At start up, messase "could not initialise application's security component

My Grandson has a Toshiba laptop. When he attempts to start Firefox this message appears:
"Could not initialise 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 & your hard disk is not full, or close to full. It is recommended that you exit the application andfix the problem. If youcontinue to use this session you might see incorrect application behaviour accessing security features."
Firefox does start, but just shows a blank page.
Can you advise what he should to eliminate the problem?
Thank you
Frank Howe

When starting firefox i get a security alert saying could not initialise application security component

this problem started yesterday. it now happens every time i start firefox. if i close the security warning window fire fox seems to run ok.

See:
*https://support.mozilla.com/kb/Could+not+initialize+the+browser+security+component

Why do I get an alert saying "Could not initialise the application's security component. The most probable cause is problems with files in your browser's profile directory. How can I solve it??

The full alert is " Could not initialise the application's security component. The most probable cause is problems with files in your browser's profile directory. Please check that this directory has no read/write restrictions and your hard drive 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 behaviour when accessing security features."
This is just started three/four days ago. I need assistance quickly as I can't access any secure sites e.g bank accounts/homepage etc.

See [[Could not initialize the browser security component]]

An alert message pops up upon opening saying could not initiate application security component, and it says to check to see if profile has no read/write restrictions.

An alert message pops up upon opening saying could not initiate application security component, and it says to check to see if profile has no read/write restrictions. Than when it opens all of my saved passwords are gone, I use a master password and its disabled. When I try to enter in a new on e it says can't change password. I can't even open yahoo e-mail says that my ssl security is down but when I check it its clicked. I'm just very confused as to whats going on.

Rename (or delete) 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.

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. If you continue to use this session, you might see incorrect application behaviour when accessing security features.
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

Hello,
I installed Firefox 3, I did check for update, but 4.0.1 when running show me this message:
"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 have Uninstalling 3 times Firefox but I see the same error and now I can't install Firefox, this is the question... My harddisk is ok, also and my permissions, there is not any directory of Firefox...
I have removed any directory of Firefox(also personal data)
I have Windows XP Professional... I run the Google Chrome 11.0.696.68,
After one week, I haven't any answer...
I would like to write me first: How do I fully uninstall and then: how to install Firefox;
I wait for your answer...
thanks a lot...

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.

"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.

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]]

Could not initialise the application's security component

When opening Firefox, I get a message "Could not initialise the application's security component. The most probable cause is problems with files in your browser's profile directory. Please check that this directory has no read/write restrictions and your hard drive 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 behaviour when accessing security features." Firefox then opens but all tabs are marked New Tab and no access can be obtained to the various websites. If I try to sign in to Google, a new window opens marked About:blank. I have wireless connection which is functioning correctly. Please help get my connection working if possible.

Thank you for this detailed explanation - I suspected the answer would be somewhere although I certainly had trouble locating it.
I haven't utilised this answer as I resurrected another laptop and copied folders from the AppData Local and Roaming folders and pasted them into my corrupted machine, which is now working well. However, I am extremely grateful to you for coming to my aid and have bookmarked the reply should it fail again.
I see someone else has the same problem, so your help will doubtless reach even further. Regards

Delete the cert8.db file in the Thunderbird profile folder.<br />
This will remove all intermediate certificates that Thunderbird has stored.
