If you save your login passwords for certain website for easy access, you are at risk of having someone stealing your password with a simple technique.
You can try this within Google Chrome or Firefox with Firebug Addon.
Simply go into some website that you had your password saved.
Right click on the password field and click on “Inspect Element.”
The HTML code edit will pop out below your browser and highlights where password is located within the source.

You can now simply change:
type="password"
to
type="text"
Click on anywhere in the source page and you should see your password within that text field.
And finally, that is why you should not save your passwords within your browser.
