It will be more nice if you guys add a keyboard shortcut also!

I have a bad habit of have dozens of tabs per window and multiple windows open . . . as anyone who uses Firefox knows that ends up taking a large toll on your computer resources. I was so grateful to find his add-on and it is an invaluable extension for Firefox! I highly recommend it to anyone who likes to have a huge number of tab opens and still wants to be able actually user there computer.

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.
