Firefox, a popular web browser, is about to automatically block malicious scripts, designed for cryptocurrencymining.
Last Thursday, the nonprofit organization Mozilla Foundation announced, that upcoming Firefox releases would contain the lock of "malicious practices". Some of these functions, such as anti-tracking, are now available in beta version of Firefox Nightly.
According to Nick Nguyen, Vice-President for Mozilla products, the company aims to maintain the quality of browser usage by blocking third-party scripts. Such scripts are usually embedded in web sites for further control of the machine's computing power without the user's knowledge. This category also includes scripts, that use computer resources for mining cryptocurrencies.
"These practices, which enable covert collection of user credentials, are becoming more common. For example, some trackers take users' fingerprints, enabling quiet users' identification by their devices' characteristics. Meanwhile the users themselves can't control these actions. Other sites use scripts for mining of cryptocurrencies, which operate on users' computers without their knowledge. These practices make the Internet an increasingly hostile place, so in future versions of Firefox we will block them by default."
In order to test new functions Firefox Nightly version will be used. In case of successful tests passage the minerslock feature will be added and enabled by default in Firefox 63.
Mozilla has teamed up with the developers of other browsers, including Opera and Google, in an attempt to protect users from malicious miners, that are slowing down computers' operation or even damaging them.
This year's January, the Opera developers announced the creation of the shield against miners for the mobile version of their browser, that will be enabled by default. At that time, the cryptomining blocker was already built into the desktop version of Opera.
Google, for its part, banned all the cryptomining apps for Play Store. However, the company hasn't yet made any official statements, concerning the automatic blocking of scripts on web pages.
