I just got a new Macbook Pro retina, installed Mountain Lion on it, downloaded Chrome, and tried to install dotjs, but Chrome is telling me "Extensions, apps, and user scripts can only be added from the Chrome Web Store." and "learn more" sends me to this page http://support.google.com/chrome_webstore/bin/answer.py?hl=en&answer=2664769&p=crx_warning
Any idea how to get around it?
