MDN offline Application Render Error

more options

Hello, Today I downloaded the offline version of MDN for HTML from Kapeli. I extracted it and ran it with Firefox but error appeared, it was saying: "Application rendering error. An unhandled error occurred in the application. We apologize for the inconvenience!" after that I opened it with Edge and everything was working just fine. I tried to reset Firefox, but this didn't work either. Can you help me with this problem, I would be grateful.

Are you sure it can run in Firefox on a file protocol URL? There are additional security restrictions with file: that do not apply to http: or https:.
