Delay moving messages to and from 4 certain mailboxes (win10, v152)

It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

For a few days I'm having trouble with Asana mails (notification mails informing me about replies, comments, etc).

Clicking on the mail to view it freezes Thunderbird for a good 5 seconds while one CPU core spins at 100%. This only happens with Asana mails (or at least I haven't found any other problematic senders).

I guess it's a problem with validation or parsing of the mail's HTML content. But I don't know how to debug this.

I can't pinpoint exactly when it started happening, but it was around the time I've switched to the [new snap release track](https://support.mozilla.org/en-US/kb/channel-choices-thunderbird-snap-and-flatpak#w_snap-channel-changes-in-2026). But since this happens with Snap and Flatpak I think the culprit may be the 153.0 update.

Things I've tried:

  • Clearing cache and msf files.
  • Troubleshooting mode with add-ons disabled.
  • Reinstallation. Creating new profile + importing old data.
  • Switching from Snap to Flatpak
  • Switching Message Body display to Plan Text or Simple HTML.
  • Disabling HW acceleration.
  • Checking console for suspicious output.

Anything I can do to create handle the problem or collect information for a proper bug report?

When I write and send a message. A window comes up saying copying message to sent folder and then it won't close. i.e. it just stays there. When I open up thunderbird again it says the message has been sent but I still can't close the window that says copying message to sent folder.
