Could not initialize the browser's security component Error message when sending a link

Using Ubuntu 9.10 64 bit. Firefox version is 3.6.3 and Thunderbird version is 2.0.0.24
When sending a link with Firefox I get an error message "Could not initialize the browser's security component...". Tried deleting the cert8.db and secmod.db. Noticed if Thunderbird is already open I don't get the error message. But if Thunderbird is closed then opens to send the link I get that error message. Seems the security certificates aren't being passed to Thunderbird when it is opening up.
== This happened ==
Not sure how often
== 2 days ago.

Try to remove or rename the secmod.db (secmod.db.old) file in the Firefox Profile Folder.
If that didn't help then remove or rename cert8.db (cert8.db.old) as well.
You can use this button to go to the Firefox profile folder:

  • We are still having problems with the "Could not initialize the application's security component" error message after performing suggested fixes?

    We have been attempting to resolve this error in our Lab Environment with FireFox version 14.0.1. The application has been virtually installed in our PC environment, running WIN 7 and launches without error for most users. When performing the suggest "fixes" at http://support.mozilla.org/en-US/kb/couldnt-initialize-applications-security-component we found:
    1. There is adequate hard drive space
    2. Permissions are set correctly.
    3. Once the "Cert8" file is deleted it does not regenerate upon logging out and relaunching Firefox. Not sure why this occurs.
    4. Could not create a new profile since these rights are not extended to users in the lab environment.
    Is anyone using Firefox in a similar lab environment, having this same issue and been able to resolve the problem? Does version 15.0.1 address this problem and provide a fix?

  • 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.

    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 uninstalled the browser and download a new version but it does not resolve the issue.
    I know my hard disc has ample space. I do NOT know where to find the Profile directory to fix the read restriction box.

  • New WIN7 System, FFox gives error "Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory" - will not go to any site.

    New Windows 7 computer. After installing Firefox, every time I bring it up I get the following message:
    "Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory.

  • 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.

    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.

    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.<br />
    You may have to rename cert8.db (cert8.db.old) as well.<br />
    Firefox will create new files. If that works then you can remove the renamed files.

  • 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.

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.
