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. After that the PanicButton turns green and shows you how many tabs are currently hidden.

Another click on the PanicButton restores all of the tabs you have hidden earlier.

If you dont want to restore your tabs just delete the "temporary Panic" folder in Chromes "Other bookmarks"-folder.
