Active WebTextField Display on Different Browsers

Hello,

When a WebTextField is receiving focus, there is a blue frame on it wherelse the blue frame is not shown in firefox when WebTextField is receiving focus. Is this supposed to be a known issue in firefox or I am missing something?

Yes, different web browsers render the controls differently.
