BleepingComputer.com: Security problems with firefox

I just downloaded mozilla firefox and this message appears when I sign in..

(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 did a search for profile directories with no result and I have plenty of space on my hard disk

can someone help me

If you had just installed it, I assume you don't have many customizations and such. Perhaps a repair/reinstall should work?

Also, you can create another profile using the profile manager. Make sure Firefox is not already running. If you are on Windows, goto Start>Run>Type "Firefox.exe -P". From there create a new profile, name it anything. See if the problem still persists.
