Opera web browser announced on January 22 that it launches protection against cryptocurrency mining scripts to its mobile browsers. Opera has already introduced the feature to its desktop products called NoCoin.
The new anti-cryptocurrency mining 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.
According to the company, more than a billion people worldwide is estimated to be affecting hidden cryptocurrency mining scripts, causing their devices to run warm, become slower and eat up their batteries.
When you browse the web, there are no visual clues that your device is exposed to mining. 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.

After several tests of the Opera browsers for smartphones performed on Samsung Galaxy S8 and HTC One, developers at Opera determined that scripts mining for cryptocurrencies can increase the smartphones’ CPU usage up to 100%. This can cause increased battery draining and make the phone overheat.
According to the company, Opera's new feature is already available, and the browser can be downloaded from the Google Play or the App Store.
