OneTab, a free Chrome add-in, converts a set of browser tabs into a page of links, then restores the tabs when required. It can instantly free up gigabytes of memory when you need it for something else.
As a chronic die hard multiple tabs opener, Onetab litteraly made my browser usage livable.
It saved me several times, having hundreds and hundreds of tabs open and can't be simply closed.
I use it daily.
