Thank you for submitting this idea! We are currently planning to experiment with weather in the near future 😊 I'll happily update this thread when it is available to experiment with!
I love this so much. I used to have a taskbar shortcut to AccuWeather that randomly stopped working multiple times, and going to the actual website would never send me to my location for some reason. I eventually gave up on it but today this appeared and it solved both of those problems. Mozilla, please don't remove this feature.
