Latest version
Version 1.0.1
Released Jun 18, 2026 - 27.04 KBWorks with firefox 140.0 and later, android 142.0 and laterv1.0.0 — Crawler-Accurate Previews
New- Raw HTML preview for Discord and Twitter/X: These platforms crawl the server-rendered HTML without executing JavaScript. The Discord and Twitter tabs now fetch and parse the raw HTML, so you see exactly what those platforms' crawlers see — not the JS-mutated DOM.
- SVG image detection: Both Discord and Twitter/X don't render SVG embed images. The preview now hides SVG
og:image/twitter:imageand shows a warning, matching real platform behavior. - JavaScript-injection warnings: If a meta tag (e.g.
og:title,og:description) exists only after JavaScript runs, the Discord and Twitter tabs now flag it with a note — that tag is invisible to crawlers. - Version badge: The popup header now displays the addon version, synced automatically from the manifest.
Improved- Analysis tab now detects:
- Meta tags injected by JavaScript (flagged as a warning with actionable advice to render server-side).
- SVG share images across
og:imageandtwitter:image(previously only caught one). - Fallback behavior: If the raw HTML can't be fetched (CSP, network issues), Discord and Twitter tabs fall back to the rendered DOM and warn that the preview may differ.
Note
Google Search results continue to use the live DOM preview, since Googlebot renders JavaScript. This is intentional and accurate.Source code released under MIT License
