```

By default, the extension connects to `http://localhost:3100/api`.

## Development

The extension uses Manifest V3 and consists of:

- `manifest.json` - Extension configuration
- `popup/` - Popup UI (HTML, CSS, JS)
- `background/` - Service worker for context menus
- `content/` - Content script for page extraction
- `icons/` - Extension icons

## Icon Generation

To generate PNG icons from the SVG:

```bash
# Using ImageMagick
convert icons/icon.svg -resize 16x16 icons/icon-16.png
convert icons/icon.svg -resize 48x48 icons/icon-48.png
convert icons/icon.svg -resize 128x128 icons/icon-128.png
```

Or use an online SVG to PNG converter.
