Just put !mdn in your DDG search and it will take you right to MDN. Same with !g for Google, !w for Wikipedia, etc.

In Firefox, right-click the search box at developer.mozilla.org and select "Add a Keyword for this search". Put a keyword, something like m.

Then you don't even need a search engine. Just type

  m your search term here

in the URL bar to search the site directly.

Wow! That's wicked cool- thanks for the tip!

EDIT: I'll add for others that this keyword is stored as a bookmark, so you can find it in your bookmarks and edit/delete/etc.

!mdn uses mdn's search and returns their results, but I actually prefer ddg's. And using only mdn has the side-benefit of including relevant SO results (and others) lower on the front page sometimes.
