Great for saving on RAM. I tend to have a lot of tabs open, so it's even better for multitasking, especially you configure the many settings as well. It's very customizable and I like that.

This extension has saved so many GB of RAM memory that I feel I have upgraded my computer.

Awesome extension for tab-junkies!

It's essential!

Excellent.

Removes the burden of a long-running browser: it's always as if started anew, regardless of how many tabs you have. Only the few recently-visited tabs are loaded and running, and all of the others got unloaded (just like a freshly started browser would have them). Really nice for machines without a ton of free RAM.

Useful, simple to use, high performance gain, and open-source. Highly recommended!
