I found I have some sort of exploit which takes screen captures whenever I click on any web page. It is specially active whenever you are entering sensitive information like when I log-in onto site accounts, o whenever I check something on the bank. I checked processes using process explorer, and everything points at Mozilla being very active and nothing else. I check the creation of those screen captures and they are always, there. I ran several bootable antivirues like Eset, Kaspersky and Bitdefender and they don't detect anything weird. I removed all temp file this "thing" creates while making files and take snap of my screen. I also disable all Firefox add-ons, as well as the Java on my computer -I believe there's some connection with Java here-. So there, guys!! I don't know where this "thing" resides,
