Grzegorz's Site Blocker Extension

This extension allows you to block websites specified via regular expressions.

For example, to block YouTube:

1. Open options by clicking on the extension’s icon.
2. Click the add button.
3. Write `youtube.com` in the newly added text field.
4. Enable the rule by marking the checkbox on the left of your rule.

The extension will now block every URL that has `youtube.com` and redirect the window to a Wikipedia page on Akrasia.

The extension is basic and I built it to be extremely simple so that I could allowlist it on my employer’s machines to block distracting internal sites. I couldn’t use other external extensions (e.g., Freedom, BlockSite) for that purpose.

Graham Poulter (ID: 0000009cd4e088f7) Voted 4 ★ - Updated 08/22/2021 This extension does what it says on the tin. Runs entirely in-browser (no HTTP requests), and is only about ~100 lines of code, find on GitHub under gregorias/grzegorzssiteblocker. The UI is a little rough, just beware that the box needs to be checked for the site to be blocked, and if any URL patterns are invalid then no sites will be blocked.
