This website was mentioned in a Google help thread, and was created to prevent your chrome browser from closing multiple tabs. But yes there is a workaround created by one user just to prevent chrome from closing multiple tabs accidentally. Previously there was an extension (Chrome Tool Box By Google) which served the purpose of preventing chrome from closing from multiple tabs but that extension is no longer functions. But think of a user who accidentally closed so many tabs, how he feels Well google has some explanation on this, it explained on several help threads saying it’s just wants to have less pop-up as necessary.
For Chrome users, all the tabs will be closed automatically without any pop-up or notification asking if you’re sure that you want to close all tabs, or even just the last one.
When you are researching something on google there is a chance by ending up with multiple tabs open where you can’t even check the name on the chrome TAB, when you suddenly close the chrome accidentally it can be frustrating when you accidentally close them all at once.
