The Great Suspender is a lightweight extension to reduce chrome's memory footprint. Perfect if you have a lot of tabs open at the same time. Tabs that have not been viewed after a configurable length of time will be automagically suspended in the background, freeing up the memory and CPU being consumed by that tab.

➤ Configurable behaviour when browsing offline or on battery power
➤ Built from open source code for full transparency
