Compatibility of Kaspersky Safe Kids with the Mozilla Firefox browser
In the Mozilla Firefox browser, Kaspersky Safe Kids does not block HTTPS websites that contain content that is inappropriate for children if the Primary Password feature is enabled in the browser settings. When opening such a website, you will see a warning about the untrusted Kaspersky Safe Kids certificate. Due to this limitation, Mozilla Firefox is blocked by default in child accounts.
Update Kaspersky Safe Kids to version 188.8.131.520 or later.
In version 184.108.40.2060 and later, Kaspersky Safe Kids makes changes to the Mozilla Firefox settings every time you run the browser. These changes let Firefox use certificates from the local computer store instead of the Firefox certificate store.
You can download the latest version of Kaspersky Safe Kids from the Kaspersky website.
