Advanced user? Experiment with Opera developerThis is the earliest experimental rollout of our browser innovations, and not all of the experiments will move on to the next stages. Please note because the new features in Opera developer are so raw, they can be unstable and even crash your browser. Test with caution! This is the version for you only if you’re a developer, advanced user or enjoy living on the edge.
