If you know something about it then this code will block iframe in FF:

iframe
{ display: none; }

Thank you.

Hmmm ... I've always wonderd about that "display:none": Does it just
suppress *displaying* the element, or does it actually fully ignore the
element ? I still do not know.

(Good question.)

But there is a small problem with such a solution: its an all-or-nothing
one, where I would like to be able to remove *selected* iframes. For

Agreed: I found, when I had IFRAMEs disabled, that parts of some
webpages didn't work - but in ways that weren't obvious: there was
something that just didn't show, but with no obvious indication that
something was missing. (I think examples included parts of "Verified by
Visa", and some Captchas.)
