Advanced search tool Rated 4 out of 5 stars

This extension lets the user search for HTML elements which contain a search string. The user can also increase the range of shown elements by increasing the tolerance which represents the number of parent nodes shown. It doesn't manage content loaded by Javascript yet. One error in console, but haven't seen a problem:
Error: document.getElementById("botonmas") has no properties
Source File: chrome://slicetoolbar/content/slicetoolbar.js
