Both of these tools are focused on cross-site ("third-party") tracking, rather than cross-session tracking by an individual site ("first-party"). Third-party tracking is technically easier to try to detect, and some people regard it as more intrusive.
As I mentioned upthread, EFF's own research on browser fingerprinting shows that it's hard to stop all user tracking (because your browser and OS and device might be different enough from others to be unique in a population in ways that could be observable by a remote site). Tor Browser is doing great work on this
and I think they've made concrete progress. (I think the Tor Browser developers might say that the privacy benefits of using their changes without Tor are unclear because you could also so easily be tracked by IP address. But it's possible that some of their changes will find their way into mainline Firefox, at least as options.)
