I like the ddg bangs too but I’m weaning myself off them, instead using keywords in Firefox. It’s really easy: just right-click (ctrl-click on Mac?) on a search field then select “Add keyword for this search”.

Especially since they started removing (censoring…?) bangs for the likes of Sci-Hub and torrent sites, and since I got thinking that perhaps they don’t need to know a history of all my searches on all the websites.
