Can't Sign Up Google AdSense with Firefox 3.x

Have we ever getting problem with firefox 3.x When we try to sign up google adsense and we click sign up button we'll get a half blank page that has just a few links that included this forum?
Is the site broken or what's happening?
In other word we can't sign up for Google Adsense and Pages are blank when we use firefox 3.0.x browser. This will only happen if we use Firefox with AdBlock Plus (ABP) Add on/Extension.
To solve the problem try to disabled / reconfigured ABP, so we will good to go. Hope this helps you all.
(I found this problem solved from Google AdSense Help Discussion)
