Don't work

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. ***

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

Tabs with videos being played through the pop-up window get discarded and this even after I have white-listed the domain!

Broken, whenever a tab is discarded and i click on it it goes back to the "new tab" page as if i just opened a fresh tab, also cant go back to the tab were i was with the "Go back one page" feature (the arrow)

Not working at all since Version 0.6.2. Have to revert to 5.0 to fix as other review mentioned. Once this issue is fixed on current version rating will improve.

The exceptions don't work, keeps closing my youtube tabs.

Some tabs do not get recovered bot vanish when I click on them which is an absolute no go! Also I personally do not like the emojii or custom title prefix to mark sleeping tabs, the greyed out title was easier to recognize.

Не работает.

Doesn't work, even if trying to discard manually.

Used to work fairly good, but since the last update, tabs don't discard and I haven't changed my settings any from previous versions I used. Had to uninstall. Disappointed.

Switched to a new tab to look something up while working on a new post to reddit. Previous reddit tab was discarded by Auto Tab Discard and upon return the title remained, but the text box was cleared. Absolutely unacceptable loss of time and effort that makes me question how safe this extension is to use anymore.

I found it not very useful as it doesn't discard tabs just marks them as inactive. That however isn't the issue. Upon removal it forces you on addOn.com for feedback and opens a tab with this which I find hugely invasive and quite bad taste.

Doesn't do anything. Garbage.

edit: Protip: use Tab Wrangler instead. That one does work and it's easy and intuitive.
