Not really. For one, anybody that can use your computer can see a plaintext list of your Chrome passwords directly from the Chrome options menu. It's an incredibly primitive system.
this part though we usually have good defense against. how many people are using your computer? do you have a login with a password? do you have FDE? when was the last time you handed your laptop over for someone to use without you being right there?
the browser password managers are good enough for most uses
