We now have a content security policy in place where the server indicates to the browser what sites we expect various sorts of resources to load from, so if you trick the browser into using a different source like this then it will get rejected by that policy.

If you look at the javascript console you should errors telling you the CSP is being violated by those load attempts.

@fosiul, Please let us know if putting your own leaflet-based website in place lets you render maps.

@tomh, Thank you for the confirmation.

It looks like someone has (very recently) changed something that's broken this use of switcheroo. My guess is that it's at the osm.org end rather than in Chrome or Switcheroo. For more background about what this particular bit of browser nannying is supposed to do, see here.

In the meantime, a simple leaflet-based website is probably the way to go. There are lots of leaflet examples around, and here is a simple one I created earlier.

If you want to generate lots of tiles then have a look at https://wiki.openstreetmap.org/wiki/User:SomeoneElse/Ubuntu_1804_tileserver_load - there's a render_list example there and also a "just the tiles in one area" one.
