I'm surprised that you're unfamiliar with such a long-established competing product. I provided a link to the BlueHarvest main page above, in lieu of copy-and-pasting a bunch of its explanatory content into this post. Perhaps you could take a moment to click that link and check it out? I would think that any differences would stand out to you immediately.

@jdmc my apologies It uses Safari’s native content blocking APIs. So it doesn’t really works like any of those other extensions you mentioned.(as far as I’m aware anyhow) It’s very much intended for users who know what they’re doing, as it can be quite unforgiving.
