Are Yahoo accounts on the same computer connected at all?

Question

When I go into my account information "my profile" and on the right of the screen is "options" if I click on one of the options, such as calendar and/or personals, it turns purple, showing I went into there. My question is, if I go into another yahoo account... that's not mine, but we share the same computer...If I go into his "account information", his option icons are also marked just the same as mine...and there has not been any activity by him... Is there some sort of connection. I thought all accounts are separate. Why does that happen? Or do I have reason to believe someone is connected to my account?

I appreciate the help.

Answer 1

This just happens because the computer recognizes them as the same page.

Lets say the page is passwordchange.php

Your computer would make This purple on all accounts, but every account will change a different password. If you are so worried and want it to be blue, then clear your browsing history and private data.
