Can't edit search engine in Opera browser mobile
I long press a search engine but I can't find an option to edit the engine. Version 19.
you can't edit built-in search engines.
you can add custom search engines by long-pressing the text-entry box of a compatible search engine, and you can delete them by sliding the entry in the search engine list to the right.
renaming search engines or changing their address is not possible.
That sucks. With old Opera Mobile, I was able to remove those engines.
