Would like to see a more simplistic icon, perhaps a flat color with a simple down arrow, that scales. The current icon looks squished.

(This was fixed, thanks!) Clicking on the "Open Server" button results in a "File not found" page:

"Firefox can’t find the file at moz-extension://ac581828-6b0b-496a-95d1-a5e69eac25ce/192.168.0.10:6789"

I'm using Firefox 57.0
