问题
I have a seemingly correct resource backed by a CouchDB installation. Requests are made using JS Axios. Both Chrome and Safari work, Firefox 65.0 fails however with
CORS header 'Access-Control-Allow-Origin' does not match 'http://localhost:8080, *'
The server (CouchDB) does, in fact, not deliver
'http://localhost:8080, *' as Access-Control-Allow-Origin
but
Access-Control-Allow-Origin http://localhost:8080
Access-Control-Expose-Headers content-type, cache-control, a…e-newrev, x-couchdb-body-time
due to its configuration CORS accept requests from all domains ('*').
This, as mentioned, perfectly works for the other browsers. But fails for Firefox. I really don't seem to find the resason resp. a solution for this, and keep wondering where the additional '*' comes from that, Firefox wants to see.

@sideshowbarker thanks for the hint - indeed, the behaviour was due to an extension - namely this one https://addons.mozilla.org/en-US/firefox/addon/cross-domain-cors/ after disabling this extension cors worked as expected!
