How do I disconnect Facebook from Yahoo E-Mail?

[IA]

My Contact List is huge because Yahoo is saving anyone I've ever e-mailed or has posted on Facebook. I DON'T WANT THESE MADE INTO PERMANENT CONTACTS. How do I stop this and/or disconnect Facebook from my Yahoo emails?

Permanently deleting your account///deactivating your account
Facebook offers an option for those who want their account deleted with no chance of recovery or deactivating it. These options are only accessible in this link, which is provided in the Facebook Help Center when you type “delete my account” or "deactivate my account" in its search box.

Once you have opened the page of that link, you must click on the Submit button and then, on a pop up box, you must enter your account password and a captcha text. Once you are done with that, click Okay. Facebook will ask you to confirm the action, so you will have to click on an Okay button again.

When you delete your account your things will disappear from Facebook once you have done that, to finish the deletion process you will have to avoid logging in to your account during the next 14 days. After that period of time your information will be no longer available, never again.
Steps for the deactivation of your account is also explained in this area.
