|
|
* @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
|
