Mozilla Firefox will soon block crypto mining malware automatically
Mozilla Firefox, an open-source web browser, said that it will soon start blocking crypto mining malware scripts, in a move to enhance its performance. The Mozilla Foundation, the non-profit organization behind the browser, said it plans to block trackers and other harmful practices in its upcoming releases.
In a blog post by Nick Nguyen, VP Firefox Product at Mozilla, he talked about how websites deploy cryptomining scripts which silently mine cryptocurrencies on the user’s device.
Basically, this refers to scripts from external parties that hijack a person’s unused computer power to mine cryptocurrencies. In the coming months, new versions of Firefox will block this practice automatically.
“In the near future, Firefox will — by default — protect users by blocking tracking while also offering a clear set of controls to give our users more choice over what information they share with sites,” he wrote in the post.
“Deceptive practices that invisibly collect identifiable user information or degrade user experience are becoming more common,” he added.
Other features to be rolled out
Besides blocking such harmful practices, Firefox will also focus on improving page performance. A new feature has already been added in Firefox Nightly to blocks trackers that slow down page loads.
Additionally, the web browser will strip cookies and block storage access from external tracking content. This feature is available for Firefox Nightly users for testing. The team will run a shield study for beta users to test in September.
“Some sites will continue to want user data in exchange for content, but now they will have to ask for it, a positive change for people who up until now had no idea of the value exchange they were asked to make,” Nguyen highlighted.
Firefox joins other browsers in fight against malicious miners
Firefox is not the first web browser to offer its users protection from cryptominers.
Earlier this year, Opera had introduced a default crypto miner protection to the smartphone version of its browser. The browser already has cryptominer protection on its desktop version.
In July, internet giant Google had banned applications that allowed mining cryptocurrencies on mobile devices. However, it recently came to light that some of these banned applications were still present on the Play Store, as reported by Next Web.
