As of Google Chrome version 42, users of Copy2Contact for Salesforce.com are seeing the “Oops! Chrome wasn’t up and running” message over and over when they use Copy2Contact.
It looks like Google is removing the NPAPI plugin functionality from Chrome that Copy2Contact relies on to do its thing. Starting with Chrome version 42, NPAPI is disabled by default. For now, you can re-enable it but we’re looking for a workaround for a future release.
Re-enable NPAPI functionality by entering the following in the Chrome browser URL bar:
Then click “Enable” under the “Enable NPAPI” heading (the first entry).
Completely close all Chrome windows and then restart your computer to be sure changes take effect.
