Malwarebytes: Chrome and Firefox extensions hijack browsers and block users from removing them. The extensions are designed to keep users from landing on sites designed solely for that purpose. The Chrome extension is a one-of-a-kind so far, says Pieter Arntz, malware intelligence researcher at Malwarebyte. Firefox extensions are being pushed by cryptocurency websites that reward visitors with free content or other incentives for completing tasks like watching ads or completing captchasions. Chrome users have an easier time escaping such sites, by simply opening a new tab and then shutting down the offending tab.”]
