Hi MintMan, I've noticed that happen before. Check with another radar, like AccuWeather. If you don't get radar there either, then the radar itself is probably down for maintenance. It should be back up and running shortly.

The radars are not down as I can access them via Safari and IOS apps. Accuweather radar does work though.

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

One issue that seems more common lately is Firefox's Content Blocking. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature:

safe mode did not correct problem. Turned off content blocking with same results.

I get a message stating the following:

Map Not Available

The WunderMap is not available on this browser at this time. Please try a different browser or update your current browser to the latest version.

The map uses WebGL, so WbGL is disabled or otherwise not working if you get this message.

You can check the Graphics section on the about:support page for WebGL related messages.

You can also check the webgl prefs on the about:config page.

WebGL is enabled on the about:config page. There are numerous other WebGL options. Which one of the others could affect the rendering of the radars?

Linux offered an update to 64.0.2 today in their repositories. Problem is resolved! Thanks for all your postings!

Good to hear. Well done.
