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.

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!

Simple and works really well, automatically makes a huge difference. Runs faster and does not crash. I use it so inactive tabs are there but "go to sleep".
