ABE LOCAL rule and GetForecastFox extension

I use great weather forecast FF extension Getforecastfox, based on AccuWeather data.
Configuration of extension is done by invoking page on http://www.getforecastfox.com, JS required.

When I enabled SYSTEM LOCAL ABE rule, it stopped working, until I weakened LOCAL rule to allow access from www.getforecastfox.com.

Currently I use the following code, but as I am newbie to ABE and HTTP internal things,
I would like if revised a/o adviced better settings.

# Prevent Internet sites from requesting LAN resources.
Site LOCAL
Accept from LOCAL
Deny INC
Accept GET from www.getforecastfox.com
Deny

I used Deny INC, as I was afraid Accept GET may cover some activities denied by Deny INC
