Troubleshooting

Make sure you selected the correct folder — it should contain a manifest.json file at the root level. If you see nested folders, navigate into them until you find manifest.json.
Click Errors on the extension card in chrome://extensions to see what went wrong. Common issues:
  • Manifest parsing error: You may have downloaded the wrong file. Re-download from our Discord.
  • Permission errors: Make sure you’re using a supported Chrome version (100+).
The extension only activates on supported sites (RapidLaunch, Uxento, J7 Tracker, Axiom). Navigate to one of these platforms to see it activate.
The installation process is identical. Navigate to your browser’s extension page:
  • Brave: brave://extensions
  • Edge: edge://extensions
  • Arc: Settings > Extensions
