I would recommend enabling Chrome extensions: https://addons.opera.com/en/extensions/details/install-chrome-extensions/ Then getting my extension from the Chrome store: https://chrome.google.com/webstore/detail/new-tab-start-page/mjfahldkpjhcnfbbmdhpjolcjpcfhcpj I had one published in Opera store but as mentioned above, it was removed. I even tried publishing a version that doesn't change the new tab page, but I didn't even get a response about it being reviewed or anything. Opera extension publishing has become a nightmare ...
