It seems some time in the past week, maybe since Friday, ABP stopped working using Google Chrome. It no longer blocks those ads in videos, nor even regular ads that appear on webpages. In fact, you can select to block something, but it doesn't let you click the option to add the rule.
I found plenty of search results of ABP not working in Chrome, going back years, and I'm not sure if it is related or not. Has anyone else had this problem recently or before?
