"Change location" might be disabled/hidden in the three-dot Weather menu, you may need to enable this via about:config.

• about:config => browser.newtabpage.activity-stream.weather.locationSearchEnabled => true

That solution worked, but it raises another question:

Why was that feature disabled in the first place? I certainly didn't disable it–I didn't even know it existed.

I had to re-install firefox and this new widget showed up. I like it :) I also did not have "change location" which I found reference to while searching this issue but I do now. Yes, why was it disabled in first place?

Hello--

In about:config, mine was already set to 'true', but I still cannot change the location, which is off by roughly 15 miles. Suggestions?

Do you see the menu I posted above if you click the three-dots in the weather gadget? Can AccuWeather show data about your exact location if you visit its website directly via the address bar as it is possible that your location isn't available and the website switches to a larger city nearby?
