Integration of Furbooru with Imagus extension

Imagus is a web browser extension that enables opening full resolution images or videos by hovering above thumbnail or a link without opening the image itself in a new tab. Usefull for sites like reddit, imgur, twitter, e621, FA or Derpibooru:

but not for Furbooru. What would I have to paste into all those fields for it to work here? Also it would be a good idea to contact authors of that extensions so that they would include Furbooru by default, like with Derpibooru.
 
Here is the subreddit about it: https://www.reddit.com/r/imagus/

Furbooru’s not officially open yet, so they probably don’t know about it.
 
If I had to guess, create a new rule.
 
First line:  

 
Second line:  

 
Third line:

No idea if that’ll work or not though. But that should be t least a good jumping point.
