When you type a password into any web form, both Internet Explorer and Firefox prompt whether you would like them to remember your password.
If that’s a personal computer, chances are high that you will click Yes and the password is then saved in the web browser.
This “Remember Me” option in web browsers is useful but it actually puts your login credentials at serious risk especially in Firefox.
I should note that Opera should be included here as well, as it has the same option.
