OK I saw it FF with and without JS. I think it's OK to sue noscript that way. FWIW.

 

You really really have to fix your markup and css, you have a really bad page in IE7. No idea how you happen to see it OK. Are you using IE8 with compatibility or whatever it's called? Obviously it's not the same as true IE7.

 

In IE7 I am also not seeing any of your Adsense ads.

 

I am not aware of blocking anything except a few trashy sites - and they are blocked in the hosts file so regardless of browser they'd be blocked.
