The main reason given for using DDG are privacy concerns with Google. Therefore sending every query to DDG's servers doesn't make sense to me. The redirect will be slower too than searching directly through your browser.

On the configuration side, that doesn't make sense either.

You configure it once and then because of Sync you get those configurations wherever you're using Firefox. And in Firefox at least it is easy - you just right click on a search input and select "Add Keyword for this Search". It's much, much faster than searching for the right bang in DDG, as those bangs aren't exactly obvious. And I only care about a couple of websites, less than a dozen, instead of hundreds.
