One of the first things I do when I install Firefox is to disable the password save option. I have no intention of letting my username/password pairs get saved automatically for others to view later on.
In Google Chrome, to disable the save-password option, click on the little spanner icon on the top right (beside the address bar), select Options, click on the Minor Tweaks tab and select Never save passwords. If you want to view passwords already saved, click on “Show saved passwords”!
UPDATE: Commentator Jim has this useful information to add in the comments section.
Here’s a scenario no one has discussed.
1. Allow Chrome to import information from a previously existing Firefox installation
2. Look at Wrench(Spanner)/Options/Minor Tweaks/Show Saved Passwords
3. Select a site, then click “Show Password”
Your saved password from Firefox is displayed in plain text. Chrome has read your password from Firefox, then made it available to anyone in possession of your machine. Physical security is still the most important aspect of security! We really need the master password now!
