With the website blocker, you can prevent access to any domain you want, you have the option to only enable or disable the blocking or add or remove it from the blocked list. There are 4 blocking options:
Display of a page informing you that the site is blocked
Display of a page asking for the password for unlocking (the password will not be asked again within the same tab, if a new tab is opened and trying to access the same domain, the password will be requested)
Display of a notification saying that the site has been blocked (The tab that the site was entered will be closed before displaying the notification)
Redirection to a website of your choice whenever the blocked website is accessed
