Here are the filters I have been using in K-Meleon 74, 75, and all Goanna versions, effectly blocking all inline adds.

Plase bear in my mind that exclusion filters here actually needed here to compensate my other/general blocking filters, you may not need those.
Also, all ABP filters are scattered, but there is a very little chance that I missed anyone.
Thanks

How do I add these in Goanna?
