Cookie warnings (I think coming from EU directives) are becoming more common and more annoying. Cookies are not blocked in Safari (12.1.2) preferences. AdBockPlus (2.06) is also installed, which does a good job of suppressing unwanted ads. The iMac is running 12.14.6, and I'm located in the US.
A little searching indicates I might enable Prebake to suppress these warnings. The Prebake page contains a link to add Prebake's filter list to the Safari filter list, but Safari won't load the linked page, not surprising given the link's formatting. Deleting the characters before "https" doesn't help. Neither Safari preferences, the ABP icon in Safari, nor the ABP Control Panel (2.0.6) show or suggest how to access the Safari filter list.
I'm not a programmer, but only a dilletante amateur. Is there a way to add this filter to the Safari filter list? Alternatively, is there another way to suppress these repeated cookie warnings?
