Browser extension that allows one to share using the classic LinkedIn interface.
Since LinkedIn's recent site redesign, it became difficult to share to groups, Twitter and contacts at the same time. With this browser extension, you can share any web page using the same mechanism as the in-page share buttons, even when the page itself doesn't have the button.
The extension is available both for Chrome (https://chrome.google.com/webstore/detail/classic-share-for-linkedi/djnkioafcbjmfinanpoinhkggkngngee) and Firefox (https://addons.mozilla.org/en-US/firefox/addon/classic-share-for-linkedin/).
