If you ever try to use the Adsense refferals like Firefox. The freaking button sometimes don't appear and just leaves a blank space. What is the point of this? Its hard enough to get people to click on them and download it, let only having the button only show up when it feels like it
Meh.. I've noticed this as well. My favorite though was when the referral button's text changed to Korean for two-to-three days.
Adsense referrals have been having issues over the last few weeks, I've noticed. However, historically, it's not that unusual for one or more buttons (Firefox, Adwords, Pack, etc.) to just simply disappear for a few days when Google Has Issues. They come back. Eventually. Usually after I'm ready to pull my hair out. If you have older code saved somewhere, sometimes the older ad styles will display when the new ones don't, and text ads almost always display. For me, the current problem resolved on Monday. -- Leva
