Quick Help: Change Firefox settings to evade tracking through cookies

16. Jun 2012

I already informed you that your browser will accept cookies from wordpress.com and third parties in it’s standard configuration. Some cookies expire soon, while others expire in the far far future. With the cookies on this blog it’s more the latter.

 

Disabling cookies entirely

You certainly could disable cookies completely, but it breaks functionality on some sites, since cookies are used for authentication and to remember settings you made.

Open the Firefox preferences and go to “Privacy” and change the setting from “Remember history” to “Use custom settings for history”.

Unhook “Accept cookies from sites”. Note that “Accept third-party cookies” is unhooked automatically then. Close the dialog by clicking OK.

 

Disabling third-party cookies, only.

I’m currently not aware of a site that relies on third-party cookies in terms of authentication or that designed critical functions around it. It should break sites far less.

Note that in this case only the domain you visit (e.g. wordpess.com) could set a cookie.

Open the Firefox preferences and go to “Privacy” and change the setting from “Remember history” to “Use custom settings for history”.

Unhook “Accept third-party cookies” and close the dialog with OK.

 

Change the cookie lifetime.

Cookies can be required at some point so you have to allow them to use a service. In this case you can change how long cookies will be kept.

Open the Firefox preferences and go to “Privacy” and change the setting from “Remember history” to “Use custom settings for history”.

Change “Keep until:” “they expire” (which can be pretty long) to either “prompt every time” (pretty annoying) or “Firefox gets closed”.

“Firefox gets closed”, means that all cookies will be deleted when you close all instances of Firefox.

 

It’s up to you to combine these ways. For instance you could set all cookies to be kept until Firefox is closed (what I would recommend) and don’t accept third-party cookies.
