Leading web browser Opera has rolled out cryptocurrency mining protection in all its mobile browsers.

Earlier this month, Opera announced a new browser ‘Opera 50,’ which comes with an innovative anti-Bitcoin mining tool, extended VR360 support for Oculus, and Chromecast, among other features. The anti-bitcoin mining feature protects users against web developers who use people’s computers and smartphones for mining purposes – often without their consent.

“When you browse the web, there are no visual clues that your device is exposed to mining,” says Jan Standal, VP Product Marketing at Opera “A single webpage you visit can take up to 4.5 hours of your battery time, if you keep the tab open. This often turns out to be just the battery time you needed to use a ride-hailing app or check the map to get home”.

According to the official release, the new feature is activated by default when enabling the ad blocker on Opera Mini and Opera for Android. The ad blocker can be enabled in “Settings”, and it will automatically detect and stop the mining scripts written into the coding of a webpage.

“By blocking mining scripts, Opera ensures that its users’ smartphones continue to run smoothly and that they have enough battery life for the things they really want or need to be doing,” Opera said.

Furthermore, Opera has also created a website which will help users to check if their browser is affected by unwanted crypto mining – www.cryptojackingtest.com.
