Browser tool doesn't support file:// URLs

Wish you’d fix this and it’s in Windows just as well. Browsers have been running local files forever, so it’s quite unusual.
An interim fix is to use Python’s built-in http.server (thanks to this “how to” discussion), by running:

python3 -m http.server

Or in Windows:

python.exe -m http.server

This will serve http://127.0.0.1:8080, and you’ll be able to open any local file using http://127.0.0.1:8080/[local_path] by just modifying [local_path].
