Too many open tabs? Extensions to the rescue!

The first step in getting help with your tab hoarding problem is to admit you have a tab hoarding problem. Whatever the reason may be—your job requires you to have dozens of open tabs or the rows of tabs represent your neverending “read later” list—you can regain control of this spiraling situation with the right browser extension. 

Tree Style Tab

Organize your tabs into a clean, cascading “tree” format. Tree Style Tab opens new tabs as “branches” of the parent tab, so all of your open tabs are automatically organized in an easy-to-glance tree branch layout.
