The source map error should cause no problems (unless you are trying to debug the stable version of Kee) and in any case should be resolved in the next release - see https://github.com/kee-org/browser-addon/issues/121
I think you are saying that you have a problem with the way Kee works on Intel.com though? If so, please can you provide more information and some detailed steps to reproduce the problem you see… after looking at the relevant part of the troubleshooting guide of course.
