I've been looking for a pop-up word definer ever since seeing an example on MS Edge. It's great no longer having to use "Search in Google" to find a word def and messily opening a new tab.i gave it only 4 stars bc there's always room for improvement in everything. One change I would make is not having to use 2 mouse clicks to get a def (right click on a highlighted word then left click on the "Define" entry): I would make it so clicking the add-on icon in the toolbar when a word is highlighted opens the pop-up window with the word defined. It already opens the pop-up so I don't see the issue. Thanks and Cheers, r
