Firefox clear text password later use to be careful _ Application skills

Firefox's plaintext password is a problem
Last night in the settings Firefox, accidentally found this let me quite surprised by the function, through Firefox can actually see I have logged in all the site password, and are clear, without any encryption. I wonder if we have ever noticed? At least I didn't know Firefox had this feature before.

Enter the "Tools –> option –> security –> display password –> display password", screenshot below.

In addition, I Google a bit, there is no way to shield the "Display password" feature, unless you use the "Master password", but may cause you a lot of trouble. Anti-view IE, it does not provide a password to display the problem, but in fact can see IE save password software is also flying, the same is not safe. So in the final analysis, personal network security and protection still need to keep in mind, try to avoid others to use your personal computer.
