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.
