Bug: Cannot Activate Safari Extension On iOS

This fixes the bug that all safari extensions are greyed out in the settings.

Problem

If you go to Apps > Safari > Extensions and want to enable a new extension like OneSec, it is not possible because everything is greyed out.

Solution

Content & Privacy Restrictions are turned on in the Screen Time settings. Turn them off, then the extensions can be enabled. Afterwards, you can turn them on again, the extension keeps activated.
