Firefox not displaying some tabs.

I live in France, Finistère to be exact, and as this is closer to Cornwall than Paris I have got into the habit of using the British meteo office for forecasts via the BBC News web site. HERE It is usually much more accurate, and the Weather/Beta gives pressure and temperature charts. Well, it did until about a week ago, now the Europe map comes up on screen but without the temperature, pressure, and weather tabs. I have tried disabling ABP and NoScript but no improvement either in FF3.0.5 or 3.1Beta.
The site loads perfectly in Google Chrome.
Does anybody know what might have caused this FF change in the last week or so?

Hard to tell, since I have not used the site. However, I selected the desired location, and have it in a new tab. And, it came back when I closed FF. Not sure if the FF version matters, as I am using Win98SE with FF2.0.0.20.
Aside for the fact that BBC calls for heavy snow on Friday, while weather.com calls for partly cloudy/windy, the BBC site is good.

 

Solved - Sort of!

Today FF decided that it would work properly, and put the start arrow for Flash on screen. This produces all the tabs on the weather chart.
