The Great Suspender has been around for a long time; I posted it to Product Hunt ~2 years ago: <a href="https:&#x2F;&#x2F;www.producthunt.com&#x2F;tech&#x2F;the-great-suspender" rel="nofollow">https:&#x2F;&#x2F;www.producthunt.com&#x2F;tech&#x2F;the-great-suspender</a><p>it&#x27;s pretty good. I don&#x27;t really use the auto mode much, but I use it to manually kill tabs (can be faster than killing via the task manager)
