I need to recover a typed password in my laptop. I use Mozilla Firefox and I think that maybe it can be done by reading cookies, if possible, or maybe the cache memory?
OMG... Help!

Normally if you typed a password in Firefox, the first thing it does is ask you if you want to save this password, if you select yes, it autofills it in every time you go to that page, if you select no, it isn't stored at all.
