Save and organize your most-used browser tabs into lists: Toby
Toby is a free Chrome extension which allows you to save, organize into lists and sync favorite sites and links open in your browser tabs.
How it works: Simply click the Toby extension icon and you are ready to see all of your open tabs listed in a vertical sidebar. From there you can drag and drop your favorite ones into lists that remain saved and that you can re-open at any time with one click.
100% free.
My comment: Wonderful, intuitive, easy-to-use solution to manage and organize your browser tabs. Highly recommended.
