How to disable third-party cookies in Firefox 3.5?

Firefox 3.0.x had the option to never accept third party cookies, but 3.5 RC doesn't and fails a test of whether the browser accepts such cookies. Seeing as I cannot think of any good reason to keep third party cookies enabled, how can I turn them off in 3.5?

(Or, seeing as Mozilla insists on stupidly removing important settings options like this, should I just switch to Chrome?)

 

This is from Firefox 3.5

 

I use CS Lite add on. this way you can block 3rd party cookies and global cookies and create a white list of sites that you need cookies for.

 

My experience is that a new install of FF 3.5 where none has ever been before or an install after a complete uninstall of 3.0.12 gives the unhelpful default of "Remember history," which shows none of the cookie management options everyone is used to from earlier versions of firefox.



Again, in my experience, simply installing OVER ff 3.0.12 or after uninstalling 3.0.12 but leaving all my user data intact (the usual uninstall prior to a ff upgrade), gives the "use custom settings for history" that others have shown above. Your mileage may vary.

Thanks to those who showed those screenshots. Some of us saw the other options but lacked the curiosity at first to try them.

And yet...why would Mozilla change the default to "don't show the user anything powerful"? You might as well do something like defaulting Windows OS versions all the way up to 7 RC to NOT show file extensions. Oh, wait, that's been done, too, hasn't it.
