* Normally the preferences are set using Services.prefs, but this actor allows
* a debugger client to set preferences on the debuggee. This is particularly useful
* when remote debugging, and the preferences should persist to the remote target
* and not to the client. If used for a local target, it effectively behaves the same
* as using Services.prefs.
*
* This actor is used as a global-scoped actor, targeting the entire browser, not an
* individual tab.
