Technical notes
Each widget is a standalone page served from unblockmaster.com and loaded in an iframe, so it cannot read or change anything on your page. It ships its own small stylesheet and no third-party scripts or trackers.
If you leave "auto-fit height" enabled, the snippet also loads a ~1 KB script that listens for a postMessage from the widget and resizes the iframe to match its content. Without it, the iframe keeps the fixed height in the snippet — which is fine, the heights we suggest fit every result state.
The widgets are available in every language this site supports. Pick a language above and the snippet points at that version.
