It works very well and what I like most is that the add-on behavior is very customizable.

its like marvellous suspender for chromium browsers but works better in every single way (for me). I had a lot of time consuming issues with various suspender versions after the official one died and swapped to firefox a few months ago, this one JUST WORKS! big fan.

I can now play while having 70+ tabs, very simple, nice, useful, thanks!!!

Az újabb Firefox nem kezeli jól a memóriát és elképesztően sokat zabál (belőle) így aki úgy használja amiben ez a böngésző eredetileg a legjobb volt, tehát sok ablak = lap = fül = tab akkor ez neki való mert az inaktívak nem használnak memóriát és így végre újra a régi az élmény.

Perfect for my 8gb ram laptop.

Very good work! This extension effectively reduces the RAM usage. Among all these extensions with similar function, Auto Tab Discard works best and is the most configurable.

The best memory saver I've ever used!

I'm a little bit of a tab hoarder... And that results in all of my 32GB of RAM filling up all the time. Then I need to close the browser and open it again, to free up my RAM. My next planned step before knowing about this extension was to buy more RAM.

But this extension fixes the problem. All tabs that are not used just get their resources freed after some time. How this is not a standard feature in Firefox baffles me... So it goes without saying; This is a great extension!

Lightweight and useful

I've found Auto Tab Discard very useful for many years. It keeps my browser running smooth, even when I've got upwards of 400 tabs open.
