 Looks like we can easily hack this similar to how we hacked the
 permissions manager to be memory only. SiteZoom, along with an unknown
 additional set of 'content' preferences, is stored in a database
 connection via toolkit/components/contentprefs/nsContentPrefService.js.
 The database connection is created in _dbInit().


 We can also clear some (but perhaps not all?) items from the content-prefs
 database via removeGroupedPrefs():


 That function should clear the site zoom at least.
