Very useful, save a lot of RAM.

After evaluating this for a couple of days on a desktop and laptop (Ubuntu and Fedora), this works as expected. The settings are nicely configurable. Restore a discarded tab has so far worked very well.

В диспетчере задач браузера показывает очень большое потребление процессора.Похоже на майнер.😡

there is a problem that when saving the changes made in the option does not take effect instantly after saving. you need to restart or close down all firefox processes before the changes takes effect.

another would be it does not discard pinned tabs (discord,twitter,etc) on browser startup even if the option was checked.

these two were my only complaint since these were working before

settings page is a complete mess and exact funtionality is very unclear. immediately suspends some tabs as soon as they're clicked away from, never suspends others.
