Select drop-down not functioning properly on Autorefresh in Firefox browser.

Question

I had enabled Auto-refresh of 20 seconds in HTML code having 'SELECT Drop-down" as one of the elements in the screen.

If both the IE and Fire-fox browsers are opened simultaneously and if i change the value present in the 'Select Drop-down' and update the configuration from the 'IE' browser, the text,radio buttons are updating properly on the "Firefox browser" on refresh except the 'SELECT Drop-down'

This issue is not present in IE browser.

Please update the fix for the above mentioned issue ASAP.....
