Cross-Browser Extensions Sync

Sync your installed browser extensions and state across Chromium browsers and Firefox via GitHub Gist.

Cross-Browser Extensions Sync is a lightweight, privacy-focused extension that synchronizes your installed browser extensions and their enabled/disabled states using your own private GitHub Gist. No third-party cloud accounts, no analytics, no external servers — your data stays under your control. KEY FEATURES: 🔄 Cross-Browser Extension Matching Automatically bridges 32-character Chrome/Edge Web Store IDs with Firefox Add-on GUIDs and slugs, allowing seamless cross-browser state synchronization. ⚡ State & Ignore Synchronization - Enable/Disable State: Toggles installed extensions on/off to reflect your synchronized configuration across devices. - Sync Modes: Choose between Smart Merge (bidirectional merge based on timestamps), Push (upload local state), or Pull (download remote state). - Synced Ignore List: Mark extensions to ignore so they remain local without cluttering your synced setup. 📦 Quick Installation & Store Shortcuts - Direct store links for missing extensions across Chrome Web Store, Microsoft Edge Add-ons, and Mozilla AMO. - One-click batch actions to quickly review and install missing extensions on a newly configured browser. 📊 Full Dashboard & Popup - Filter extensions by All, Installed, Out of sync, Missing, or Ignored. - Search by extension name, ID, or keyword. - Backup & restore: Export and import your settings and extension snapshots as JSON. HOW TO GET STARTED: 1. Generate a GitHub Personal Access Token with the "gist" scope. 2. In the extension settings, paste your token and click "Create New Private Gist" (or connect an existing one). 3. Install this extension on your other browsers, connect the same Gist, and click "Sync Now"! PRIVACY & SECURITY: This extension communicates directly and exclusively with GitHub's official APIs to manage your Gist and with official browser extension store endpoints to resolve store links. No private data or browsing history is ever collected, tracked, or sent to any intermediary server.
