Hi All, Newbie here, please can someone tell me what to do to enable duckduckgo to work in the address bar. every time I type anything (That is not a genuine URL) it pops up with a box to download ac.json. What I am I supposed to do with it please?
Go to https://duckduckgo.com/ and right click the search field. Select "add as search engine". Then go to vivaldi://settings/search/ and set it as default by clicking the checkmark.
Alternatively you can visit vivaldi://settings/search/ and click "reset to default". This will delete all your custom search engines, but as far as I know duckduckgo is added by default already, then you just have to set it as default anew.
Thanks for your reply. I already did what you suggested and duckduckgo works fine in a separate tab or in the side bar. The problem only occurs when I try to type a search into the address bar.
I have no idea what ac.json is, but it doesn't sound like this is bundled with Vivaldi. You might have some third party code on your install doing this. Try a reset -->

ac.json isn't something foreign. It's what is sent to the browser when it tries to load search suggestions.
example, typing "something" in the address bar loads the auto-complete suggestions from https://ac.duckduckgo.com/ac/?q=something as a json file
Normally, vivaldi should interpret this and show search suggestions from the autocompletion list, but this seems to have bugged somehow.

That's weird, search suggestions via duckduckgo are working for me.
edit your duckduckgo search definitions and see if you have
in the second field, for suggestions.
@LonM Damn, you're obviously right. But I still wonder why a request for download pops up, it doesn't really make sense.
I have Vivaldi 1.11 and use DuckDuckGo without problems from the address bar
What extensions do you use?

If you are working JSON data I would suggest using JSON Formatter tool for formatting and Validating JSON data.
Thanks for all suggestions.
iAN CooG - that's exactly what I have defined under the search choice in Settings.
Catweazle - only extention is uBlock Origin.
jamesmalvi - not using (Or don't believe I'm using) JSON data
