“Course Hero saved me when I was exhausted, behind on my school work, and simply wanting to recover from having a life outside of school.” —Jill Heller, Tulane University
“One of the most useful resources available on Course Hero is 24/7 access to tutors. Even if I don’t feel like waiting for an almost-instant response, they have a substantial database of questions that have already been addressed.” —Arunava Chatterjee, University of Oregon
“Course Hero is the best online educational resource I’ve ever used. On top of that, they make it so easy to help donate books to children in Africa through the Knowledge Drive. You can study and help a great cause at the same time!” —Aska Anwar, Georgia State University
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
