Disable displaying the search query in address bar.
How to turn off displaying of the search query from the history in the address bar to be I could see only the entered address?
Open settings. Choose "Search" tab. There's option for "Allow Search suggestions in" address field.
This options disabled, and does not work for this. I'm testing this before and try alse one now.
Aah, yes I miss your keyword "search query from the history in the address bar". Triple checking checking your picture; it was "Typed" in Eng Vivaldi. Sorry for my miss flag.
Sorry for my English
There don't seem to be a way for disabling it the way you want, so please add your feature request to the list here. Just keep in mind that Vivaldi developers have more important things to deal with atm, but I'm sure they won't ignore your request and they may add such feature at some point. Until then, you can just keep coming back here and post your request again, each time a new version of the browser rolls out and a new feature requests thread starts.
In the meantime, you can also take a look at a possible workaround for this, that I described here.
