Folks, it's not ABP. ABP is blocking a rogue extension from communicating with superfish.com - and you're seeing the text alternative.
Try this... Go here: http://www.speedtest.../3636793458.png
This is a benign image of a speed test. If you have the superfish code, you'll see its text just beneath the image (make sure ABP is on).
Leave that page up. Then bring up another page with your extensions (chrome://extensions). Turn off ALL of them EXCEPT ABP. Then refresh the image page above. If the text is gone, start turning on one extension at a time - refreshing the image link between each activation. When you get to the culprit, the text will reappear beneath the image. Then just leave that extension off (or remove it).
Seems like a lot of Chrome extension developers are "selling out" to ad companies. I'm reading they're paying 6-figures PER MONTH to buy rights to add their code to existing extensions. Since Google has cracked down on getting new extensions approved, they've resorted to corrupting existing ones.
If you find which extension is the evil-doer, please post it here.
