// Single-Click Version:
// 1. Create a bookmark with:
javascript:document.body.addEventListener("click",function(t){for(var e=window.getSelection(),n=e.getRangeAt(0),o=e.anchorNode;0!=n.toString().indexOf(" ");)n.setStart(o,n.startOffset-1);n.setStart(o,n.startOffset+1);do{n.setEnd(o,n.endOffset+1)}while(-1==n.toString().indexOf(" ")&&""!=n.toString().trim()&&n.endOffset<o.length);n.toString().trim();e.focusNode.nodeValue=e.focusNode.nodeValue.replace(n.toString().trim(),"***")});
// 2. Place your bookmark on your bookmarks bar
// 3. Push the button when you want to censor your name / anything else
// 4. Click on the word you want to hide

// Double-Click Version:
javascript:document.body.addEventListener("dblclick",function(t){for(var e=window.getSelection(),n=e.getRangeAt(0),o=e.anchorNode;0!=n.toString().indexOf(" ");)n.setStart(o,n.startOffset-1);n.setStart(o,n.startOffset+1);do{n.setEnd(o,n.endOffset+1)}while(-1==n.toString().indexOf(" ")&&""!=n.toString().trim()&&n.endOffset<o.length);n.toString().trim();e.focusNode.nodeValue=e.focusNode.nodeValue.replace(n.toString().trim(),"***")});

// Non-minified version (so you can be sure it's not malicious):
// You can minify it for youself if you want ;)
// Or change the mask... or basically anything as you want.
