Although secure https-based websites can be blocked, a browser extension is needed to display the Block Page properly. We offer a free browser extension that optimizes the end-user experience as follows:
For Chrome, one of two block page extensions can be used:
Allows for HTTPS block page support and shows domain dependency listing. Available at the Chrome Web Store, OR
Block Page Assistant
This unbranded extensions only provides HTTPS block page support. Available at the Chrome Web Store.
Here is a before-and-after example:
Firefox is not currently supported.
Edge is not currently supported.
Safari no longer offers the functionality needed for the block page assistant to work. If this changes, we plan to reimplement our extension.
