Well, this sounds like mumbo jumbo to me and if it's such a problem then it should be changed. Yes I have enabled it and so far I didn't see any problems. Thanks, so this option still exists! But there is a problem, I still can't figure out how to allow embedded stuff from Instagram and Twitter on certain sites, because those scripts aren't even listed in uBlock's GUI. So Ghostery is a better solution for me at the moment, at least on certain sites.
