FireFox inherited a small security update from the Tor project called "First Party Isolation". It's in newer versions of FF, but isn't turned on by default as it can break some authentication systems.
What it does, is only allow cookies to be sent and received by the site in the page's URL. So, for instance, while visiting YouTube.com, images and the like from google.com can load, but have no cookies attached, and do not receive those cookies.
To enable it, go to about:config and find "privacy.firstparty.isolate". Set it to true and restart the browser, and enjoy surfing the web knowing that you're not being tracked from site to site.
