Firefox Addon: Html Validator
Note: This tutorial is based on Html Validator version 0.8.5.2. The details outlined below may not work in future versions.
When I make web sites, I use quite a few different Firefox extensions.
One of the extensions that I use is called Html Validator https://addons.mozilla.org/en-US/firefox/addon/249
This extension is great.
It main use is to validator the html code when you "view source" in Firefox.
It also has secondary benefit is syntax highlighting.

The Problem
However there is one problem that makes my job harder.
Error: oTidyBrowser is not defined
Source File: chrome://tidy/content/tidyBrowser.js
Line: 220
This shows up countless times in Firefox’s error console, making the job of finding other errors really hard.
