Did you try to rename the file cert8.db (cert8.db.sav) in the profile folder and maybe secmode.db as well?

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;

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.

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.

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.

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.

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.

"Could not initialize the application's security component" already erased mozilla directory containing profiles and the other in x86, problem persists!

This has just happened. But I have erased the mozilla directories containing the profiles and as well the both mozilla directories in program files x86. Yet when Firefoz is reinstalled, problem recurs.
Receive again the message "Could not initialize the application security component."
Have looked at the fixes available. Those appear not to work.
Anyone else with ideas? Maybe some hidden files that I can search for on my computer, and erase?
I'm suspecting I need really a thorough erase of anything connected with Firefox, to solve this issues. Thought though I had found everything.
Not relishing the prospect of erasing the hard-disc to fix this, though that has 100% probability of working.
My computer is running Wista 64.

Rename secmod.db (secmod.db.old) in the Firefox Profile Folder in case there is a problem with the file.
Firefox will create new files.

I am using terminal services and one of my users gets could not initialize the application's Security component.

The only way I have been able to resolve this is to reboot the server. This is typically unacceptable since I have other users working on the same server.

This is an Alert when I open the browser. It isn't functioning at all. I've cleared ample space on my C drive, but I cannot find the application's profile directory to check the read/write restrictions.

The application can "not initialize the application's security component" and so Firefox will not open any more... PLEASE ADVISE!!

One day while trying to run the firefox application a box popped up and said:
"Could not initialize the application's security component. The most likely cause is problems with the 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."
Ive tried everything and even deleted and then reinstalled firefox... We miss it!!

Please try
* disabling any background anti-virus software you have, as it may be using Firefox files while it loads and prevent it from reading them
* following the steps at [[Could not initialize the browser security component]]

If deleting or otherwise removing the cert8.db and secmod.db file doesn't help then try a new profile.

Create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.
