By default, when viewing search results of people (for example: employees at a particular company), LinkedIn will show "shared connections" only after you click a link on each person that you have mutual connections with. This extension will automatically expand those links anywhere they occur.
After installing, you can test the functionality by using LinkedIn's advance search to view all of your 2nd degree connections. If the extension is working properly, you will see the names of shared connections. Here's a link to all of your 2nd degree connections: https://www.linkedin.com/vsearch/p?openAdvancedForm=true&locationType=Y&f_N=S&rsid=72658491483148356829&orig=ADVS

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!
