Thanks for the insight, Foxtail Rated 1 out of 5 stars

The Google Disconnect icon never appears so we don't know if this plug in works or not with Adblock enabled, now do we?

Sounds like another EPIC FAIL

This review is for a previous version of the add-on (2.4.0). 

If ABP is already blocking Google, there’s nothing left for GDC to block!

As I replied below, the order of add-on installation matters. If you installed ABP first, there may be no Google resources left for Google Disconnect to block and no reason to show an icon.

By the way, you should really fix the tone of your reviews. As Steve Jobs asked, what have you done that’s so great?
