I installed x64-Chrome, x64-Chrome-dev, and x64-Chrome Canary. (Windows box)
x64 Chrome reported that libgen 0.0.5 was corrupt and I was unable to repair.
x64 Chrome-dev installed plugin without error, no plugin pop for amazon.com
x64 Chrome Canary installed plugin without error, no plugin pop for amazon.com
Based on above test I can confirm its not working (for me)
