After running your command line, I saw the firefox download msg. The prompt for the 87.4MB update appeared again and I said yes. I then rebooted and ran you command again. This time the firefox msg was missing. I imagine the issue is resolved. I'll post again if the 87.4 reappears. Thanks for your support. I appreciate it. Just to be complete, I will post the output when I ran your line again.
