Hands down this is my favorite bookmarks and tabs manager. Not only does it let me save all my tabs in one folder in their easy to find list type platform but allows me to create different lists for each session. It also lets me open all the tabs at once too.
This is great for storing articles to read later, great for storing multiple articles at a time, or storing tabs so that you can easily open them at once.
I'm surprised someone has not mentioned it here so far!!
