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.

Very useful add-on ! Works perfectly ! Only thing I'd like to see, is the option to not reactivate automaticaly a tab whenever you click on it : I sometimes happen to missclick on the wrong tab I need, and thus activate the wrong tab

Tried to make Firefox faster by discarding my hundreds of other tabs, but those seem to be turned into ash now instead of reloading on click.

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!
