With only 4gigs of ram this add on made all the difference. Usually when I ran out of memory from having too many tabs open the computer became unusable. With this add on that never happened again!!!

Great functionality, reliability and options for customization. Frequent and useful updates. Has made my internet use more productive, efficient and enjoyable. An all-time favorite.

One of the most useful Firefox extensions that I use. Combined with Simple Tab Groups makes my FF really lightweight, allowing having opened just the tabs I need.

A great, simple, and lightweight extension to discard multiple tabs. It has great features and easy to follow options. However, I'm not a fan of the latest update that changes the gray dot and grayed out tab when discarding a tab to the blue "zzz" icon and not graying out the tab. I prefer the former because it's easier to tell which tabs have been discarded. The blue "zzz" icon is also a bit distracting.

una extensión clave para gestionar a gusto el navegador, tanto en computadoras de altos y bajos recursos.

I keep a lot of pages hanging as I would like to easily find them back later while doing research, and thanks to Auto Tab Discard they do not all keep running throughout the study session, freeing up speed for my browsing experience :) Works well with Tree Style Tab!

I never use browser without this brilliant tool + Onetab, Thanks guys!

It works, has every setting you could think of and visually indicated inactive tabs. For some reason the add-on does take up quite a bit of resources as seen in about:performance. And it also needs every permission you could think of....

Wow. What a memory saver.
