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

* imported, all processed permissions will be set to an empty string.
|
|
* Perferences are only processed once during the application's
|
|
* lifetime - it's safe to call this multiple times without worrying about
|
|
* doing unnecessary work, as the preferences branch will only be processed
|
|
* the first time.
|
|
*
|
|
* @param aPrefBranch Preferences branch to import from. The preferences
|
|
* under this branch can specify whitelist (ALLOW_ACTION)
|
|
* or blacklist (DENY_ACTION) additions using perference
|
|
* names of the form:
|
|
* * <BRANCH>.whitelist.add.<ID>
|
|
* * <BRANCH>.blacklist.add.<ID>
|
|
* Where <ID> can be any valid preference name.
|
|
* The value is expected to be a comma separated list of
|
|
* host named. eg:
|
|
* * something.example.com
|
|
* * foo.exmaple.com,bar.example.com
|
|
*
|
|
* @param aPermission Permission name to be passsed to the Permissions
|
|
* Manager.
