Is Privacy Badger still necessary for people that already use ublock and its own tracking filters?

ublock is great software (it didn't exist when we started work on PB!) and so there are only a few things PB will catch that it doesn't. But there are some. For instance, PB will replace widgets such as Tweet and Facebook like buttons with locally hosted, non-tracking variants. And PB may catch new trackers faster than ublock because it uses algorithmic detection rather than requiring a blocklist.

You can use Privacy Badger on sites that you want to support with ad views (as long as those adds don't track you).

A good example of this is many of the webcomics I read. Many of the adds on those sites are for other webcomics, I've found a couple of good new webcomics that way.

Much better to simply buy their merchandise instead.

Yes. I use both ublock origin and privacy badger and for the majority of sites both plugins detect and block stuff.

Any idea what's the difference between Privacy Badger and Self Destructing Cookies addon? I would think SDC will also stop any tracking by deleting the cookies?

Privacy Badger currently detects tracking via regular cookies, HTML5 local storage 'cookies', and canvas fingerprinting, with more methods aimed to be supported in future releases

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]

As many as we can implement! Pull requests are welcome :)

Good starting places for the current heuristics:

It won't currently block most of the evercookie tests, since it currently only targets 3rd-party tracking.
