Great add-on. However, the last few weeks I've noticed an error of some kind. Reawakened tabs will not be on the last page I was looking at, but rather the page ~30 min. before it auto discarded. This makes the add-on borderline unusable to me.

very good!!

free free ram :)

建议把工具栏按钮的弹出菜单改为显示当前标签的休眠倒计时，，，或者是标签列表休眠倒计时。。

Must install for mega taskers. Before quantum upgrade to FF there was lots of addons to manage memory and features. Then as firefox became like every chromium based browser and as bloated I didn't find anything until this.

Avg mem usage went from 75% of my 64gb of ram to 25% enough said.

Would like to see more functions with add-ons like tree style tabs in the future.

جربتها قلت ممكن يكون الاتصال اسرع اذا نامت صفحات الاعلان لكن نفس تقطع الاتصال

Amazing save Ram and cpu usage ! keep update! واقعا عالیه مصرف رم نصف میکنه اتوماتیک بعد از 10 دقیقه 6 تب به حالت خواب میبره

I am now so exicted that this extension acutally works!! Cannot believe it! I don't know anyone out there is like me always have over 50+tabs opened. You said that is what bookmarks for? Nope. Let me tell you, if you put into the bookmarks you will just forget it. If I keep them opened, I will notice them, and never forget what I left whether or not need to continue or finisht it. Before using the extension, my Firefox always ate up 16+GB memory, I needed to upgrade my PC memory to 32GB, as I am also a programmer working with different platforms that use heaps of memory. After I install this extension, my Firefox only uses 1.6GB, 10 times less, I am not joking. Cannot be happier to find the extension. The only thing that can be improved is if there are more explanations on each option would have been better. I don't know why Firefox team cannot do it...after so many years...
