Extremely customizable, convenient, and does exactly what you want it to and more. A great extension for saving battery and memory whilst retaining any information you have on these pages and won't put tabs to sleep that have important information on them. Great extension.

It's amazing! Exactly what I needed

This add-on saved the day. My mac fan automagically stopped spinning.

It's very great, but I just wish it could close all the discarded tabs automatically (if possible)

rất tuyệt với!

Might have left Firefox without this.

excellent context menu integration

simple and easy to use
