Does what it says, and if ti doesn't work it gives you ways to report sites with issues. Developer is active and responsive. Don't pay any attention to the 1 stars here. People who want someone else to "fix" these issues but don't want to pay anything for others work don't get a say as far as I am concerned. You either donate or put up with the clicking on all the "I agree" buttons on 70% of websites now a days.
