@leocg if you enter a URL like "http://127.0.0.1:8188/" in another browser then hit enter, it goes to that web address.
As it should.
I suspect the issue is that there is some buggy invalid URL detection code going on with OperaGX and hence its sending it to the search engine instead of loading the URL.
@BJlag In sync.opera.com the passwords will always be encrypted. You need to login to Sync in the browser to get your synced passwords into your password manager.
