Greetings Chordians! We had another thread awhile back addressing this (problem?) further down the section. The culprits are Google Adsense, Google Analytics, and Quantcast..... not a Chordie issue, but easily overcome by adding the Ad Block Plus plugin to your browser. I use it and Ghostery, as well as deleting cookies on closing the browser. No ads no pop-ups and everything displays just as intended.
Some members are using different add ons that get the same end result, so you might want to scroll down the About Chordie section and scan the posts from earlier.
BJ; Your comment about Netflix may have some weight, if you commonly watch Hulu or other streaming entertainment that is ad supported, you have to "allow ad-blocking exceptions" for that site (and you can specify, so it just doesn't turn it off for everybody). That's how they support the service and without allowing the ads, you don't get to have the content.
Keep us posted & be safe out there;
Doug
