Opera recently became the first major browser to add protection against cryptocurrency mining scripts to its desktop products. Now, Opera launches the feature in all its mobile browsers, protecting hundreds of millions of smartphone browser users.
Cryptocurrencies, like Bitcoin, have become a hot topic and, with their surge in value, so has the mining for new coins, known as cryptocurrency mining. While some use their own data centers, many web developers are increasingly using people’s computers and smartphones for this - often without their consent. The phenomenon is estimated to be affecting more than a billion people worldwide, causing their devices to run warm, become slower and eat up their batteries.
According to some reports, there are currently more than 3 million websites exposed to cryptojacking, so the need for extra protection is bigger than ever. 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.

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.
