Note that Privacy Badger uses a browser history-dependent algorithm for blocking - when you first install it, it doesn't block anything because it assumes that third-party trackers are innocent until proven guilty. When it sees you being tracked on 3+ first-party domains by a third party, it either blocks or cookieblocks the third party. I wrote up a basic description of the algorithm here: https://github.com/EFForg/privacybadgerfirefox/blob/master/R...

So if you're testing Privacy Badger on a profile with no browsing history, it is bound to do worse than other extensions. You have to "prime" it with some browsing data before it's really effective.

I see, so this means results for Privacy Badger reflect a worst-case scenario. I've added links to the proper section in the Privacy Badger's README file.

So people who use incognito mode don't benefit much?

Unfortunately not, if you use Incognito by default (other than being able to see who's tracking you and toggle the settings manually). We could add a feature to optionally save data in Privacy Badger between incognito sessions (or use data from the non-incognito sessions to determine which sites to block in incognito sessions).

In Firefox, PBadger Alpha doesn't have permission to operate in Incognito mode yet, so it will just be off.
