Based on Chromium 63.0.3239.108, Opera 50 appears to be the only major web browser that promised to protect your computer against Bitcoin mining. Dubbed NoCoin, the anti-Bitcoin mining protection has been implemented in Opera’s integrated ad blocker, which can be easily enabled in Settings under the Recommended lists of ad filters of the Block ads option. Besides the cryptocurrency mining protection feature, Opera 50 ships with Chromecast playback support to allow users to stream their favorite content from the web browser to a big screen TV, support for the Oculus Rift VR headset for the built-in VR (Virtual Reality) player, along with software decoding and automatic format detection.
