Prevent Facebook Snooping After Logging Off?

Disabling Facebook Cookies

My Goal: I do not want Facebook to receive personally identifiable cookie information when I am logged out of Facebook under my Google Chrome web browser. I do not want cookies associated with the web browser of Facebook to remain active after I have log-out of Facebook.

Which of the following configuration settings shown below using Google Chrome must I turn on or off or remove or otherwise. To prevent Facebook from keeping tabs (spying/snooping) on any of my web activity after I am logged out of Facebook?

Under Google Settings Under Cookies:

chrome://settings/content/cookies

Allow Sites To Save And Read Cookie Data (On or Off)

Keep Local Data Only Until You Quit Your Browser (On or Off)

Block Third-Party Cookies (On or Off)

Then I am given ONE of the three following options:

1. Block Sites: Add A Site (Optional); Do I add Facebook here (Yes or No)

2. Clear Site Cookies On Exit (Optional); Do I add Facebook here (Yes or No)

3. Allow Sites (Optional); Do I add Facebook here (Yes or No)

All Cookies And Site Data (Remove All Shown - Option) (Yes or No)

Facebook - Eight Cookies Current Shown (Locally Stored Data): Do I delete (Yes or No)

Facebook - Cache Storage, File System, Database Storage, Local Storage: Do I delete all (Yes or No)

(End)

My thoughts

Quote (cut and paste), my answers in bold.

Under Google Settings Under Cookies:

chrome://settings/content/cookies

Allow Sites To Save And Read Cookie Data (On or Off) - On as you don't want to keep flipping to this setting and some sites need their cookies to work properly. You can always experiment.

Keep Local Data Only Until You Quit Your Browser (On or Off) - OFF - This is your call but if you delete all local data every time you close chrome you lose the benefits of cookies to remember specifics. It does get rid of all tracking cookies but things like keep me signed in don't work.

Block Third-Party Cookies (On or Off) - ​Off, if Facebook applies a cookie to work then you don't want one from some affiliate or third party. I always run with this off. Even with off Tracking cookies get stored somehow.

Then I am given ONE of the three following options:

1. Block Sites: Add A Site (Optional); Do I add Facebook here (Yes or No) - This is to Block a specific site, you can try blocking Facebook and seeing if it works. Not sure that all cookies that may get stored have Facebook in name which would defeat this setting.

2. Clear Site Cookies On Exit (Optional); Do I add Facebook here (Yes or No) - This deletes specific sites, guess this would work if you knew all cookies had facebook in name. Again I block third party but still get a list of cookies from places I didn't visit.

3. Allow Sites (Optional); Do I add Facebook here (Yes or No) - This says you will allow cookies when on a site. I assume this is used if you answered no to very first question about allow sites to store and read.
All Cookies And Site Data (Remove All Shown - Option) (Yes or No) - This section allows you to delete specific cookies, way to much work to enter everyday and delete and even more challenging to know what others to delete. If you delete all I know some sites that use keep me signed in won't work. Maybe you store passwords so not as big an issue.

Facebook - Eight Cookies Current Shown (Locally Stored Data): Do I delete (Yes or No) - Couldn't hurt but you will have to sign in on next visit

Facebook - Cache Storage, File System, Database Storage, Local Storage: Do I delete all (Yes or No) - I see no harm, I remove all stored data every so often.

(End)

I think what you want and would be way easier to administer is run in Incognito mode. CRTL + Shift + N. Then use Facebook and when you are finished close the window. Nothing is supposed to be kept, history, cache, cookies etc.

Pretty much every browser has a private mode.

Adobe Flash can also store "cookies" and you have to delete them in a different process. Not sure if Facebook uses any Flash.

Lets see if other members agree with my definitions and suggestions.
