How to get Firefox to not continue to show "Transferring data from..." in browser status bar after a
- by Edward Tanguay
The following silverlight demo loads and displays a text file from a server.
However, in Firefox (but not Explorer or Chrome) after you click the button and the text displays, the status bar continues to show "Transferring data from test.development..." which erroneously gives the user the belief that something is still loading.
I've noticed that if you click on another Firefox tab and then back on the original one, the message goes away, so it seems to be just a Firefox bug that doesn't clear the status bar automatically.
Is there a way to clear the status bar automatically in Firefox? or a way to explicitly tell it that the async loading is finished so it can clear the status bar itself?

<TextBlock Text="{Binding Message}" />
