Where are the Windows Registry locations of Google Chrome and Firefox when we set "block third party cookies" on browser?

Question

Where do Google Chrome and Firefox store there registry values when we set "block third party cookies" on browsers

1. Chrome (chrome://settings/content/cookies) and
2. Firefox (about:preferences#privacy)?

I'm trying to handle for option "block third party cookies" on browser Chrome and Firefox by editing there corresponding values in registry. However, I cannot find the location of registry entry which handle for "block third party cookies"

I searched on the internet and I found some directions for this:

• For Chrome: [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]
• For Firefox: [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\lockedpref]

But I cannot find these directories on my PC and another PC, I also reinstall Chrome and Firefox with the newest version.

However, I can find and handle for the registry value of IE and Edge:

• For IE: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3]
• For Edge: HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\MicrosoftEdge\Main

Could you please tell me where are the locations of them on Chrome and Firefox?

Answer 1

They are not in the registry. Organization policies still are however.

In about:config

network.cookie.alwaysAcceptSessionCookies = false Disables acceptance of session cookies.

network.cookie.cookieBehavior Disable cookies. 0 = All cookies are allowed. (Default) 1 = Only cookies from the originating server are allowed. (block third party cookies) 2 = No cookies are allowed. 3 = Third-party cookies are allowed only if that site has stored cookies already from a previous visit

network.cookie.lifetimePolicy cookies are deleted at the end of the session 0 = The cookie's lifetime is supplied by the server. (Default) 1 = The user is prompted for the cookie's lifetime. 2 = The cookie expires at the end of the session (when the browser closes). 3 = The cookie lasts for the number of days specified by network.cookie.lifetime.days.
