It was highly recommended in other browsers, although Chrome / Chromium already has Memory Saver (://settings/performance OR ://settings/system etc.) and even Opera has known this for a long time... And Firefox's great strength is, in principle, precisely the so in principle, this plugin should not be used to manage tabs, but since Firefox has been consuming an unusually large amount of memory recently, I tried it for testing and *** the browser was successful: new tabs were no longer loaded, the little dot moved here and there. Inactivation was not enough, the "ZZZ" icon was violently displayed on the tabs! I removed it.
And since then the ears have not been filled. "Damn good." Must reinstall. ***

ГЕНИАЛЬНО ВОСХЕТИТЕЛЬНО .. главное чтоб комп не згорел : ) .. это решение давно висело в воздухе.. aLoha

The addon no longer works properly, it no longer disables tabs.

Great for saving on RAM. I tend to have a lot of tabs open, so it's even better for multitasking, especially you configure the many settings as well. It's very customizable and I like that.

This extension has saved so many GB of RAM memory that I feel I have upgraded my computer.

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
