This extension has been a lifesaver—it helped me fix all the memory leak issues I was having on YouTube.

Works as expected. Very useful for batter life and old devices with low RAM and weak CPU.
It is must given today's badly optimized and scripts entangled mess we call a web. Not so much from security POV but at least idle means idle again.

This addon is beautiful and a lifesaver and I love it.

My only gripe is that the name and "discard" terminology is misleading; I'd have tried it way sooner if not for that.

A must-have extension for anyone who opens a bazillion tabs all at once, and probably even for people who only open a few (since it doesn't take all that many before Firefox begins to slow, even with fast PC).

I don't know why Firefox doesn't handle unloading tabs even half this well natively, but it really doesn't. Firefox runs so much better with this installed.

I appreciate the detailed options very much, as well. You can customize it to your liking.

this has just saved me from losing over 300 tabs right now

I wouldn't be able to always have 50+ tabs open if it wasn't for this, pretty good

This extension is awesome for keeping my browser fast and my laptop battery lasting longer. It automatically puts inactive tabs to sleep, freeing up memory and reducing CPU use without closing anything. When I switch back, the tab just reloads right where I left off. It’s super lightweight, easy to use, and works quietly in the background. Perfect for people who keep lots of tabs open but don’t want their computer to slow down. Simple, effective, and really useful.
