It does convert the problem from a giant mess of tabs to a giant mess of bookmarks, but at least bookmarks don't use much CPU/RAM.
I was thinking of installing The Great Suspender, but not all my tabs are ephemeral, but I guess it has a way to configure domains it shouldn't suspend, so I might try that together with your extension.
