Private Bookmarks is a free Chrome add-on created by João Magalhães that allows users to save bookmarks in a private and secure way. This add-on adds a button to your browser toolbar, which opens a password-protected interface. Once logged in, users can add websites to their private bookmarks by right-clicking a page or clicking "Add to private bookmarks" in the extension.

Private Bookmarks also offers some new features in version 1.4, including bulk delete, backup/restore bookmarks and settings, a shortcut key to add to private bookmarks, and the ability to reset the extension. In addition, version 1.3 fixed a bug when adding bookmarks from the popup menu, and version 1.2 added new languages (Portuguese, Spanish, and French) and fixed some bugs.

Overall, Private Bookmarks is a great tool for anyone looking to keep their bookmarks safe and secure. With its password protection and private interface, users can rest assured that their bookmarks are safe from prying eyes. Future updates will likely include more languages, so if you're interested in helping to translate Private Bookmarks to your native language, be sure to contact the developer.
