I am still not getting any help or response. The hourglass keeps coming on and making me wait to see a message.

• Please start *Windows* in safe mode with networking enabled https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode
• Still in Windows safe mode, start Thunderbird in Troubleshoot mode https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird

Does problem go away?

• If no, then the cause is either: bug in Thunderbird, something (eg a setting, file or folder) in your Thunderbird profile, your mail provider. Please post into topic the contents of Help | Troubleshooting | copy text to clipboard

• If yes, the problem is gone, then (still in Windows safe mode) ... start Thunderbird normally

* If problem is still gone, then cause is likely a program loaded during windows startup. Possibilities include: antivirus software (AV), virus/malware, background downloads such as Windows or other program updates, to name a few.  For AV information see https://wiki.mozilla.org/Thunderbird:Testing:Antivirus_Related_Performance_Issues

* If problem came back, then cause is likely a Thunderbird add-on - eliminate them by disabling add-ons one at a time in Tools | add-ons | extensions and restart Thunderbird after disabling (if you have many add-ons, try disabling half of them at a time)

If results are unclear ... possibilities include temporary conditions such as contention from other running programs, downloads related to windows update, ...

Please let us know your findings.

I don't know why this support forum added "Win 10" to my question. I am using windows 7.

I will look at and try these suggestions. What would be most helpful is if I can contact the person(s) who just created and required us to use this "new" version of thunderbird and ask them to fix this bug. This bug only existed when the "new" version replaced my older one a few days ago, without my consent. Where can I reach them? Thanks.

Can I contact the person(s) who just created and required us to use this "new" version of thunderbird, please?

It's kinda funny. when I try to access my inbox now, what I get is "not responding". That's just what I am getting here. Can I contact the person(s) who just created and required us to use this "new" version of thunderbird, please?

Those suggestions that imply that what's happening is on my end are complicated, and I might try, but I don't have much hope. As I have said, thunderbird worked just fine until we got this "new" version. Why can't we contact the people who made it and report a bug? There is no place at all to report a bug. Is there anyone out there who knows?

I don't know how to say this except to say that this support venue is where we determine whether there is a reportable problem, and how to report it - there is no short cut channel to developers.

To help us determine the issue, the initial steps of safe mode and troubleshoot mode have been already requested. They are not difficult. If it helps, please printing them so you have a reference while performing them.

Also, please screen shot the folder pane and post it here.

I decided to go another route, thanks to my expert friend here at home. It was obvious to me and to him that the problem is with Thunderbird, not my machine here. So we decided to look if we could go back to version 102, which was replaced without my consent a week ago with what turns out to be a complicated new program also called supernova. The programmers apparently think they can get more work or something by creating this new program. And even though noone is complaining here, we found many people complaining on social media about this new program that makes us wait 3 minutes or more before we can even use it because it's so complicated. We found someone to guide us about how to go back to the old program. Part of this job was to apparently do what you suggested, and going to the troubleshoot mode. But we found our way back to the program that was working just fine, and which I didn't want to replace with some new program that adds a bunch of things we don't want that slows it down.

And why do you folks put out a notice when we access this program that offers to report bugs, but no reports are anymore accepted? And why do we have to go through you Mr. Mery before maybe we can notify the programmers about this bug? Thanks for answering me, but this "support" site seems pretty useless to me.
