Question: Chrome always quit when I click on the `X` button on a tab, without asking me anything!
 Even when I close Chrome he do not alert me if I am willing to relay close it? 

Many times it happened that accidentally I clicked on `X` button.

Answer: 
If you accidently close all your tabs you can reload Chrome and press `CTRL` + `SHIFT` + `T`.

This will restore your previous session for all your tabs.

You could also look for a Chrome extension such as [Windows Close Protector](https://chrome.google.com/webstore/detail/lnpifgapnmpninomacbhdlconlpikdai).
You can also "restore the last session," which will include text in text boxes, if you closed the program accidentally. 

* Go to your Chrome shortcut, right click, select "send to desktop (create shortcut)"
* The new shortcut will be named Google Chrome (2), rename this to Restore Last Session
* Right click and select properties
* At the end of the target field (....\chrome.exe"), leave a space and add `--restore-last-session`
* Click Apply, then OK.

So now you have an easy way to get back all the tabs. 

Note: It won't restore incognito windows.
