Add Decentraleyes to slighten off a bit Exit traffic and work around some CDNs blocking of Tor
For those who don't know what it does: "Protects you against tracking through "free", centralized, content delivery. It prevents a lot of requests from reaching networks like Google Hosted Libraries, and serves local files to keep sites from breaking. Complements regular content blockers."
That way not only some sites will load slightly faster (or faster for low-bandwidth clients) due to the resources being blocked and loaded locally (which also means slightly less traffic needed for exits), but also will protect from tracking by those CDNs.
This addon doesn't clash with section 2.3. of the Tor Browser Design Doc with regards to ad-blockers as it isn't one.

This risk (that it greatly speeds the rate at which an adversary watching a few exit points — or heck, a few ad sites — will be able to observe a given user's exit traffic)..."
