Thanks for flagging this. I tried to reproduce it in Firefox (153, with strict tracking protection and HTTPS-only on) and it loads fine for me, so maybe something specific to your setup? The error means the request to open-meteo never got a response. Firefox does its own DNS and proxy handling separately from macOS, which might explain why Chrome and Safari are fine.

A few things that would help narrow it down if you have a minute: - Does it work in a private window? If so it might be extensions or some stale cached state. - If it fails in private too, check whether Firefox has DNS over HTTPS or a proxy set up (Settings -> Privacy and Security, and network Settings). - Firefox console says why a request was blocked. If you paste the red line here I can dig in.

Either way, that error message from me is pretty useless. I'll be more descriptive.
