@mrhurricane Sorry for late reply. Thank you, this was the problem. I was following a privacy guide when configuring Firefox, and that's why I disabled privacy.resistFingerprinting. I'll enable it for now because I like Windy, but hopefully it doesn't cause any privacy concerns... But seriously, thank you for figuring this out!

@JimInSanDiego this occurs on all elevations.

@TomSlavkovsky I am on Windows 10. It happens on all zoom levels and all layers. Though on different layers the color may change. For instance instead of being all purple it will go all brown.

Hi, Windy works great for me on browsers like Chrome and Edge, but on Firefox I get a purple screen. I have attached an image of this. All weather overlays appear to be "maxed out" with the highest color. I've tried disabling all extensions and it still doesn't work.
