Weather routing has nothing to do with Firefox.
But It requires data to work:
1- Wind forecasts in the whole area (any number for forecasts)
2- Polar database for the boat
Tip: In the Winds tab, turn on the polar chart plot.
If the polar chart won't show,
no polar database is loaded.
Check the polar database settings.
Polar databases now come in 3 choices:
1-
new multi-sail polar database (*.xml)
(this is required for the mobile regatta runner)
2- The traditional single sail format (*.csv)
3- My polars (also *.csv) build with points collected as you go.
You can keep the 3 loaded and switch using the radio buttons.
Make sure that at least one is loaded.
Look for version 1.97b that corrected one issue with FF4.
