One of the most useful addons Rated 5 out of 5 stars

I love this addon. I use it everyday. I am a student and writing a research project and instantfox helps me to find every information quickly I just select a word and search for it in any of the sites like wikipedia, google, oxforddictionaries, google scholar, etc. also i use youtube, imdb, google play market. Also with shortcuts it's very easy to search. I really love instantfox and firefox (because other browser don't have such excellent addons)
