I just found this awesome chrome extension called Hush for saving secret bookmarks and password protect them. Hush is a private bookmarking extension to privately save your favorite web pages or links when you’re browsing the web incognito. It’s free and easy to use!
Browse in private with incognito mode.
When you don’t want anyone to check your browsing history and see what websites you have visited, you must use your browser’s Private or Incognito mode. By browsing the web in incognito mode, pages that you view won’t appear in your browser’s history. So anyone who opens your browser can’t check the browsing history and see where you’ve been.
Even in incognito mode any files you download or bookmarks you create will be kept. So what will you do if you want to save your secret websites while browsing in incognito mode? Bookmarking just can’t cut it as it would defeat your purpose of privately browsing the web and anyone using your computer can see them. Hush is a browser extension that’s created to solve this problem. Hush is a great browser extension in Chrome for hiding your secret bookmarks that you don’t want anyone who opens your browser to accidentally come across.
The Hush private bookmarking extension doesn’t ask you for your name or email, you just need to enter a secret password to create a set of bookmarks. Each set of bookmarks in Hush is secured by a password of your choosing. You can easily make multiple sets of bookmarks by choosing a different password for each set. All your secret bookmarks are encrypted using the highest standards and they’re only stored on your computer. So any would-be snoopers will never be able to see what you’ve bookmarked.
Hush private bookmarking extension for Chrome has a number of useful features like bookmark links on a web page, bookmark all tabs with a single click, importing/exporting bookmarks, and the best part is that you can get access to your private bookmarks in any Chrome browser, on your computer, tablet or phone.
