Not24Get von Andrei Petrov

Save and organize the web's good stuff straight from your browser. Sign in once, and the extension's popup gives you three simple tabs:
Save — Save the page you're on with one click. Add a note and tags, drop it in the right folder, and you're done. If you've saved a page before, you'll see it right away and can tweak or remove it.
Hub — Look through everything you've saved, search it, sort it into folders, and edit or delete items — all without leaving your browser.
Sync — Bring your existing browser bookmarks into not24get.me, or send your saved links back out to a bookmarks folder in your browser.
Your stuff stays private: nothing is sent until you sign in and choose to save, and the extension only touches your bookmarks when you ask it to import or export.
