An interesting approach. Does it block localStorage?

Currently not. I regularly check my localStorage and I've never found anything that doesn't belong there. It seems that this is not in widespread use for tracking. I might add that feature when the situation changes. Unfortunately, the API that Firefox offers to work with localStorage is nowhere near as comprehensive as the one for cookies. Implementing this *efficiently* might be problematic if it doesn't improve.
