Tabs are really useful while browsing multiple sites in a single window. Most of the times when we open a link in a new tab, we don’t know which one is the parent tab. If you ask me what is the need to find the parent tab then let me tell you that the parent tab helps to understand the relation between its child tabs.

Tree Style Tab provides tree-style tab bar, like a folder tree of Windows Explorer. New tabs opened from links are automatically attached to the parent tab. If you often use many many tabs, it will help your web browsing because you can understand relations of tabs.
