Allowing insecure content in Chrome or Firefox not working, Google API Explorer

Question

Trying to use Google's API Explorer to test Cloud Endpoints.

I get this error in console after seeing that nothing loads:

Mixed Content: The page at '[https :// ] apis-explorer.appspot.com/apis-explorer/?base=http%3A%2F%2Flocalhost%3A8080%2F_ah%2Fapi#p/' was loaded over HTTPS, but requested an insecure resource '[http :// ]localhost:8080/ah/api/static/proxy.html?jsh=m%3B%2F%2Fscs%2Fapps-s…3DEQ%2Frt%3Dj%2Fd%3D1%2Ft%3Dzcms%2Frs%3DAGLTcCOS-9qNfJHxVBVUBVsRh4QjbpbBLw'. This request has been blocked; the content must be served over HTTPS.zk @ apis.google.com//scs/apps-static//js/k=oz.gapi.en.CHA8zxoicJQ.O/m=client/…=1/am=EQ/rs=AGLTcCOS-9qNfJHxVBVUBVsRh4QjbpbBLw/t=zcms/cb=gapi.loaded_0:159

I've tried the following suggestions, and they do not work:

1. In chrome, click on the shield in the upper right corner to 'load unsafe scripts' - now we are in http instead of https, but above error still shows
2. In firefox, click on the lock on the upper left to 'disable protection for now' - now in http as well but still no luck
3. Followed the instructions here: https://developers.google.com/explorer-help/#hitting_local_api Doesn't seem to fix the issue either.

Will try any suggestions. Thank you in advance.

Just tested again, and instructions here are indeed correct solution for Chrome. Make sure to enter the correct port.
