Ah, my apologies for going off-topic. Wasn't my intention. Will check out AdGuard, thanks.Does "in the old days" mean before Apple nerfed Safari extensions? If so, Adguard is the best ad blocker I've used on the Mac by leaps and bounds. It runs as a kext and can block ads system wide. It also blocks at the DNS level for some of the tricker stuff, which also saves bandwidth since your computer will terminate connections to known ad domains at the earliest stages of a web request.
This is getting off-topic, however.
