firefox: Enable tracking protection for normal session

Firefox 42 includes very interesting feature - Tracking protection. By default it is active only in the Private mode. When the Firefox team presented a new video that described the usage of the Memory tab in the Developer toolbar, they show that the CNN website normally consumes about 40 Mb of memory and with Tracking protection on it consumes about 10 Mb. If you want to enable this feature not only for the private sessions, but also for the normal sessions, you can do that by typing about:config in the address bar and changing the value of the privacy.trackingprotection.enabled to true: There is also a really interesting setting privacy.trackingprotection.updateURL, which means, that, I believe, you can host your own tracking protection list (See shavar project, blocking list format is here). When Tracking protection has blocked some resources, it shows a shield icon near the address bar. If you open the Developer console (F12 or Ctrl+Shift+K) you can see what resources were blocked: Together with AdBlock extension it could be a nice way to improve your browsing expierence.
