Great addon to save your computer resources. Low on RAM or want to cut back your CPU usage, try this addon. Will suspend tabs in the background, freeing up RAM and using less CPU resources.

4/5 stars because there is one small bug that if you click on a discarded tab right after it's discarded, the page will fail to load. Fixed by a quick refresh.

Works great, but I'm worried that it hasn't been updated in two years.

This add-on works very well for improving performance, is easy to use, and has lots of customization options. However, one feature that it's sorely missing is the ability to view a tab or bring a tab into focus without un-discarding it. This is a major issue for me because I scroll through tabs to navigate my browser, so I end up loading a bunch of tabs I don't want to load. If there was an option to only un-discard a tab when I click in the tab instead of when I open it, this would be perfect.

В целом хорошо.
Из нюансов:
1. Значок 💤 отнимает полезное пространство и не так хорошо сигнализирует как если бы сама иконка сайта становилась серой, как в The Marvellous Suspender, например. Иногда возникает путаница если 💤 эмодзи присутствует в названии сайта.
2. Скорость загрузки выгруженного сайта занимает много немного больше времени, чем ожидаешь и этим раздражает.
3. Большая нагрузка при выгрузке и попытках выгрузки сайтов расширением. С включением данного расширения появляются периодические подвисания системы.

As Firefox gets greedier and greedier with memory use (not to mention memory management bugs that never get fixed by devs) it is nice to be able to put unused tabs to "sleep".

Only 4 stars because the White Listing of tabs to keep them awake doesn't seem to work for me any more.

useful and helpful in reducing memory and CPU load on my aging PC.
Wish there was more flexibility with session keeping. for example, I'd like all the tabs of this current window to stay active for this session.

你测

There could be a setting to delay the release of left and right tabs discard, for when you are just checking the active tab back and forth, and for when you really know you want the active tab, but loading the left and/or right tab(s) makes it take longer.

Very useful add-on ! Works perfectly ! Only thing I'd like to see, is the option to not reactivate automaticaly a tab whenever you click on it : I sometimes happen to missclick on the wrong tab I need, and thus activate the wrong tab

Good extension, but needs better defaults. E.g. "Do not discard a tab when it is pinned" should be ON by default.

In the latest 0.6.3.2 version of this plugin, the tabs that have reached the hibernation time cannot be automatically hibernated, I returned to the 0.5 version and it was fine. I am using Firefox Developer Edition 106.0 Beta 6 (20220929195234)

for those people who have problems that the addon suddenly doesn't work anymore, revert to version 5.0

i dont know what update dev made but it made the addon useless, cant use discard in any options even with keyboard shortcut. once you revert back, it will work once again.

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。。
