The popular web browser Firefox will automatically block the malicious scripts associated with the hidden mining of cryptocurrencies, in the framework of a broader program to improve the quality of the product.

Nonprofit organization Mozilla Foundation announced that it intends to add blocking the “malicious practices” in the next releases of its browser. The ultimate goal is to prevent quality drop using the browser as a result of actions of third-party scripts, Vice President of product Mozilla Nick Nguyen. Such scripts are usually embedded in web sites, and manage computer resources without the user’s knowledge.

This category includes scripts that use the custom computing power for mining cryptocurrency.

“Deceptive practices that allow you to discreetly gather user credentials or harm the user experience, become ubiquitous,” writes Nguyen. “For example, some trackers do the user – a method that allows them the invisible way to identify users by characteristics of their devices. Users are not able to control it. Other sites set crypto-mining scripts that covertly mine cryptocurrency on the users ‘ devices. Like these practices make the Internet more user-hostile. In future versions of Firefox we will block them by default.”

New functionality will be tested in Firefox Nightly. If all goes well, the hidden blockers miners and other malicious scripts will be enabled by default in Firefox 63.

Previously, certain attempts to protect users from hidden miners were taken 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 its SOFTWARE. By the time a similar functionality was already built into the desktop version of Opera.

Google, in turn, was forbidden to publish apps that are capable of mining cryptocurrencies, in the Play Store. Regarding the locks of malicious scripts on web pages, the company is no ad did.
