Works like it should.
The settings are a bit complicated.
I could have the option to have more than one set of criteria, before closing tabs. Eg. closing tabs after 20 min, when having more than 10 open, but also closing tabs after 10 min, when having more than 25 open.

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!!!

works fine for the most part, but as of a couple days ago youtube tabs won't automatically discard any more when first opened, which is what I mainly use this for. Other than that I've not had any other real problems with this.

Edit: I originally gave this a three star review for the above issue, but it turns out Auto Tab Discard is interacting with UBlock Origin in a weird way and it's only when UBlock is active that I have this problem. Not really much I can do about it, but also not really the fault of this addon, so I bumped the rating up.

Great idea! Unfortunately, it doesn't function or work properly as of June 6 2025

don't work

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
