A small popup will appear in the lower right of my screen stating that FIREFOX 32.0.2 is available for downloading. I click on "Download Now". Another larger popup appears entitled "Software Update". This is completely blank except for three buttons in the lower right corner. The first is suppressed. The second, "FINISH" is enable. When I click on it, nothing happens. The third, "CANCEL" doesn't respond when I click on it either. This is my first experience with this issue. Normally I am able to download and install new releases of FIREFOX without incident.
