You might be browsing lots of websites daily and the most common way to open them is to use tabs in the browsers. But there might be certain websites which you use commonly like emails, Facebook etc. Now you can open multiple sites in a single browser window and save tabs space. SitePouch is a nice free online service which allows you to open multiple websites in a single window and quickly navigate through them easily.
You can enter multiple sites here and create a Site Pouch. It is nothing but a unique URL to open all these websites in single window. Below is a video of the service in action, you can see three sites loading in a single browser tab. You can share the site pouch such that they can be used on other browsers or even other computers.
SitePouch is a nice service to browse to multiple sites quickly and easily, but having said that there are few sites which does not load in iFrame method and hence these cannot be used with SitePouch.
