Extension Metadata

About this extension
DOM XSS Highlighter — Pro helps developers and security testers detect reflected DOM values that may indicate potential XSS risks. The extension scans query parameters and hash fragments, highlights where they appear in the page, and provides quick insights on their context. This makes it easier to spot unsafe reflections, event handler injections, and unescaped text. Designed for security researchers, penetration testers, and web developers who want to strengthen application security during testing.
