I use Auto Tab Discard [0], which offloads tabs after a period of time. They still show as normal tabs (with a "ZZZ" icon to indicate it's been discarded), and the website reloads when I switch to them.

When I open the browser after closing it, the session is restored with all but the current tab offloaded so it opens quickly and using very little resources.

My current session has tens of tabs, only a handful of them active. It uses about .5% CPU when idle, and less than 1Gb RAM.
