From the file menu (press the ALT key to toggle it if is hidden) or from the Firefox button at the top left,go to Help--> About Mozilla Firefox,the version number you're currently using will be displayed.

Seems to be 4. Thanks,altho message below Google panel on start page is still urging me to upgrade! Suppose I just ignore it until it tells me version 5 is available.
