1- Panick Button
“PanicButton makes it easier for you to hide all of your tabs at once just by clicking on a button. They are then saved as bookmarks in a separate folder. Afterwards, the PanicButton turns green and shows you how many tabs are currently hidden.”
2- Too Many Tabs
“Ever tried having 20 tabs or more open in Chrome? You can’t even see the favicon of the tabs, not to mention the tab titles! If that happens to you, TooManyTabs is a must-have extension that manages your tabs, reduces your tab overflow, and saves your sanity!”
3- Quick Tab
This is similar to Too Many Tabs in that it also saves the history of the tabs you open. This one here provides a drop down menu of all the tabs you have checked .
4- Close Tabs
This is a smart extension that allows users to perform a set of actions all having to do with closing tabs. You can , for instance, choose which tabs to close whether the ones on the left or the others on the right and many more.
5- Session Manager
Session Manager enables you to save the whole session you are working on with its multitude of opened tabs. It is like the two first extensions I mentioned above.
6- Tab Cloud
This is by all means one of the best Chrome extensions. It allows users to open their closed tabs in any other computer. All you need to do it is to sign in with your Google account. It is awesome.
7- Tab Counter
This is a great extension for those who love to keep track of how many tabs they open. It provides you with statistics about the tabs currently opened, the ones you opened for today and also the number of all tabs you opened since its installation.
8- Tab Jump
This is also an awesome extension to install on your Chrome browser. It provides three columns : Undo ( for recently closed tabs ), related ( it lists other tabs opened by the same site you are currently viewing ), and Jump ( for frequently closed tabs ) .
