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.
