Maybe you installed adblock plus?

 

Or maybe you has just added the code to the page.

Anyway, the 2 ad units at the top are not looking good BTW.

 

google ads takes some time to show on site's after getting the code, so wait for some time...

 

Maybe you should clear your FF cache?

 

The ads show in my FireFox fine. I would suggest changing the block types and positions though.

 

Ads appear fine to me aswell.

 

Maybe You install the ads blocker in your FF.

 

Maybe your firefox is blocking Javascripts.

Go to Settings and "Allow" Javascript.
