Comodo Online AV scanner problem!

Hello!

I tried to use comodo av scanner online under firefox (latest). Added the FF addon, but, I can’t use av scanner.
Error message: Comodo AV Scanner control is not
available on a restricted web page.
Error code: 0020

What is this error? How can I use av scanner.

And my second problem: the Comodo own browser, the Dragon why don’t supported?

Thanks!

that is really old, don’t bother using it right now. It needs an update badly.
