noreferrer Highlighter

Highlights all links with rel="noreferrer" attribute

noreferrer Highlighter — a tiny utility for developers, SEO specialists, and the privacy-curious. It scans every page you visit and highlights every <a> tag carrying rel="noreferrer" with a soft yellow background and a subtle outline. At a glance you can see which outbound links strip the Referer header — useful for auditing your own site, inspecting other sites, debugging SEO issues, or just satisfying your curiosity. ✨ Features • Highlights all links with rel="noreferrer" (including combined values like rel="noopener noreferrer") • Live counter shown as a badge on the toolbar icon • One-click toggle on/off — preference is remembered • "Jump to next link" button — smoothly scrolls through every match with a pulse animation • Works on dynamically loaded content (SPAs, infinite scroll) via MutationObserver • Zero tracking, zero analytics, zero network requests • Lightweight: pure vanilla JS, no frameworks, no dependencies 🔒 Privacy This extension does not collect, transmit, or store any data about you or the pages you visit. All work happens locally in your browser. 🛠 Permissions • "activeTab" — to read links on the page you're viewing • "storage" — to remember your on/off preference • host_permissions: <all_urls> — to highlight links on any site you open (the extension never sends data anywhere) Open source. Pull requests welcome.
