42 * Import permissions from perferences to the Permissions Manager. After being

44 * Perferences are only processed once during the application's
45 * lifetime - it's safe to call this multiple times without worrying about
46 * doing unnecessary work, as the preferences branch will only be processed
47 * the first time.
48 *
49 * @param aPrefBranch Preferences branch to import from. The preferences
50 * under this branch can specify whitelist (ALLOW_ACTION)
51 * or blacklist (DENY_ACTION) additions using perference
52 * names of the form:
53 * * <BRANCH>.whitelist.add.<ID>
54 * * <BRANCH>.blacklist.add.<ID>
55 * Where <ID> can be any valid preference name.
56 * The value is expected to be a comma separated list of
57 * host named. eg:
58 * * something.example.com
59 * * foo.exmaple.com,bar.example.com
60 *
61 * @param aPermission Permission name to be passsed to the Permissions
62 * Manager.
