FireFox users are a funny bunch. We think that we are more secure, and generally that the Mozilla foundation takes care of us better than Microsoft is willing to. For the most part this is true and what I am about to expose does not dispel that belief at all.

Do you use the Remember my password feature in FireFox? Do you realize your passwords are stored on your HDD in an unencrypted state? Does this bother you?

It may occur to you that someone would need physical access to your machine to use that information. right? No. You could be the victim of a virus or trojan etc.

You may say that you password protect your computer, so no one can log into it but you. But what about when you sell your computer? What if it is stolen. I can boot linux and mount your HDD and access all that data.

I was unaware of this and DLS did a good job of explaining the concern:

So I still use KeePass, I still use the remember my password feature but now I enter a really good password to get to that data.

It is easy. Just open your options in FF and find the area to protect your passwords :)
