox no responding.

    When I open up firefox I get the alert:
    Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem.

    When I click OK I get my home page (google), but nothing works: no web sites will open. I have downloaded the new version of firefox and carried out a defraggle without success.

    This solution worked for me:

    The step that worked for me was to locate and delete the cert8.db file.

  • I'm getting Could not initialize the application's security component, when opening Firefox and I can't bookmark anymore, why?

    Here is the message I get when I open Firefox;
    Could not initialize the application's security component. The most
    likely cause is problems with files in your application's profile
    directory. Please check that this directory has no read/write
    restrictions and your hard disk is not full or close to full. It is
    recommended that you exit the application and fix the problem. If you
    continue to use this session, you might see incorrect application
    behaviour when accessing security features. Plus I can't bookmark anymore.

    Rename secmod.db (secmod.db.old) in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] in case there is a problem with the file.
    You may have to rename cert8.db (cert8.db.old) as well.<br />
    Firefox will create new files.

    When I open the application the following alert appears: "Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory." There is a solution on the support site but only for Windows-based Firefox, and I'm a Mac user. I have plenty of room on my hard disk.
    == This happened ==
    Every time Firefox opened
    == Two days ago, for no apparent reason.

    In Mac OS X v10.7, the $HOME/Library folder is a hidden folder.
    Open Finder and use one of these:
    * Go > Go To Folder (Shift-Command-G) and in the dialog type: ~/Library
    * Open the "Go" menu and hold down the Option key to make the Library appear
    You can also use this command in a Terminal window to remove the hidden flag.

  • I keep getting the following error message: "Could not initialize the application's security component." Firefox then crashes when I try to enter a secure website. Help?

    The exact error message is: "Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features." I am on a MacBook and have been using Firefox for years without any problem until now.

    Can you access other apps? Can you acess the internet? Can you access applications that use internet besides facebook?
    If answer is yes to all of these; contact Facebook.

  • Could not initialize the application's security component when clicking on a hyberlink from LotusNotes, default browser Firefox

    I have Lotus Notes 8.5 installed on Windows 7 computer.
    Firefox 4.0.1 works fine.
    But when I change FF as default browser and launch a hyperlink from My mail client I get an error "Could not initialize the application's security component. The most likely cause is problems with files in your browser's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the browser and fix the problem. If you continue to use this browser session, you might see incorrect browser behavior when accessing security features."
    After this error I can open tabs but no website will work.
    But if I close Firefox and reopen it will work.
    When Firefox is running, if I click the hyberlink from my mail client, it launches without error message and works fine.
    Gave Write access to profile folder. replaced cert8.db etc, but it is not helpful.
    I installed Firefox 4 - same.
    Installed Firefox 5 beta - same.
    Installed Firefox 3.6.17 - error message is there but Firefox keeps working after launch.

    You do have one or more empty photo frames. Most often it will be a full page photo page missing behind a placed full page photo. To find it you need to go through you'd book and look behind each full page photo

  • Firefox Error with Roaming Profiles "Could not initialize the application's security component"

    Hi there
    I get the common error "Could not initialize the application's security component" when I startup Firefox.
    I tried this manual: http://support.mozilla.org/en-US/kb/couldnt-initialize-applications-security-component
    I have enough space left, i have read/edit/write-rights, created a new firefox profile and also reset all the settings, nothing works.
    BUT I dont have a cert8.db File in my %APPDATA%\Mozilla\Firefox\Profiles
    What can I do?
    Like I said in my description, its about Users that are logged in with a Roaming-Profile. Every User has this problems, it doesn't matter if or without Admin-Rights.
    Also this problem exists since Firefox 4.0.0, the last working Version was 3.6.13 I guess.

    You can use this button to go to the Firefox profile folder:
    *Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
    Try to remove or rename secmod.db (secmod.db.old) in the Firefox profile folder.
    If that didn't help then also rename the cert8.db file to cert8.db.old or delete the cert8.db file to remove intermediate certificates that Firefox has stored.
    If that helped to solve the problem then you can remove the renamed cert8.db.old file.<br />
    Otherwise you can rename (or copy) the cert8.db.old file to cert8.db to restore the previous intermediate certificates.<br />
    Firefox will automatically store intermediate certificates when you visit websites that send such a certificate.
    Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
    Download a fresh Firefox copy and save the file to the desktop.
    *Firefox 25: http://www.mozilla.org/en-US/firefox/all.html
    Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
    *Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you lose personal data like bookmarks and passwords from profiles of other Firefox versions.
    Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
    *(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
    *(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
    *It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
    *http://kb.mozillazine.org/Uninstalling_Firefox
    Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
    If you keep having problems then also create a new profile.

  • Firefox stopped working properly, it says it cannot initialize the applications security component...

    Firefox starts with this: Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features.
    it then opens and will not let me click anything, just opens the homepage and stops, tried reinstalling and it still doesn't work.

    Create a new profile as a test to check if your current profile is causing the problems.
    See Basic Troubleshooting: Make a new profile:
    *https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
    There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
    If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)
