no ICON for dictionary ?? Rated 4 out of 5 stars

why has NOIA 4 no Icon for dictionary in the Add-On window ????

This review is for a previous version of the add-on (1.8.0). 

To be honest, I never installed a dictionary for Firefox, neither on my 'default' profile nor on my theme testing profiles before you asked me.
But you are lucky, the icon made it into the latest "pre" before uploading.

Noia 4 v1.8.1pre1
