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.

Yes, it's a scam. "Call this number now" belongs on the shopping network only.

If you want to make sure you're safe, follow these instructions: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware#w_how-do-i-get-rid-of-malware.
