Mozilla Firefox 42 has been released.
In this version, Monica Chew's cross-site tracking protection (announced 10 November 2014) is now enabled during private browsing mode. Previously, the feature could be turned on by configuring privacy.trackingprotection.enabled via about:config—a situation which led to a ZDnet editorial criticizing Mozilla for a "lack of commitment" to the feature. Tracking protection blocks loading of elements from the third-party sites that are included in a blacklist from Disconnect. Besides hindering tracking, it is said to significantly reduce the load times of some pages. The blocked elements can include "analytics, social network buttons and display advertising."
The new version also corrects 17 security flaws, better indicates a site's security, and adds tools for animators.

Why trust an external party when you can use something like Request Policy to block most of the tracking crap. Yes, it can take some time for some sites to get things configured to load properly, but you have full control of what is getting loaded.
For me, Request Policy and NoScript are essential addons. With them, I do not bother with ad blockers.
I disabled the use of tracking protection when upgrading to 42.
