LnS with Firefox

I'd like to use firefox with Look n Stop, but the available rule allows both inbound and outbound traffic. Is it possible to only use an outbound rule for http traffic? What can I do to create a functional rule that will allow http outbound, but does not blobk http responses?

I'm not sure what else the http in/out rule might allow in via http. I need to be as close to certain as I can get that only the requested http traffic is allowed back in.
If anyone ha a rule that works as http outbound (not http in/out), please explain or post.
I have tried adjusting loopback, but not sure if I did that right.

Help

Would someone help with the question above?

There is not specific rule for allowing outbound application like Firefox.

The only thing you need to check that this software is listed in the Application Filtering page and that it is authorized.

'Application Filtering' tab if mainly to filter application to access the internet
