Error in Chrome: Refused to execute script from ... because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

Jira-Issue-Collector works not in Google-Chrome. Browser console shows error:

"Refused to execute script from ... because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled."

In Firefox there are no errors.

Thanks,
