After this, firfox opens but whenever I go to any web page having secure connection like orkut, facebook etc. firefox crashes. It works normally through admin login.

Whenever I open firefox through non admin login, I get following alert 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."
