That is another kind of scam, on this on the vulnerability is Chrome Browser... I just take a look to the addon source code and as you mentioned, it's some malware who get our personal info, tagged sites are:
"matches": [
"*://*.yandex.ru/*",
"*://localbitcoins.com/*",
"*://*.yahoo.com/*",
"*://*.hbg.com/*",
"*://*.huobi.com/*",
"*://*.blockchain.com/*",
"*://*.okex.com/*",
"*://*.live.com/*",
"*://*.google.com/*",
"*://mail.ru/*",
"*://*.binance.com/*",
"*://*.coinbase.com/*",
"*://*.qq.com/*",
"*://*.mail.ru/*"
]
So, the best option is to stay away from it. I will add the site to the list. Thanks.
