The New Chrome extension solves one of the biggest complaints about the browser – that it gobbles up memory, forcing your machine to slow to a crawl and sending the fans into overdrive.
It does that in a really simple way: Suspending tabs that you’re not using until you return to them and reactivate the process.
You can whitelist commonly used sites to make sure they never get suspended, and there’s lots of granular control (e.g. you can select how long before tabs are frozen and automatically reactivate tabs when you return to them.)
If you’ve found Chrome regularly cripples your computer, but are addicted to its features and extensibility, The Great Suspender is seriously worth considering.
