If you in habit of opening a number of tabs then after some time you get messed up with many open web pages and at last you have to copy-paste URLs in may be your notepad or something, this temporarily solves the problem but increases unnecessary steps next time you try to open those links in your browser.
If you are a Google Chrome user then you can make this thing very handy. First of all install Tab Packager extension in your chrome browser. It allows you to create a link connecting a list of all the tabs open in your current Chrome window. Now it comes with a brand new domain (tab.bz), the ability to pick and choose tabs and super quick sharing buttons!
