I am concerned that if my computer falls into wrong hands that somebody could remove and read the SSD and find remnants of my financial website passwords. To my understanding Firefox may place website passwords in temporary storage on SSDs and not overwrite them (hard to do on SSDs). I don't want to completely encrypt my computer, because it is slow. I use a password manager so that I don't store financial passwords in Firefox storage, but I do have to type them in to access financial websites. My suggestion is to have Firefox temporarily store typed in passwords only in RAM, since it goes away, when I restart my computer
