Brilliant, absolutely a must-have, indispensable add-on. It can easily save up to 3 GB of RAM on a typical browsing session. This is a game-changer for heavy multi-tasking.

很好用，不過最近在firefox nightly 91.0a1中，會有沒辦法在分頁上點擊右鍵，在選單中休眠其他的或左側、右側分頁，希望能早日修正，現在只能點選套件的圖示，來進行休眠分頁

With only 4gigs of ram this add on made all the difference. Usually when I ran out of memory from having too many tabs open the computer became unusable. With this add on that never happened again!!!

Great functionality, reliability and options for customization. Frequent and useful updates. Has made my internet use more productive, efficient and enjoyable. An all-time favorite.

One of the most useful Firefox extensions that I use. Combined with Simple Tab Groups makes my FF really lightweight, allowing having opened just the tabs I need.

una extensión clave para gestionar a gusto el navegador, tanto en computadoras de altos y bajos recursos.
