Getting a new computer set up and my Kapersky AV runs an ad blocker.
Is there a single url that I can enter into the exceptions list that will allow ads to visibly run on all sections of PFF?

not sure how Kapersky works, but it probably has to have an add in for whatever browser you are using. I am using "AdBlocker Plus" in Firefox. When you are on a page, you can click the icon for AdBlocker in the tool bar, and it has opetions, like, Block all adds on this page, never block ads on this page, allow adds this visit.... ect....

I sometimes use Windows 'Edge' which is W10 browser and sometimes use Chrome browser. With Kapersky, it provides the firewall for both, so I need to make allowances for PFF ads within Kapersky.

Just out of curiosity....you are trying to ALLOW ads to run? Most people try to block the annoying ads on websites.

I only want them to load on selected websites..PFF being one of them.

Allowing ads won't help unless you also allow Flash to run. I do not allow flash to run unsupervised on my computer. Mainly to stop those annoying autoplay videos, but flash is also full of security risks as well.
