Dux-Soup disappears from my browser, how can I get it back?

The reason why your Dux-Soup icon is not showing in your browser is that it was disabled.

You can re-enable the Dux-Soup extension as follows: 

1) Open a new tab in Chrome and point it to chrome://extensions

2) Scroll to Dux-Soup and turn it on by clicking on the slider

This should let you use Dux-Soup.
