FF - Fix updates from the exclusions popup

This stops |Exclusions| from holding a reference to the |value|
parameter passed to |Settings.set|. In Firefox, this object is garbage
collected when the owning context (the exclusions popup) is closed.

The fix for all such cases in the future is to switch to using
|Settings.get|, which implicitly does |JSON.parse JSON.stringify value|
and thus returns an object in the same context as |Settings|.

We could fix this generally by doing this for the
|Settings.performPostUpdateHook| call in |Settings.set| instead.
However, I'm not convinced that it warrants the overhead of a
|JSON.parse| for every |Settings.set| call.
