I decided to try changing my Ad Blocker due to an annoying, verging on about to become full-blown PO'd, glitch with Facebook: The other ad blocker couldn't quite keep FB from inserting ads until after they'd already interrupted the scrolling through and/or viewing of [an] entry(ies), thereby making the entries jump and chop. It was awful! 'Ultimate' has stopped this problem cold; first try! We are VERY pleased. If it continues so, we will probably contribute. Cautious thanks!
