Why can't I access a
certain site or service when F-Secure FREEDOME is turned on?
Most likely the site or service that you are trying to access is either malicious or is trying to track you. Some sites prevent their use altogether if they are not able to set up the tracking first.
If you cannot access a site or service that works when FREEDOME is turned off, you can try to turn Tracking Protection off when you are accessing that site. Note, however, that at the same time you allow that site and its affiliates to track your online behavior.
You may also try to turn Browsing Protection off if you trust that the site in question is safe. Note, however, that this considerably weakens the security of your web browsing.
