Firefox does not send out any security warning messages, it's a browser only. Do not click or answer any of this kinds of pop-ups, if you do, it'll install virus/spywares into your PC. Just ignore them.

Please read this article and follow cor-el suggestions to scan your PC with those anti-virus/spywares programs to make sure your PC hasn't been infected.
