Recent versions of Mozilla offer an “offline cache” that web applications can use to store data for retrieval even when the browser is offline. Combined with online/offline events, developers can write JavaScript that acts intelligently until the connection is restored. This preference determines whether the offline cache is enabled.

I create a setting, but I think it is not easy to reason why this is a risk or not. I add this, because it possibly is kind of another type of cookie. I am not 100% sure, but I guess storing unique content can be used later for identifying the user.

Something to explain the risk to users would still be nice.
