What other tracking methods does Privacy Badger plan to block in future releases? One can always test against evercookie.[0] And perhaps EFF could host a trustable demo site, along the lines of Panopticlick. I do get that this is an arms race, and that proprietary methods may be running under the radar, as Verizon's UIDH did for two years.[1]
