Expected popup for Gmail login is missing. "The file does not have an associated app"

J and N Larson

I had to reinstall Thunderbird after doing a clean install of Windows 11.

Since installing, the expected login popup for Gmail doesn't appear. I get the attached error message instead.

Yahoo worked fine after a few tries. What is the problem here, and how can I fix it?

I tried just now to set up Gmail manually in Thunderbird. It gave me a message that it updated the information automatically. I get the same error I posted yesterday.

Please help. I need to move my Gmail messages into Yahoo. I have Thunderbird for only that reason.
