Can't see the map on Firefox

I’ve been using FlightAware for years with no problems. Now, when I track a flight using Firefox on my desktop computer the map is blank (blue). It works fine on IE, and it works fine on Firefox on my notebook computer.

Any suggestions what I need to tweak on Firefox on my desktop to get the map back?

What they would tell me is to try clearing your cache and see if that helps.

That did it! :smiley:

Cleared the cache.
(Tools - Clear Recent History - check “Cache” = Clear Now)

And now the map shows up fine.

Thank you porterjet!
