Load the extension in Chrome & Opera
  1. Open Chrome/Opera browser and navigate to chrome://extensions
  2. Select "Developer Mode" and then click "Load unpacked extension..."
  3. From the file browser, choose to galaxy-tourbuilder/build/chrome or (galaxy-tourbuilder/build/opera)
Load the extension in Firefox
  1. Open Firefox browser and navigate to about:debugging
  2. Click "Load Temporary Add-on" and from the file browser, choose galaxy-tourbuilder/build/firefox


The following tasks can be used when you want to start developing the extension and want to enable live reload:

  • npm run chrome-watch
  • npm run opera-watch
  • npm run firefox-watch


Run npm run dist to create a zipped, production-ready extension for each browser. You can then upload that to the different app stores.
