## Description

EventSentinel is a Firefox extension for auditing inline JavaScript event wiring patterns in live pages.
It scans DOM attributes such as <code>onclick</code>, <code>onchange</code>, and related inline handlers, then combines that with detection of <code>javascript:</code> anchor URLs.
