erm this is not really the case, this program's trick is actually instead of using your ram to manage firefox, it runs it in a virtual memory. if you've got a powerful CPU (which most modern pc's have nowadays) then it might not be noticeable at all that the workload have been transferred to the CPU instead of the ram. but do this on some pretty laid back jurassic pc, hoho the cpue will suffer. but then again, it won't hurt you to try... maybe this image will explain what i'm saying clearer: [align=center][img]http://img258.imageshack.us/img258/8368/39503971nf2.png[/img][/align]
