Keep in mind that it blocks *trackers*, not *ads*. The main advantage it has over, say, Privacy Badger and newer browser settings is that it detects email address fields and offers to generate a disposable alias (if you use that feature)

All the ad on's I try to download it says the files are corrupt.

Seems like it's working. However, I'm not sure why, but it seems that when adding DuckDuckGo Security & Tracker Protection, it's actually trying to add DuckDuckGo Privacy Essentials. The fire button is missing and I've went through several troubleshooting steps to get the full version. It seems like there's an error with how this full version is packaged. I can't get the fire button to appear.
