Thank you so much!!

MET have now responded that the issue is not at their end. Windy, can you have a look at it, please?

It may be some issues with the API from the Norwegian Meteorological Institute because they replied to me in a Tweet saying that they are trying to fix it.

We are trying to fix it

Hope they will fix it soon.

Same v. of FF. here. Works fine. Same OS also. Both 64bits.
I can see that you have lots of addons. Try and turn them of to see if it works then?

Was wondering about this my self. The radar from met.no works, so the source should be okei.
