Firefox will start blocking scripts for hidden cryptocurrency mining
Popular Firefox web browser will automatically block malicious scripts associated with hidden cryptocurrency mining as part of a larger product quality improvement program.
The Mozilla Foundation, a non-profit organization, has announced that it intends to add blocking “malicious practices” in upcoming releases of its browser. The ultimate goal is to prevent a drop in browser experience from third-party scripts, said Nick Nguyen, vice president of product for Mozilla. Such scripts are usually embedded in websites and manipulate computer resources without the user’s knowledge..
This category also includes scripts that use custom computing power to mine cryptocurrencies. “Misleading practices that allow users to subtly collect user identities or harm user experiences are becoming ubiquitous,” Nguyen writes. “For example, some trackers take a snapshot of a user, a technique that allows them to invisibly identify users by the characteristics of their devices. Users are unable to control this. Other sites install crypto-mining scripts that secretly mine cryptocurrencies on users’ devices. Practices like these make the Internet more hostile to the user. In future versions of Firefox we will block them by default. “.
The new functionality will be tested in Firefox Nightly. If everything goes well, then blockers for hidden miners and other malicious scripts will be activated by default in Firefox 63.
Previously, certain attempts to protect users from hidden miners were made by Opera and Google.
The developers of the Opera browser in January announced the creation of a safety mechanism for users of the mobile version of their software. By that time, similar functionality was already built into the desktop version of the Opera browser..
Google, in turn, has banned the publication of applications that support the ability to mine cryptocurrencies in the Play Store. The company has not made any announcements regarding blocking malicious scripts on web pages..
