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.😡

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.

Вполне приложение меня порадовало понравилось как быстро загружают страницы браузер много разных фишек в этом браузере рекомендую всем!

The description makes claims that are not so true in the current FF environments (other unloaders don't actually unload) that are easily verified in about:performance and about:memory. Checking those, one can see if the other unloaders work or not.

Annoyingly it does something no other unloader I have tried so far does, marks every tab it unloads as 'updated' in the same way as if the tab had an autorefresh or notification. This makes every tab it unloads look as though a message is pending if you highlight such in any way. UNLOADING SHOULD NOT MARK A TAB AS UPDATED!

Last it misses tabs that based on the setting should most definitely be unloaded. Sometimes even duplicates of the same tab (thus confirming no rule conflicts as it unloads some but not other duplicate identical content tabs).

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.
