PLEASE put the format options back into the email task bar! My formatting needs to be done on a message by message basis. It is time consuming and counterproductive to have to go to settings each time. No matter what I tried in settings, I was not able to get Formatting back into the message task bar. At minimum, I need font, size, list and color options back in the message task bar. PLEASE HELP!

Hi-

I had this working then it magically stopped about a year ago and I can't get it back. When I try to open a pdf I get "...could not be opened, because an unknown error occurred. Try saving to disk first and then opening the file."

I have gone into settings and re-selected adobe acrobat and restarted but still can't open.

I am on a mac.

Thanks for your help! Crazy frustrating and time wasting issue.

I just opened my Thunderbird e-mail account, did thunderbid only access emails from my sbcglobal account email account or did TB download the the 100,000+ SBCglobal emails to a thunderbird file that I can continure to access?. I believe that AT&T is going to delete my sbcglobal email account as I have canceled my AT&T internet service. I see sbcglobal messages in thunderbird that go back to 2008 that I would like to read again. Will these messages disapper when AT&T disables the SBCglobal email account.

I've been wanting to access Thunderbird's encryption ability on both my laptop and desktop. However, in setting up Tbird on my laptop I notice the user Profile should stay on one computer. Can I use the same Profile on more than one computer using the same source and password? Can I open a new profile on a second computer, even though I would have to use the same email source, a local provider? If not, is there an online source of email data I can use on Tbird on my laptop. Thanks much, Bruce Bartrug

Running Thunderbird 140.5.0esr

This has been happening for a few weeks now somewhat randomly. The folders under Mail for one of my accounts keep moving around and are not in alphabetical order anymore. Most folders are OK, but a few either jump to the top of bottom of the list. I can manually drag them back, only for different folders to do it the next time.

The folders in questions are 2 levels down from Mail.

The folders in my "LOCAL FOLDER" file usually have been in alphabetical order. As I have added new folders to store emails, the new folders have not been put in alphabetical order in the "LOCAL FOLDER" folder. They have been added to the end of the original list after the "Z" items. How do I re-alphabetize the whole "LOCAL FOLDER?"

Today in two of my accounts I get error message "Unable to open the summary file for Inbox on imapML. Perhaps there was an error on disk, or the full path is too long." Two other accounts work fine so no error on disk, and full path hasn't changed.

"Could not get folder db" is the message. I've tried all the suggestions that google provided - nada

5 accounts are defined. Some filters work on startup, but new ones do not. Manually running filter results in "could not get folder db"

Hi Everyone,

I am very excited about the new PDF signature feature in Thunderbird, awesome to not have to do this externally.

However, I am still trying to find a way to streamline a common workflow for me: I get a an email with pdfs attached where I need to insert signatures in a few places and send this back. My current workflow is the following: i open each pdf attachment, add the signature, save it to a file, and then open the email reply and reattach the correct files and all of them. It is this indirection via files that actually created the biggest headache for me, as it's a bit too easy to mess up here.

I also tried going via the "reply with attachments" extension, to have the reply email with all attachments already, but there seems to be no way to then edit them in thunderbird.

Am I missing something obvious for how to do this? Given that I am surely not the only one doing this, I am hoping someone has already figured this one out?

Over 4000 previously deleted emails suddenly started loading to my Inbox. I have tried to delete them but get a message - "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox". There appears to be plenty of disk space and as far as I'm aware the file system allows write privileges as I am Administrator. I have managed to delete the messages using Up Function+Delete, (which doesn't write to the Delete folder), and have cleared all from Webmail but still have the same problem. I am also unable to receive any new emails. The email is POP3 configured. I have ensured that my Thunderbird if up to date. I operate Windows 10.

Thunderbird shows the number of emails downloaded but I can not see them in my inbox, or anywhere else. Using Thunderbird 115.5.2 (64-bit) on an older iMac on OS 10.12. Email account is gmail, and using POP. I've tried 'repair folders" with no change. I've deleted old emails from the Gmail server. Would appreciate any help.

I have Mozilla Thunderbird installed, the Yandex mail instructions say - The server name is imap.yandex.ru and the server name is smtp.yandex.ru . with such constructions, the mail does not arrive. Mozilla uses ru - com instead by default and everything works, but it feels like it's wrong because everything slows down terribly. If I change to ru, the mail does not work. https://disk.yandex.ru/i/7V9_I1XwoBLPiQ

Why can't I send outgoing email on my BT Premium email account from within Thunderbird, when the Norton VPN. I get a timed out or policy block message. Somewhat perversely, it works when the VPN connection is on. although you warn that VPN connections may be rejected.

Any info or ideas?

Hi there. This morning the Customized Menu Bar in my T-Bird was there, as confirmed by my wife... and then it wasn't. No idea what happened. I spent a long while poking around to try to find what had been inadvertently changed, and came up empty. So, went in to Customize Toolbars and rebuilt the Mail toolbar as I recalled its layout, as we use it a lot every day. Now it seems to be fine. T-Bird is kinda like Windows, where there's more than one way to do something, and sometimes several paths to the same function. I know there are new Keys, or whatever they're called, that replace or replicate the old Customized Menu Bar. But we have been using T-Bird for ages, and though I've noted all the updates and improvements over the years, we are pretty comfortable with the basics that we use, and have not made many changes. So, we're OK. Just thought it was weird what happened. Thanks for being there. Greg Moehl

Config editor has no printer listed. nothing to reset. Printer works with other applications just not TB. Re-installed the printer. Reset the space limiters, which I found were set too low. Restarted TB and computer

Hi,

we use Thunderbird for several business e‑mail accounts (for example info@… and similar), all configured as IMAP, and the same mailboxes are used by multiple people on several computers. Our mail server hostname is nickel.studio4web (Studio4web hosting).

We have noticed the following strange behaviour of messages (usually customer orders):

A new message arrives normally in the “Inbox” folder.

After some time, for example the next day, the same message also appears in the “Trash” folder, but it is still visible in “Inbox” at the same time.

We checked the headers; the Message‑ID field is exactly the same in both Inbox and Trash, so it looks like one and the same mail that exists in two folders at once.

In Thunderbird Server Settings we configured the delete behaviour so that messages are either moved to Trash or removed immediately (we tested both options), and after that we ran Compact on both the Inbox and Trash folders. However, some messages still remain simultaneously in Inbox and Trash.

We know that other team members open the same accounts in other clients / on mobile phones or in webmail, but we are not sure whether that alone can explain this double appearance of the same message (Inbox + Trash).

For example, two order emails from 03.12. were in Inbox only on that day, and today we see them also in Trash, while they are still in Inbox. No one remembers explicitly deleting them.

Questions:

Is this behaviour normal for IMAP in Thunderbird, or does it indicate some bug or wrong configuration?

Is there a way to prevent a single message from being present in both “Inbox” and “Trash” at the same time (so that it is either only in Inbox or only in Trash)?

What else should we check in Thunderbird settings or on the mail server (filters, special IMAP options, automatic cleanup, server‑side rules, etc.) to avoid such “duplicate” messages?

Environment:

Thunderbird version: 140.5.0esr

Operating system: Windows 11 Pro

Mail server / provider: nickel.studio4web (Studio4web hosting)

Thanks in advance for any help and advice.

Good afternoon, I am using Thunderbird for many years now. In the last ~2 years I have seen several times the subfolders of the mail folder disappearing from the list on the left panel. All of them are correctly subscribed. I would like to know if there exists a way to recover them different from deleting the account and recreating it. I am currently running Windows 11 Pro 25 H2 with Thunderbird 145.0.

Did anyone experienced such an issue? Thanks Riccardo

Hello,

I have a MacBook Air M2, and I'm experiencing energy usage issues related to Thunderbird. This has kept happening for a long time now actually, surviving through at least two Mac OS updates, and a huge number of TB updates. Everything's up to date. I tried to follow this: https://support.mozilla.org/en-US/questions/1269944 and this: https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems?_gl=1*86dj4d*_ga*MTkzNzQ0MjA3MS4xNzYyOTY4OTMx*_ga_2VC139B3XV*czE3NjMzMTM3NDckbzIkZzAkdDE3NjMzMTM3NDckajYwJGwwJGgw but didn't succeed. Actually, in my case, the issue is more noticeable: I normally have TB open in background - sometimes everything's fine, and the battery goes down as normal, while sometimes instead the battery drops quickly, and checking in the Mac activity monitor I can see that the CPU usage of TB is totally abnormal. When this happens, I can actually see the activity bar in TB being live (bottom right corner, as it happens when TB is checking for new mails), but never disappearing. When I notice it, I just reboot TB, and the bar shuts off as normal after a quick mail check. Moreover, checking the 24hr energy usage by app, TB is often on top with nonsense values.

I tried multiple times to rebuild the database, and do most of the tricks suggested, but didn't fix. Yes I have a huge mail archive, but the problem is not the standard management of this database: basically it seems that every now and then, TB decides to run some activity which it gets stuck in, and this kills the CPU.

Thank you in advance for your help!
