Firefox can block tracking cookies- but not by default

I read an article on the BBC News website about ad blocking in web browsers recently and was interested to read a claim that blocking tracking cookies in Firefox can speed up page load times by about 44%. Whatever you may think about the privacy concerns of tracking cookies, this seems to be a big hit on performance. The article doesn't mention how to activate tracking protection in Firefox (it's not enabled by default, or an easy preferences option), but the information is available on this Mozilla Support page.

This feature requires a recent version of Firefox to work- the ESR version in Debian Jessie didn't support it. I had to install the release version from the Debian Mozilla Team. As a bonus, I get to play with the new video chat feature, and preferences in a tab.
