Suggestion of adding search engine baidu.com
@neilfan If Vivaldi would receive money for doing this is the only way they would even consider it. They have financial arrangements with all default search engines.
However, if they were to do it, I would immediately delete it. I would not have it on my machine if you paid ME. That said, if you would like to have such spyware on your machine, you are free to add it to your list of search engines. Just go to the site, right-click in the search box, and select "add search engine" from the context menu. But don't blame me when your every move and half of your personal data is phoned home.
