Family Site Guard

Blocks the sites on your block list. Permits their embedded frames only on the sites that you approve.

Family Site Guard blocks the sites on your block list, and it keeps their embedded content alive on the sites that you approve. Example: block YouTube, and the YouTube videos inside your school site continue to play. The child can watch the lesson, but can not open youtube.com itself. Most blockers stop at the first half. The second half — embeds that continue to work on the sites that you choose — is the reason this extension exists. How it works - Direct navigation to a blocked site stops. Chrome shows its standard message: this page was blocked by an extension. - Embedded players and media from the blocked sites do not load on other sites. - A link inside a permitted player that opens the blocked site in the tab or in a new tab stays blocked. - The toolbar icon shows the two lists, so everybody can see which sites stay available. - The extension does not read your browsing history, and it does not read the pages that you open. It gives Chrome a fixed set of rules, and Chrome applies them. It can remove the stored copies of the blocked sites, so that the block works; it touches nothing else. For families - Two simple lists: blocked sites, and sites that may embed content from them. - A block entry is a domain (youtube.com) or a keyword (youtube). A keyword blocks every site whose address contains it: youtube.com, m.youtube.com, youtubekids.com, and proxy addresses that keep the name. - An administrator policy can hold the lists. Then a child can not change them, can not remove the extension, and can not escape it with a new Chrome profile. - The extension makes the policy file for you, for macOS and for Windows. You choose the sites. Both lists are empty at the start, and the extension blocks nothing until you fill them. An approved site can show every type of frame from a blocked site, so approve only sites that you trust. Get started 1. Install the extension. 2. Right-click the toolbar icon and select "Options", or open chrome://extensions and click "Details" then "Extension options". 3. Write the two lists, one entry on each line, and click Save. A block entry is a domain such as youtube.com, or a keyword such as youtube that blocks every site whose address contains it. The rules apply immediately. This simple setup is good for your own computer. Each user of the profile can open the same page and change the lists. For absolute control on a family computer 1. Open the options page and fill the two lists. 2. In the "Export a policy file" section, enter this extension's ID and download the file for macOS or Windows. 3. Install that file on the family computer with an administrator account. The file carries an ExtensionInstallForcelist policy, so Chrome installs the extension on every profile of that computer, with the lists locked. Nobody can change the lists, remove the extension, or escape it with a new profile, a guest window, or an Incognito window. The extension collects no data and sends no data. All rules operate in your browser. What's new in 0.1.1 - A block entry can now be a keyword. The keyword youtube blocks youtube.com, m.youtube.com, and youtubekids.com together. - A blocked site could still open if the browser kept a copy of it from an earlier visit. The extension now removes those copies, so the block works everywhere. The settings page has a button that removes them at any time. - Videos on an approved site now play in more places, for example inside the widgets of a learning platform. - Sound and video elements are blocked like frames. - The settings page says clearly when the browser does not accept the lists. - The policy files also stop web addresses that start with javascript:, and bookmarklets.
