This is malicious code from Opera, it is intentional. Once you use the Opera Google search engine with a Chinese network IP, it will disappear.
This is very bad for us opera who travel to China.

I used China Wi-Fi while traveling in China, and the opera google search engine disappeared.

@leocg I don't want to reinstall Opera
Please delete the malicious scripts in your Opera default search engine settings.

Or allow users to "customize the default search engine URL" new function

I traveled to China once Browser search engine is default to Baidu, I can't find Google search engine in opera settings>search engine What should I do?
When I went back to the US, my browser search engine still default to Baidu.
Now every time I search for something, I have to visit google.com first and then type in what I need to search for, it's a pain in the ass.

no google search engine
