I've come over from Postbox as that app is no longer being supported. In Postbox there was one file (panacea.dat) that controlled how many old locations you would see in the Move To menu. Once the number of items got to be a bit too muchj, I would delete that file and it would clear the Move To menu item. Is there such a file in Thunderbird that controls the Move To menu, or can it somehow be controlled by a setting in Thunderbird? Thank you.

I think I understand the difference between "folders" and Gmail "labels". So, I'm curious. When Thunderbird synchronizes with Gmail, does it create local physical folders for each of the Gmail labels in use, or does it use the Gmail label scheme locally? If a message in Gmail has two different labels attached to it, are there actually two copies of the message created locally in separate folders or not?

I sometimes want to give Message Labels two different colors. But it stays in the first selected color. It would be great if, regardless of how many I select in the Message Labels column, they appeared as small boxes with their colors (like Outlook). The current state might be good, but with multiple options, the list view mode and the reading view mode seem illogical.

In short, the same colors as the multiple boxes in the Reading section should also appear in the mailing list.

I think that's how it should be logically.

Up until last week my Thuberbird Gmail account had "All Mail" and "Archives"

I've recreated the gmail link, enabled/disabled gmail label but it refuses to change

The problem is best shown in the images where the Gmail link is to All Mail but the name is Archives

Am having an issue with creating a “new folder” in my inbox. I create the folder, shut Thunderbird down, re-open it and the folder is not there. Did this three times, same result. A

lso, having an issue with tagging. I will click on an email, right click, and nothing happens. I have to click on another email, click the original email, then I can tag it. I suspect a corrupted profile but, not sure. Any ideas?

My Tags window & folder [View, Folders, Tags] layout stopped properly displaying all my items with the appropriate "tag" set in the past few updates to T'bird. I recently switched to version 140.4.0esr but the problem existed before that in 140.2.1 as well. Is there any way to force a "rebuild" of the Tags window so that all my tagged items show in their appropriate categories, with appropriate statuses [read/unread, etc]? Otherwise, the Tag feature is no longer useful.

Witam, Mam problem następujący. Co jakiś czas z mojego konta znikają wszystkie etykiety jakie mam na poszczególnych mailach. Co może być przyczyną? Czy da się jakoś przywrócić je??

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.

I recently had to reinstall TBird 144. Now it does not display the TAG selections in the email headers. My program inbox is set to view: Classic, Folder and Message pane. The attached jpg show how it used to look. Thanks in advance.

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?

In Outlook, it would say that "I replied to this message on xxx" in the header (not sure if that is what it is called, but near the top). I found it helpful to at least see if I have already replied to a message received. Is that feature available in TB?

When I save an email as a Draft, it appears in bold in that folder, so I am aware it is there. If I edit it and save it again, without sending it, the bold disappears, so I forget it is still unsent (unless I happen to click on that folder). Other email software allows you to click a button to highlight a particular email, but there seems no way to do this in Thunderbird.

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 there,

I use extensively tags in my workflow, and I just switched from Gmail to Thunderbird. My only problem is that in Thunderbird, tags apply to a single message and not to the whole thread.

In other words, if I reply to an email with a certain tag, the answer is not tagged.

Is there a way to apply tags to a message and then the whole thread will keep the same tag?

Tank you in advance for your help, Best regards,

Livio

My tags stopped working, right click -> Tag no longer has the list of tags, although 'Manage Tags' shows my list of tags and 'New Tag' applies the tag to the selected message, but no tags appear on right click-> Tag list. I'm using Mac OS Version 15.5 and Thunderbird 139.0.2 and have rebooted and reinstalled Thunderbird to no effect. Thanks for any help you may have!

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!
