A while back, I started a master list of Safari content blockers (at least the ones I found). Over the weekend, Carlos Oliveira and I banged around a few ideas and Carlos edited the list, adding 2 codes to each entry.

One code indicates whether a content blocker is free, the second code indicates whether the content blocker supports an editable white list (turn off blocking for specific sites).

Please take a look at the list, ping me if you spot any errors or missing blockers. The link remains the same.
