Password Storage in Firefox

I got to thinking about password storage in Firefox recently, and wanted to figure out if they are easy to recover.  A quick search led me to to Password Fox.  I tried it out, and recovered the password pretty quickly (under a minute, maybe under 10 seconds).

Next, i made up an account and stored the password.  Finally, using Password Fox I recovered the password, as seen here:


The passwords are stored in a javascript object notation (json) file.  I added a few line breaks for easy reading, but it is this:

I went back in and set a master password, and the same trick did not work.  So, I recommend using this 'master password' if you're going to let Firefox store your passwords (but don't forget it).

This is all covered fairly well on Mozilla's support forum.
