lowers firefox memory use

Poderia ter uma interface mais amigável, mas fora a isso funciona bem

Love how it puts a sleep sign on inactive tabs, but when opening a sleeping tab I don't have to click again on the page to open it, the page opens automatically. Well done!

Essential addon

Excelente extensión. Ha liberado el procesador y la ram rápidamente, y tiene muchas opciones para poder configurarla a tu gusto. La recomiendo totalmente. Es brillante. Gracias a su desarrollador, y al equipo que la hace posible.

It stopped working a long time ago and extension is now abandoned.

I'm very impressed! This is the most effective way to free up RAM that I've ever seen.

Works as expected. Very useful for batter life and old devices with low RAM and weak CPU.
It is must given today's badly optimized and scripts entangled mess we call a web. Not so much from security POV but at least idle means idle again.
