Pretty good.
Maybe not as sofisticated as similar addons I´ve used in the past, but it does well the main task.
My main issue with it is that as soon as it suspends a tab that I have bookmarked, the bookmark itself becomes grayed out, for whatever reason, so sure but slowly many of my bookmarks a looking "weird". Not that big an issue, though.
Thanks!

I have only one gripe with this extension, and it may be unavoidable (for all I know) given the method it uses for "suspending" the tabs. When I close a tab that is to the left of a suspended tab, the suspended tab immediately becomes active again. I would prefer the tab remain suspended until I click in the browser content area.

Thank you so much, this is an absolutely awesome extension, it works great and should be integrated in every web browser !

Work as intended, with great options for customization. I wish, though, it was more visually clear that a tab was discarded (I find the grayed icon hard to read). Thanks!

It stopped suspending after i turned off thenn upon reuse it wont suspend. biggest problem is i lose urls & cant reload those. im on ff60.0.1 plz help me, thx!

Without this add-on, Firefox has become an unwieldy, slowly dying wind bag. It will suck in 6GB of memory in a handful of hours, with heavy browser work. That's because of the tons of scripts and media being run on your computer. Even NoScript is not a good alternative, because it's very cumbersome - even if you use it for safety. Just be sure for ATD, that you spend a few minutes in OPTIONS (Tools / Plugins / ATD - Options) because you'll be consuming A LOT of bandwidth needlessly RELOADING stuff you're in the middle of. I am currently using 1,800 seconds before discard (30 min.), instead of the default 600 (10 minutes.)

Does what it says

This is nice, and works very well. I'd like for an option to temporarily disable auto discarding, though, since there are a lot of times when I work with a lot of tabs and I'd like to have all of them available. Thanks.

Auto Discard would be great too! And ofc s/discard/suspend/.

Even better than it's predecessor!!!

Para ordenadores con poca memoria ram es ideal. Tambien para aquellos que mantienen abiertas múltiples pestañas simultáneamente. Los ajustes son variados y adecuados.

The exception with "re" seems not working.

Powerful! So glad to regain control of my CPU from poorly written web pages running in the background!
