Open-source browser Firefox has a new version and a new anti-cryptojacking feature. This was revealed in Mozilla’s latest blog.
The company mentioned in a previous blog post how websites can set up scripts that would release a crypto miner on someone’s device without them knowing. This is known as cryptojacking.
Mozilla’s Collaboration with Disconnect
Mozilla has taken steps to fight back against this practice. The company has collaborated with online privacy firm Disconnect to develop a crypto mining blocker for Firefox. Users can opt-in its latest feature and toggle it to block potential cryptojackers from utilizing the device’s reserve computing power to mine digital currencies.
Mozilla first revealed its plans to stop cryptojacking last year. The company had integrated cryptojacking features on its Nightly 68 and Beta 67 browser versions, just before Firefox’s latest iteration, Quantum, was launched.
Quantum also wants to reduce incidents of “fingerprinting,” which creates a copy of a user’s digital fingerprint and utilizes it to monitor their internet activities.
Cryptojacking at consumer levels was said to be basically extinct by cybersecurity firm MalwareBytes in April. According to the company’s report, “consumer cryptomining seems to have gone the way of the dodo.” This was reportedly due to the operations of mining business CoinHive being shut down. After that, activities of bitcoin miners targeting consumers were said to have dropped from 2018. However, the number of business-centered miners have allegedly increased from last quarter, particularly in the APAC region.
It was also reported that exposures of consumer malware have been reduced to around 40%. Unfortunately, cryptojackers remain focused on businesses.
