Nook — Save to shelf by Keerat Singh Khurana

Nook is your personal shelf for the web. This add-on saves the page you're on straight to your Nook account in one click, from the toolbar popup or the right-click menu.

Add a category and tags as you save, so everything stays organized and easy to find later. Your saves sync to nookdb.com, where you can search, filter, and revisit them from any device.

Requires a free Nook account.
