Thunderbird has more "Mac beach balls" than an Apple company volleyball tournament. One email account. (Also, 3 Sent foldersS)

Thunderbird gives me the “beach ball” for 2-3 minutes every time I try to do something (bring the running app to the foreground, open a message, click delete, click reply, click send, etc) It started a few weeks ago (shortly before Christmas, perhaps?). Occasionally, it behaves itself and acts normally, but more often than not, I find myself hopping on my phone to reply or delete messages because I just don't have the time to do it on Thunderbird.

I've used Thunderbird for many years. I use it for one email address (a Hover account) and only one user profile. In an effort to fix this, I have restarted the app, restarted the computer, and deleted and reinstalled the app from your website.

I'm using Thunderbird 52.5.2 (64-bit) on a 15-inch Mid-2012 Macbook Pro running Sierra 10.12.6

How big are Inbox, Trash and Junk folders both in terms of number of messages and size (MB)?

more options

Inbox has 14 messages Trash has 155 messages Spam has 46 messages

I'm not sure how to see the MB size. Could the Sent and Archive folders also be a contributing factor? I'm not sure why there are three Sent-related folders, either.

As an example, just now, I went to bring the message with the notification of your reply forward from behind the browser window where you can see it in the screenshot. As I moused over the title bar of the message, I got over a minute of beach ball before I could even click on the title bar to bring it forward and close/delete it.

Did you update macOS in this period?
