WBX3 v3.0.4
Developing
Download the source code, then unpack it. After, go to /Extension/src/block.json, and in line 9, change example.com to the domain you want to block. Finally, npm run build at /Extension/. Done! You now have a blocking extension in .zip, .xpi, and .crx format. Remember, if you're using this as production software, remember to sign the .CRX file (Go to chrome://extensions, enable Developer Mode, and use Pack Extension).
Testing
You can try out the demo of the extension attached in the assets. The extension will block example.com.
