Sigh. I was worried this would happen. I know Mozilla need to make money and with their market share shrinking that is getting harder but these kind of "features" put me off wanting to use Firefox all together. I would rather use Chromium over a version of Firefox with targeted advertising built in.

For now at least it looks like being able to disable it is still possible but I cannot find any mention if disabling this also disables the whole analysing my history bit?

There's no real analysis of your history, it's just selecting the top visited links (using existing code, which is used to show you the current tiles of visited sites).
