This article concerns:

  • Kaspersky Anti-Virus
  • Kaspersky Internet Security

  • Kaspersky Small Office Security
  • Kaspersky Free

When opening the Mozilla Firefox browser or Thunderbird, if you receive a notification that secure traffic for your profile in your browser is not being controlled, this means that the SSL certificate for Kaspersky Lab was not installed in browser storage.  

This could be caused by:

  • A master password. A master password is used to securely store your passwords for various websites and protect access to your certificates. 
  • More than one account existing in the browser.
  • Disabled short URL format 8dot3name.
  • Certificate installation error.
