LinkLocker - Private Bookmarking od Jarrod Whaley

LinkLocker is a lightweight bookmarking service with an emphasis on privacy. Save your links on our secure servers, and they will be visible only to you. The LinkLocker Add-On is the best way to clip content into your account. Just click the icon when reading a page you want to save, and a clipper interface will open in a new tab. Here you can optionally add a description of the link and a number of tags before submitting the link.
