It does work in Chrome and Edge as well. all you have to do is the following:
1. open the battlescreen.
2. In the top left corner next to the url there should be a triangle or a circle sying "not secure", click on it.
3. select "site settings" (it should open a new tab in your browser).
4. scroll down until you see "insecure content" and in the dropdownbox next to it select "allow".
5. you done! you can now close the tab that opend and refresh the batllescreen window by pressing F5.
Any idea if this would still work via console?
