If you try looking for the Lightbeam download link by doing a Google search, you're going to end up at Firefox pages saying "Not Found".

I downloaded Lightbeam from the link below. https://addons.mozilla.org/en-US/firefox/addon/lightbeam/

In Firefox, I run

DoNotTrackMe

Disconnect.me
https://disconnect.me/

Ghostery
https://www.ghostery.com/

They each do similar blocking of tracking cookies, but they each seem to have unique features/blocking.
