New Tab Widget is a Chrome extension that adds a toolbar icon that allows you to add any page as a "bookmark" (not a browser bookmark). It adds a New Page tab that lists all of the sites that you have visited and the pages that you have bookmarked so that you can quickly navigate to them.

Once you have installed the extension, simply add the page you want to bookmark by clicking the New Tab Widget icon. This is the icon that will appear in your New Tab, allowing you to add bookmarks or edit existing ones.

Once you have created the bookmark, you can modify its title and URL.
