Thunderbird Community Forum

For the last 2 days or so, I cannot receive emails in Thunderbird from my Comcast email account, The app receives from other accounts. The app also sends emails from all my accounts, lets me read already-received messages and move the messages to other folders as it usually does. I just can't receive emails from Comcast/Xfinity. I note that Thunderbird had a update a few days ago.

My computer has not worked for nine months.

I've been looking at my e-mail on my phone (not in Thunderbird for Android, which pretended to send my messages but didn't). I want it on my computer.

I didn't want to do that right away, but it looks like Thunderbird started doing that automatically when I launched it. It successfully got my small account, of course, but not my big one.

It's been stuck on this for more than 12 hours. (See image. My apologies, I've forgotten how to embed them.)

Is it safe to shut the process down? Whether it is or isn't, what do I do next?

My computer is a MacBook Pro (13-inch, Mid 2012), running OS X.15 (Catalina), with Thunderbird 140.0.1esr (64-bit). The process started before I could upgrade to 149esr.

Thank you for any help you can give me!
