displays a simple LCD Clock in your Toolbar, mouseover on the Clock shows the Date.
Note: at the moment it is not possible to write this Addon in webextensions for Firefox 57+ because the new API does not support to show this Clock in the Toolbar, I hope that it will be possible later on.
when you need a Clock you must use a Icon in the Toolbar that open a Popup, as well as this Addon
