Rated 5 out of 5 stars

Works very well. My memory used to go as high as 1,500,00, and now RAMback keeps releasing memory after closing tabs and it is around 650,000. It works in the background, the user doesn't need to do anything. If you want to watch it work, bring up Windows Task Manager and watch firefox memory before installing and after installing. Watch how the memory goes up after opening tabs, and how it is released after closing tabs. Firefox did not do that before installing RAMback. I am using Flash Control addon for stopping flash. Do not use "Youtube Flash Player" addon with "Flashblock" addon, it seems to make things worse.
