Former add-on called Last Tab Close prevented the window from closing when you closed the last tab. How to get that functionality in FF 57?

With 57, if I close the last tab connected to a website the whole window closes. Formerly, closing the last [web] tab prompted/showed the "new tab" where I have my pinned pages. This was very helpful. Is there a way to get 57 to do that?

Go to about:config in Firefox's address bar and confirm the warning to continue. Search for browser.tabs.closeWindowWithLastTab and set it to false.
