The Usual: Oops! Looks like this feature isn't working properly!"

Works on one pc but not the other. Both have the same Windows 10 OS installed.  Only appears when I try to load data for a city. 

I tested a lot of variables to loacte the problem.  For me, it turned out it was my Firefox browser's internal privacy permissions (I had private browsing enabled). I clicked the lock icon on the Firefox address bar and changed my permissions to allow the page to "load pictures." When I did that it automatically gave weather.com permission to access my location (I don't think it needs that info if I am looking at the weather in a city in another part of the country, continent or world, but it seemed to go with the load pictures permission.)

I have no problem doing this as I have plenty of other tools that take care of the more malicious trackers on that website for me. The Weather channel has more privacy-invading trackers than any site I've ever used, including Facebook and other social media or even shopping sites.
