In sounds like you have Firefox's fingerprint resist feature enabled. This confusion occurs every time this topic comes up because there are two different strategies used to attack the problem and people end up measuring them both the same way.

You can try to be so generic that the attributes are meaningless, the meatspace version of this would be everyone wearing a Guy Fawkes mask so they all have the same face and you can't tell the difference between individuals. Or, you can wear a new generic face every single day so that nothing you did yesterday connects to you, an bland ephemeral identity.

Tor uses the former method (or tries to), everyone is up to something but you can't tell them apart because they all have the same face/browser attributes. Firefox's fingerprint resist is the second method, normally identifying values are fuzzed repeatedly so that while each signature is identifiable you won't be using it for long enough to connect them to eachother. Both strategies have their merits.
