LinkGlimpse – Social Preview Checker by ctw

Audit the page open in your active Firefox tab before sharing it. LinkGlimpse displays Facebook, LinkedIn and X previews, a Google search result preview, Open Graph and Twitter Card checks, and actionable fixes—all inside the extension popup.

Features:

• Facebook, LinkedIn and X social card previews
• Google search result preview
• Open Graph and Twitter Card metadata inspection
• Metadata health score
• Title, description and canonical URL checks
• Share-image dimensions and accessibility
• Redirect, HTTP and indexing diagnostics
• Actionable recommendations for detected issues
• Fix instructions you can copy for an AI coding agent

There is no URL to copy or Inspect button. Open the extension from the Firefox toolbar and it automatically checks the current public page.

The extension runs only when you open it. It sends the active public page URL to the LinkGlimpse API solely to generate the requested report. It does not access browser history, cookies, credentials or private page content, and it contains no advertising or extension analytics.
