If you get a pop-up message asking to update Firefox or plugins or scanning for malware then such a message is likely a scam and you should never respond to such an alert to avoid getting infected with malware.

• Only update Firefox via "Help > About" or by downloading and installing Firefox from the Mozilla server and never via a pop-up or link on a web page.
• plugins should only be updated via the plugin itself or by visiting the home page of the plugin.

Message appearing to be a Firefox page saying I needed to do a update to a allow a firewall port exception. It appeared it came from noakodeathvalleydriver.org https:noakde.........192457d548html

Another thread states it was about a fake firefox-patch.js file. Unless they changed some wording the Fake page is normally with words of urgent Firefox update.

Mozilla has no need to host Firefox stuff outside of a *.mozilla.org page.
