## Description

HandlerHound is a Firefox add-on for auditing inline DOM event-handler patterns.
Inline handler attributes (<code>onclick</code>, <code>onchange</code>, etc.) can accumulate in legacy or template-heavy codebases, making behavior harder to trace and maintain. HandlerHound provides a rapid scan of these patterns and highlights where handlers may be attached in risky places.
