The (Firefox only) solution (http://blogs.zdnet.com/security/?p=1973)

Sounds pretty scary, but I applied the NoScript preference.

Looks like the best way to prevent it is just to use Links or Lynx :D

The problem affects all of the different browsers except something like lynx.

Anything that doesn't parse iframes should do.

That article was linked from slashdot too yesterday. The article just says there exists an exploit but doesnt tell what it is. I still don't get how this 'clickjackin' works! They probably haven't disclosed it for security reasons but how do I protect myself if I dont know wht the trick is?

It uses a hidden iframe to trick you into continuously clicking on a link of some kind. If an attacker can predict where you will click, then he can probably get you to click there. Sounds a bit like an early Firefox bug where if an attacker could predict or create a download or addons box they could install it by getting the user to click somewhere repeatedly.

I can only see disabling hidden iframes as an option. Seriously, what is the advantage. I mean, hidden links in a hidden iframe. I cannot see that being useful to anyone but an attacker.

I forbid iframes in general w/NoScript.
This way I can allow them if I trust the site.
