DevTools Full-Spectrum Asst von Archpanda

Inspect, diagnose, and repair issues in your web apps directly from Firefox DevTools.

DevTools Full-Spectrum Assistant adds a Fix Assistant panel to help you find form problems, accessibility issues, runtime errors, and failed network requests.

Features:
• Scan the current page and review diagnostic findings.
• Get AI-assisted explanations and suggested source-code changes.
• Apply supported DOM repairs, with review controls for changes that need your attention.
• Compare before-and-after results to verify fixes and identify regressions.
• Export diagnostic reports and suggested source patches.

To get started, open a webpage, press F12, and select the Fix Assistant tab.

Opening the panel starts an audit and can send page content and diagnostic evidence to the hosted AI service. Entered form values are removed from the diagnostic snapshot, but other page content may contain sensitive information. See the privacy policy for details.

Applied DOM changes are temporary and disappear when the page reloads. Exported source patches can be reviewed and applied to your project for permanent fixes.

A free audit allowance is available, with optional paid plans for additional usage. Requires desktop Firefox 142 or newer.
