update your flash player or use a different browser
Thanks Nolefan. I updated Adobe Flash Player and that seems to have have done the trick.
Both Firefox and Adobe have pissed me off this year. Firefox now updates often and gave messages that Flash Player needed updating.
I would go to Adobe and it is the most convoluted site I know for finding and downloading an update. It was easy tonight but awhile ago it took ages to find and then it took ages to download. For some reason (most prob my fault) they have not installed for some time.
Whatever, looks like I can now get on and solve the other 100 things
