Incidentally when I upload sketch in my Uno , it does it successfully .

I am running windows 10 with latest version of firefox browser.

Hello,

Did you select the correct model of the board?

If BOTH all the COM PORT and the BOARD and the FLAVOUR < ( if needed) are correct there should not really be any issue.

Other problems could arise from USB 3.0 ports, Antivirus, Incorrect plugin installation/corruption, bad USB cable and a few more common things.
