This extension used to be really useful, but unfortunately it doesn't seem to work anymore.

For anyone looking for an alternative, I ended up creating DuckDuckGo Custom Tabs, which provides the same core functionality and adds a few extra features.
Hopefully it can be useful to others as well.

Great extention, but it does not work anymore. This may be caused by the new antimonopoly regulation in the European Union, where I live. Hopefully it can be fixed easily. Thank you!

Surprisingly still works well

Something good made perfect!

It works very well. The default Apple maps was the one thing that annoyed me about duckduckgo. This is the Duck's best kept secret.

Works great!
Now, I can use Google Maps inside of DuckDuckGo without their gawd awful Apple Maps (unreliable). Don't expect an icon for it on the top right corner of FireFox, like other add-ons. It will show up as an option in DuckDuckGo results tab, like All, Images, Video, and "GoogleMaps" will be there. The one-star rating from another reviewer is just user-error.

Perfect if you want to keep using Google maps instead of Apple's one

Muy buena, por defecto DuckDuckGo utiliza Apple Maps, con esta extensión podemos tener la pestaña de Google Maps u OpenStreetMap en el buscador

Very handy. Thank you.
