There is an mystery icon like an orange dot that appears alongside certain messages in the message list. I have attached a picture. Can anyone explain what it indicates.

I can tell you that it is NOT any of the following.

• Unread message indicator (these are shown in bold and have a green dot in another column)
• Junk mail indicator
• Threading indicator

All suggestions gratefully received.

This article https://support.mozilla.org/en-US/kb/thunderbird-and-gmail#w_understanding-gmail-labels-and-thunderbird-folders is not up to date and it isn't clear to me to what extent (if at all) add-ons are still required to sync labels between Google and Thunderbird contacts. The article points to two add-ons: Google-4-TbSync TbSync but Thunderbird already syncs both Calendar and Contacts with Google without add-ons. What's the story?

I'm moving to a new computer and am having trouble getting the migrated Tags into the correct numerical order, same as on the old computer. Because the numerical order corresponds to keyboard shortcuts, it would be so very helpful. I know there was an extension that allowed you to set the order, but it's listed as through version 38 or therabouts, so I'm not sure if it would work. I figure maybe I could edit a Tag preferences file if it's in some sort of obvious text format. If anyone out there knows, I would be so grateful for your insight. Thanks.

Hi all, Since the August 2025 update, I've noticed Thunderbird is no longer syncing some of my Gmail folders (mostly labels I created manually in Gmail). The inbox syncs fine, but custom labels show up empty or don’t appear at all.

Things I’ve tried:

Removing and re-adding the Gmail account using OAuth

Checking Gmail’s IMAP settings — all folders are selected for sync

Rebuilding folder index files in Thunderbird

I didn’t have this issue before the latest Thunderbird update. Is anyone else seeing this? Could it be a bug with label handling or IMAP path prefix?

Any advice would be appreciated!
