Apture Highlights Is Awesome On-Screen Search Assistant For Firefox [Extension]

Coming across certain obscure terms/phrases is always a headache when you’re reading an article which is far too off your discipline, in such situations users tend to look up meaning of complex terms on Wikipedia and on other various websites to understand the context. Even though you can use Auto Context to initiate search in separate tabs via right-click menu, we think that you’d be better off using Apture Highlights – an elegant Firefox extension which offers on-screen assistance for understanding meaning of the selected word or phrase. It provides you selected phrase-related references in rich photos and videos format from Flickr and YouTube, updates from Twitter and elaborated articles from Wikipedia.

Apture Highlights supports hotkey registration to launch it up quickly. By default, it comes with Ctrl+Alt+L hotkey, however, you can change the combination for your ease. The best usage is to select a word/phrase and click Learn More button.
