Is there no choice to say 'Not now'? Or is there, and it keeps coming back?

It persists in the lower left. It obscures content. It appears the only way to make it go away is to click the "Learn More" button. I do not want to Learn More. It persists in every email I click on in the Inbox. It persists when I open an email. It looks like a hack. Even if it is not a hack, Thunderbird should not be hijacking our user experience with this annoying demand for a click.

What happens if you click the X? I clicked the X and it hasn't returned after several restarts.

Why am I being forced to click this button? I do not want to Learn More. This is a lousy user experience. It looks like malware. How do we report this to Thunderbird for an explanation?

I didn't ask you to click Learn More; I asked you to click the X.

Thanks for that. I don't want to click the 'X'. The message looks like malware. Thunderbird should not be forcing this annoying message in the application. It should not persist. Why have they not provided an explanation? They could have sent their loyal subscribers a message alerting us to this. This is a lousy user experience. It looks like malware. At best, it is unprofessional and not user friendly. Can you tell me how to get the attention of product leadership about this?

1. I can assure you it's not malware.

2. If you refuse to click the X to make it go away, then it will remain.

3. You could report the inconvenience as a possible bug at https://bugzilla.mozilla.org/enter_bug.cgi/. If you do, please post the link to it here.

I went to the bugzilla site per your link. It appears that is for people working to resolve bugs. I want to report a bug / bad user experience. How do I do that?

This is Wayne, the community manager for Thunderbird. This notification window is not malware. The only way to dismiss it is to click the “x” which is not a button, it is a window control.

If the notification appears again after having dismissed it previously, then we have a problem.

Thank you, Wayne. I do not want to be forced to click a button that looks like Malware. I have been a Thunderbird user for more than ten years. I have not seen this before. This is not a good user experience. I did not receive any warning that this was going to be imposed on us. How often will this annoyance be forced, persistently on the application? Do I have to abandon Thunderbird?

Sorry this is confusing.

I believe I answered your first question.

The second can only be answered by you

Sadly. I will quit Thunderbird.

No problem. Thanks for reporting and helping us understand your situation.

FYI Ed this is not a bug. It is a scheduled notice to all users so they can choose to upgrade to new monthly releases or stay on ESR

Millions of users have seen the notice. I think this is the first to think it is malware.

Thank you for your follow up. I do not know what ESR is. I do not recall being notified about this monthly update option. This has been poorly handled by Thunderbird. I do not like the ugly, persistent notification in the lower left corner of the application window. If Thunderbird can't do better than this it is better that I move on.
