Updates
Why does my version leave me a message to download the latest version of Thunderbird when I am already running it? I'm currently running version 102.3.1 (64 bit) and I constantly get messages that Thunderbird couldn't update and I should download the latest version. However, the version it wants me to download is the very one I'm already using. This is annoying since it occurs daily....

Avast AVG and Mcafee are known to cause problems with update. If you use Avast, try the suggestion at https://support.mozilla.org/en-US/questions/1384853#answer-1525849
Other possibilities, are you running with a VPN or proxy?
