# Waterfox ## Command Mode - Take a screenshot of the entire page `screenshot --fullpage` - Take a screenshot of the visible window only `screenshot` - Restart the browser `restart` ## Preferences Waterfox has 2 preference files: `prefs.js` and `user.js`. `prefs.js` are the settings defined by the browser and `user.js` is an optional file that you can create. `user.js` takes precedence over `prefs.js` and will replace the settings in `prefs.js` when Waterfox is started. ## Theme Waterfox allows you to customize the appearance of the browser by creating your own `userChrome.css`. It is located inside of the `chrome` folder, which needs to be created by the user.
