Google has a staggering number of mini programs called Extensions. Extensions are available in / for the Google Chrome browser. They modify and enhance the functionality of Google Chrome.
To install a Google Extension, visit the Google Web Store.
Over the course of the next few weeks, I will be highlighting a series of Extensions that I use on an almost daily basis. I will be discussing one Extension per week, between now and the end of the school year. I hope you find them as useful as I have.
Extensity is an Extension organizer and a Google Apps viewer. Extensity's primary function is to allow you to turn Extensions on and off. Some Extensions can drain your battery or slow down your connection because it is consistently running in the background. With Extensity, you can turn these draining Extensions on and off. This gives you the ability to only have them on when you are using them. Extensity, as a Google Chrome Extension, is invaluable.
