Chrome2Fox от Neguiolidas

Chrome2Fox allows Firefox users to download and install Chrome Web Store extensions directly.

How it works:
1. Browse any extension on the Chrome Web Store
2. Click the "Add to Firefox" button injected by Chrome2Fox
3. The extension downloads the CRX file, converts the manifest, and injects compatibility polyfills
4. A ZIP file is downloaded — load it via about:debugging to test

Features:
• One-click download and conversion
• Automatic manifest V2/V3 conversion
• Chrome API polyfills for better compatibility
• Progress tracking with toast notifications
• Conversion history

Important: Not all Chrome extensions will work perfectly on Firefox due to fundamental API differences. Chrome2Fox handles the conversion, but some Chrome-specific features (like chrome.debugger or chrome.tabGroups) have no Firefox equivalent.

Always test converted extensions via about:debugging before relying on them.
