Safari 12.0 - Button Compatibility

The Safari 12.0 browser is compatible with the iConsumer Button.
The Safari 12 upgrade disables the iConsumer  -- you need to enable it again. 
Be sure to enable the Button to ensure you receive credit for your shopping.
To enable the iConsumer Button, click on the Menu & select Preferences:

Choose Extensions. Click: Enable.
If this doesn't work, please follow these Troubleshooting Tips.
