One of Firefox’s most convenient features is its ability to save the passwords you use to log on to web sites – like your webmail and online banking – so you don’t have to type them in every time. Those saved passwords appear as asterisks in the password field, but did you know how easy it is to see what they are? In Firefox, from the Tools menu, choose Options, and in the Passwords tab hit the “View Saved Passwords” button. Then hit “Show Passwords.” Yup, there they are, all your high security passwords in plain text and full sight. I kid you not.
Try it. Right now. I’ll wait.
Now consider how easy it would be for your Firefox-lovin’ housemate to log onto your Gmail, or the computer-sharing temp at the office to get into your checking account or your other half to discover all your pr0n site logins. (Ok, we’re just kidding about the porn. Maybe.) Not such a great feature anymore, eh? Today we’ll go over a lesser-known feature in Firefox which secures your saved passwords without requiring you to give up the convenience of those autofilled login details.
Back in that password dialog (Tools menu, Options, Passwords) there’s a “Change Master Password” button. This master password is a SINGLE password that will unlock the rest of your saved passwords from prying eyes. It’s a password you’ll have to enter once a session – so each time you restart Firefox.
