Opera is now also in the mobile browser against the unwanted and hidden crypto mining without the consent of the user. With Opera 50, the company has already extended the desktop browser in early January 2018 with a NoCoin feature to suppress hidden mining.
When the company announced NoCoin for the desktop that around 500 million users unconsciously calculate cryptocurrency in this way for other users in the background, it now speaks of more than one billion affected users, because of the recent huge gains more and more Websites would rely on this technique. Around three million websites are currently set to “crypto jacking”, as the name for the hidden crypto mining in the background without the knowledge of the user. Especially with smartphone users, the effects are even more noticeable, because the smartphones are very hot by calculating and the battery life decreases sharply.
The NoCoin technology, which was already introduced on the desktop, has now been introduced by Opera for the mobile browser Opera Mini and Opera for Android. Again, the anti-crypto jacking technique is linked to the activation of the ad blocker of the mobile browser – as in Opera 50 for the desktop. The anti-mining feature is also activated by activating the ad blocker. However, unlike in the browser, it can not be used separately due to lack of setting options if the user deactivates the ad-blocker, but still wants to use the anti-mining function – it can only, at least under Android, as a self-experiment by ComputerBase showed Both are used simultaneously.
When you browse the web, there are no visual clues that your device is exposed to mining. A single webpage you can take up to 4.5 hours of your battery time if you keep the tab open. This often turns out to be the time you needed to use a ride-hailing app or check the map to get home.
