Re: Google Drops Instant Previews
I'd really guess that the FireFox ad-on is only going to display rudimentary HTML content. One simple thing to look for is whether banner ads are visible in the preview at all. If they are, then some Flash content is being rendered, and there's a possibility of (a possibility of) an attack vector. It seems very unlikely to me, however.
Sad that previews are going away, though; I rather liked them.
I know I shouldn't use tildes for decoration, but they always make me feel at home~
