access to websites is not under the control of the operating system. You can block applications, but not websites.

You can access (and block, for that matter) only by the use of "browsers." The one you used to post this question here, yes.

Suppose it's Mozilla Firefox. You can look for extensions that can do the trick for you. I would not go fishing for them, but I used to have an extension that would "blacklist" websites so that they never open.

If you don't use the browser, the website won't open, you understand that, right? So, the trick lies in the browser. Please post a similar question to the support forums of the particular browser(s) you use to access the internet and want to block sites from.

Consider taking some time to read the official documentation regarding Parental Controls at as it discusses some of the options available to you.
