I"m very frustrated with the search engine choice we have in Opera. It's impossible to delete the default search engines like Yahoo, Amazon, etc. I don't want these in my browser, but I can't delete them.
To make things worse, there is a keyword to trigger these engines. If I begin my research with "z", it will redirect me to Amazon. That's very frustrating. Please allow us to configurate this, and to delete it.
What I am talking about : https://ibb.co/1qzV31D . I want to remove these engines (excepted google, duckduckgo).
