The second feature automates the process for you. You can set a timeout interval after which the active tabs get unloaded automatically to free up memory that they have occupied.
Firefox used about 220 Megabyte of RAM while running with the extension installed and active in the browser. And that’s with more than 50 tabs open across two browser windows. If you run Firefox without the extension you will notice that it uses more RAM over time as more tabs remain active in the browser. If you are noticing a high memory usage it is more likely that it is caused by an extension or plugin installed in the browser.
